Hydraulic press for fuel briquettes with your own hands

Press for fuel briquettes with their own hands: the scheme of the hydraulic unit and instructions for its manufacture and assembly

Sawdust, agricultural waste, leaves and other plant debris are all excellent fuel.

But for the usual boiler it becomes “digestible” only in the form of pressed briquettes. without treatment it will have to add every 5 minutes, and most of it will go through the grate.

Powerful presses for working with such raw materials are produced in abundance today, but in view of its high cost it is profitable to buy such a unit only in order to organize constant production.

An average man has to make a press for the manufacture of fuel briquettes with their own hands.

Production technology of self-made press for sawdust

The starting material, most of which is usually coming from woodworking enterprises sawdust and off-cuts of wood, is crushed and thoroughly dried. In the end, the humidity of the raw material is brought to 8%. 10%.

In addition to the components of plant origin. wood waste and husks of various crops. for the manufacture of briquettes can be used coal dust.

The next step is actually making briquettes from the prepared mass.

One of two methods is used for this:

• Pressing: Raw material is poured into round or rectangular forms (this element is called a matrix), where it is pressed with a strong hydraulic press. The part that directly affects the raw material is called a punch. The machine develops a pressure of 300 to 600 bar.
• Extrusion: the extruder is very similar to a screw mincer. The screw presses the product through a gradually narrowing forming channel and the resulting pressure reaches up to 1000 atm.

Strong compression leads to the following phenomena:

• The temperature of the mass rises greatly.
• The raw material particles begin to release a sticky substance called lignin. When heated, it binds the crumbly mass reliably, transforming it into a solid, solid briquette.
• The density of the material increases to 900. 1100 kg/cubic meters. м. For comparison, the density of wood is only 500 to 550 kg/cubic. м. Together with the density increases and the energy value of fuel per unit volume: now its stock for the winter will take up half as much space. And the pressed briquette will burn longer than a normal log.

Then the briquettes are heat-treated (after the extruder they are cut into logs of equal length) and put into storage.

This. This design is excellent for its intended purpose. Made all. Performance requirements not industrial. Enough for home use all year long

And after drying the briquette does not crumble?

I wonder if anyone has tried soaking dry paper and sawdust in waste oil instead of water. And then squeeze the oil in the press. The advantage is that there is no need to dry anything, if immediately in the oven))))

And the dry press how hard it is to press?

Bravo, this is the most original and practical design. a little tweaking and subscription

Buy a pair of door return springs, they are thicker and thinner, thin is inserted into the thicker and out of them, cut in half, make the return piston. This will simplify the work and make it more convenient, reducing unnecessary return operation.IMHO, too large diameter of the cylinder, at a glance, about 150mm, which is 180cm in area. At a jack pressure of about 2000kg get only 11kg/cm in pressing a briquette that malovato, for quality results, it is desirable to create the pressure 20-30kg/cm or more to get good results and the diameter of the cylinder 90-100mm would be ideal.When preparing a paper mixture, I advise you to buy somewhere at a flea market or make yourself from fur. To obtain cellulose pulp after soaking, and not to bother with mixers and other agitators, and immediately cut the cardboard into strips 5-10mm wide, and then cut them across to “smaller pieces” To get ready pulp after soaking, and not bother trying to crush large flakes with an unsuitable tool. All the more that this work on the cutting can be distributed in time and not be tied specifically to the moment of pressing briquettes.Good luck!

That’s why this construction is necessary. Yes, even for yourself, you will fall in love with these briquettes to make at this rate and labor. not a bad way to dispose of household waste you say?? Yes, it’s easier to burn the material as it is, than that kind of perverted personal time and forces

There are ideas for making wood litter for cat litter ?

How long does it take to dry the briquettes if you store them under a shed somewhere ?

You’re. well done! Very useful stuff! Thank you!

At retirement it can and will do and at work even even yuyu in 10 euros per hour will either design dopilivat to increase productivity or work on the basic work and briquettes stupid buy

Do you think the rhombic jack can be applied to your invention?

Tell me what angle the press is made (relative to the horizon)?

Hello! Would you be able to manufacture a table press for me in Kursk? Very much needed in the garage. Huge request!

How can you make briquettes of coal with your own hands?

It is impossible to implement the industrial technology at home. The reasons. the high price of the equipment for the production of coal briquettes, high energy costs and the need to coordinate their actions with the local authorities. But the owner of a private home and does not need to deploy the grand scale of production, in order to provide heating for your home. Enough to make 3-4 tons of coal briquettes, which is enough for the entire winter.

Pressed coal briquettes can be obtained in two ways:

• Weld a machine for shaping briquettes from rolled metal and extrude products by hand;
• assemble with our own hands a screw press to briquet coal fines by extrusion.

In either case it is not possible to achieve characteristics similar to those of factory-made fuel. But you can successfully heat your home by burning homemade briquettes instead of coal dust, which is much more convenient and practical.

Pressing by hand

For manual extrusion is well known to many craftsmen. a machine for making bricks at home. Its frame is welded from profile pipes and angles 40×40 mm, the top is installed receiving hopper. A manual mechanism for pressing products in a rectangular shape is attached to the frame. A drawing of a homemade press for manual coal briquetting is shown in the figure:

Rectangular shape, used for the manufacture of bricks, can be replaced by a cylindrical, and placed inside the plugged tubes, so that the products were through holes. They are needed for the best combustion of coal briquettes made by our own hands.

The technology of hand-made coal briquetting looks like this:

• The raw material should try to be crushed. The smaller the fraction, the stronger and better the homemade briquette will be.
• Pour a little water and stir the mixture so that it forms with your hands. Some homemakers add clay as a binder, but this will increase the ash content of the fuel.
• Pour the mixture into the hopper, and from there fill the mold. Squeeze the briquette by pushing the lever.
• The lever pushes the product outward on the return stroke. It should then be removed and placed on a sunny spot to dry. Details of the pressing are shown on the

Briquetting on an extruder

This more productive method will require the financial cost of assembling an auger press consisting of such elements:

• The body is made of a thick-walled steel tube, turned inside to the size of the screw, or made of a single piece of metal blanks on a lathe;
• auger made of carbon steel of increased hardness;
• a die with one or more holes is made from the same steel;
• electric motor of at least 4 kW;
• belt drive on multi-strand pulleys (at least 3 belts);
• receiving hopper.

Note. Instead of a belt drive it is possible to use a gear drive, but then the drive will be rigidly connected to the shaft. In the event of a malfunction, the gearbox or auger can break down.

How a briquette extruder works and a homemade screw (right)

The most difficult part is to make the body, the die and the auger. For this it is better to ask your familiar turner, he will at the same time make you a multi-strand pulleys of the required size. Please note: the pulley diameters should be chosen so that the screw rotation speed does not exceed 200 rpm. Powerful motor of the machine should be grounded and connected to the house power supply network through circuit breakers.

Small home-made extruder

The briquetting technology on an extruder is fairly simple and is implemented in a few steps:

• Grind the raw material, if possible, and mix it with water until it reaches a thick consistency.
• Turn on the motor of the extruder and use a shovel to load a portion of the coal mixture into the hopper.
• Break off “sausages” appearing from the holes in the matrix to the desired length and lay them on a shelf for drying.

The process of making fuel briquettes from coal is shown in detail in the following

On the usefulness of coal briquettes. conclusions

If we reason theoretically and take into account the assurances of the manufacturers of coal briquettes, then they should beat all other types of solid fuels in terms of calorific value. After all, only pure anthracite is capable of releasing 7.7-8 kW per 1 kg. Firewood, pellets and wood briquettes are far behind by specific heat of combustion, because they do not emit more than 5 kW/kg.

But judging by the reviews of users of solid fuel boilers on thematic forums, the demand for briquetted coal is inferior to any varieties of wood for such reasons:

• do not burn well and give out little heat;
• form a lot of ash, or even pebbles, repeating the shape of briquettes;
• Crumble into dust even during transportation;
• emit too unpleasant an odor before and during combustion.

If you analyze all the reviews of coal briquettes, it turns out that 70% of them. negative. This is due primarily to the fact that fuel manufacturers are trying to make a profit, using waste raw materials. sludge, charge and other unneeded varieties of coal and lignite. Briquette, compressed from the remains of anthracite, is not common.

Hence the conclusion: if you want to get a good fuel, then use the appropriate raw materials for briquetting their own hands. When you have only dust and fines of low-calorie varieties of coal at your disposal, it is not always advisable to press them. On the other hand, such briquettes can be burnt together with firewood, reducing the cost of buying them.

How to make briquettes from sawdust

Fuel briquettes are produced in various shapes: cylindrical, rectangular, octagonal. Cylindrical briquettes are convenient to use in any kind of fireplaces or stoves. Rectangular products are easy to store and use.

Besides fuel briquettes from wood waste are also made wood briquettes, Eurogroove, pellets. Eurofuel is a biofuel, for the production of which the remnants of hardwood are used.

Good characteristics have wood briquettes. These are odorless, and their smoke gases do not contain substances harmful to human health. This type of fuel burns almost without remainders, only 1 % of ash is formed, which can serve as a fertilizer in agriculture.

Another modern type of fuel from wood waste, which is effectively used for heating a private home, are pellets or fuel pellets. They are made by pressing at a certain temperature from plant raw materials.

The largest amounts of wood fuel are produced by the Russian company RUFRUF. Its branches, where you can buy sawdust briquettes and wood briquettes, operate not only, but also in other regions of the Russian Federation.

However, despite the large selection of wood fuel on sale, both from domestic and foreign suppliers and the opportunity to buy it in any store in the country, many individual homeowners are wondering how to make briquettes from sawdust with their own hands.

Eurogroove with their own hands

Every owner of a private home faces the problem of disposal of various types of waste, which lends itself to combustion: the remnants of branches after pruning fruit trees and shrubs, vegetable garden residues, all kinds of husks, straw.

Making briquettes with their own hands allows you to provide dacha heating fuel almost no ecological degradation.

From personal experience I want to share how to make in the economy evrodrov with their hands. I will begin with the fact that this topic interested me in its novelty 5 years ago, when wood briquettes only appeared on the market and were used only in charcoal grills for cooking kebabs.

I had to look a lot of Internet and manufacturing technology, equipment and auxiliary materials.

Over the years, something was borrowed from other enthusiasts, something occurred to us, something friends suggested, but now in our house heating only on Eurofuel. We use them to fill the solid fuel boiler and use in the fireplace, saving on heating costs and maintain ecology.

It all started from making a mini-press for briquettes. Not to increase the cost of briquettes, it was set the problem. the equipment should not be electrical or hydro-independent.

So it was decided to make a lever-operated or screw-operated press. The basis was the press forming a paving tile.

How to make Euro fuel with their own hands

Before the modernization, decided on the form and size of the briquettes, so that the heating with their own hands was not expensive. Since it is easier to produce a cylindrical briquette, this is the form we chose.

Selected the thick-walled tube of the required diameter and height. This is our mold, where the briquettes are made.

Under the action of the moving press surface, placed on top of the tube, which is moved by a system of levers in a wooden structure or by the forces of a screw pair in a press made of metal profile.

For safe operation, the press is rigidly fixed to the supporting frame. This equipment is installed, both on the site, and indoors, can be easily transferred to the desired location.

The mass for eurodrops is prepared in the following proportions: 10 kg of wood and other vegetable shredded waste and 1 kg of clay, which is used as a binder. We add water to the mix so that the resulting mass is easy to mold.

The received mass is put under the press and with the help of punch is pressed, ready briquette is put for drying in the sun.

To increase the strength, each workpiece before pressing it we wrap with paper or rags.

That’s the technology and equipment, I would like to see Комментарии и мнения владельцев, maybe, who has a less time-consuming technology and more efficient equipment, made their own hands.

Heating with pine sawdust

Those who have a house in the countryside, sooner or later think about heating it. There are several types of heating. gas, electricity and solid fuel heating. To date, gas and electricity are expensive energy carriers, and not all localities have communication for them. Autonomous heating is the most economical and at the same time is able to provide the most comfortable level of accommodation. Of all the types of fuel sawdust is the cheapest in cost. Our country has a huge number of woodworking plants, the lion’s share of which deals with the processing of coniferous timber. Sawdust is the waste from the processing. The good news of recent days was the news about the possibility of heating with pine sawdust, which alternative name is “eco-firewood. The difference between pine sawdust and other fuels.Pine sawdust heating compares favorably with alternative fuels. The heat conductivity is much higher than that of wood and some kinds of coal. Pine sawdust briquettes do not need additional drying before putting them into the furnace. Much less space is needed to store pine sawdust than for coal or wood. When they burn, they emit a stable temperature, and they burn for about 4 hours. This makes it possible to store the fuel less frequently. Produce incomparably less ash. And finally, their cost, significantly different from alternative combustible materials. Features of heating with pine sawdust. For home heating pine sawdust is used, as well as briquettes, pallets, which are produced by pressing at high temperature. For heating, ordinary stand-alone boilers for solid fuels can be suitable. But there are also special, working on sawdust. As a rule, sawdust boilers are used for water heating systems. The advantage is the low price of the boiler itself, as well as the original combustible material. It is also worth noting the high environmental friendliness of the fuel. After all, pine sawdust is a natural material, and even in pressing them does not add any synthetic substances. Sawdust from conifers contains more resin, due to this they give more heat than their deciduous counterparts. In addition, they better maintain a constant temperature in the room.

Pluses and minuses of heating with pine sawdust.

The advantages are. The indisputable environmental friendliness of this material. After all, even the combustion does not emit harmful substances. Low price of fuel, because sawdust is essentially a waste of the woodworking industry. Today there are fully automated boilers that control all working processes. Maintenance of such a boiler is significantly lower in cost than similar boilers. Nowadays there is a large selection of pressed sawdust, which can be sealed in any package. The disadvantages are. Sawdust is a loose material, due to this it is not very convenient to transport them. On this basis, it can be argued that heating the house with pine sawdust, is much more practical and economical than other alternative material.

Sawdust press with their own hands: photo, video and description

Self-made press for the production of briquettes from sawdust: making it with your own hands.

Tons of sawdust are piled up in joiner’s workshops and sawmills. It is an excellent almost free fuel, but only for specialized stoves. If you compress sawdust into briquettes, then they can be heated by any stove, though burzhuyka. To do this, you need to make a press. Consider how to assemble and automate its hydraulic system.

Materials for making the press:

There are many drawings of the press device. The main difficulty in its manufacture is to assemble the hydraulic pressing system. The power unit in the proposed version is a 4 kW motor. It must be connected to the oil pump through a homemade adapter.

A hydraulic oil pump is connected via a directional valve to a hydraulic cylinder, which pushes the sawdust directly. The system is also supplemented with an oil tank. It feeds the pump and drains the return from the directional valve. In essence, the same principle is repeated that is used on any tractor.

This kind of mechanism works in manual mode. Exit and retraction of the rod can only be performed by shifting the lever on the directional valve. It is inconvenient, because the operator must deal with the loading of sawdust.

A simple mechanism is provided for automation. The directional control switches are linked by a system of levers to the spindle. Limit switches are assembled that move the lever in a snap action by means of a spring. When the rod reaches the end, it pushes the lever itself, and the distributor switches over. This mechanism works in two directions.

Step by step: how to make briquettes at home

If your goal. not a hard work with a good profit, and the needs associated with heating only your home, it is not very practical to buy equipment. The machines cost from 300 thousand to one million, that is, they will not pay off soon. The press can be made manually, by yourself, of your own production. And here we have two options. to make a press from scratch, or to use an already existing mechanism.

In addition to components of plant origin. wood waste and hulls of various agricultural crops. coal dust can be used to make briquettes

So, let’s say you are making a press from scratch. To create the force, suitable for compressing the raw material, you need a lever or screw mechanism. A lever press can even be made of wood, but a screw press will require steel billets and a lathe.

Of course, it’s easier to work with an already ready mechanism. You have, for instance, a jack or a hydraulic press. You need to add a matrix and a punch to this machine. But no matter how great your own hands would not make a press, it can not achieve such force, which are needed to produce lingin. That’s why we have to add binding agents to the raw material. The easiest option is cheap wallpaper glue.

You can also add clay in proportions of 1:10, also some types of soaked paper are used. For example, corrugated cardboard already contains lingin, and in contact with moisture, its binding properties show. Interestingly, if we are talking about home briquettes, then the material is not dried, but soaked in water for better bonding of the particles. And the ready briquette is dried in the fresh air.

Drawings and diagram of a press for fuel briquettes

Lever and screw presses do not require the use of purchased items. But their pressing power is not so enviable. That’s why it is more profitable to build a press on the basis of a hydraulic jack. The design can be electric motor and manual drive.

• A punch is attached to the hydraulic unit and its dimensions must correspond to the dimensions of the matrix, where the raw material is pressed into a briquette.
• For the manufacture of a matrix a thick-walled tube is used. That is if to take the simplest version. To let the air and moisture out, holes are made in the walls.
• A matrix must have a removable bottom. When it is removed, the briquette can be pushed by the punch into the receiving tray.

The finished mechanism is supplemented by two handles, they are needed for convenient transportation.

The briquette press can be made from pipes and galvanized steel. The tube is approx. 25 mm in diameter and the punch stem is cut from it. Billet for the matrix, as already mentioned, is made from a thick-walled tube, its diameter depends on the size of the briquettes.

Rules of Usage

If you want to heat a regular oven or fireplace, the briquettes are easy enough to use. just like with wood. In a brick stove and fireplace, the heating time should be no more than two hours. If you do not watch it, the masonry can start to collapse.This is interesting: making biofuel for the fireplace yourself. If softwood briquettes or bark are used for firing, the chimney must be cleaned often enough. On its walls will remain volatile compounds formed from the abundance of resins. In smoldering mode the burning time of sawdust will be longer than that of wood. One firewood filling is enough for one night. But the chimney also clogs faster. Cleaning is recommended twice a year.

In addition to the hydraulic unit, some varieties of rolled steel will be needed:

• Stud.
• Equilateral angle 100×100 mm.
• 3. 6 mm thick sheet. The punch will be cut out of it. The thickness of the billet depends on the diameter of the die: the larger it will be, the thicker the punch must be.

Of the same sheet cut removable bottom for the matrix.

• Tube with a diameter of 25. 30 mm. the punch rod will be made of it.
• Thick-walled tube. a blank for the die. Diameter depends on the size of briquettes the user wants to get. The thinner they are, the higher their density is, but the productivity of the machine will decrease.
• Large-diameter pipe. billet for the mixer body. If there is no suitable pipe, the drum can be made from a sheet of tin.
• Galvanized steel for making trays.

In total we will need two trays. for loading of prepared material into a matrix and for reception of ready briquettes.

line for turnkey trimmer

The advantages of this option include:

• Minimal labor hours to install the plant and high quality of such work.
• Elimination of buying “a pig in a poke”. high-quality new equipment will function better and longer without failures.
• In addition, modern technology is characterized by a longer service life, it is less energy-intensive, it will reduce the cost of manufacturing the final product.
• The high cost of such a project.
• No possibility of self-service, which respectively leads to downtime of the equipment even at minor breakdowns. This happens because the equipment is under warranty and service maintenance. As a result, even if the hose is torn, replacement of which takes about 20 minutes, you still need to call the specialists of the company, and it can take several days.

Homemade mini-press for the production of fuel briquettes

Do not rush to get rid of waste after construction and cleaning work, because sawdust, twigs, leaves and even dry grass can be excellent raw materials for manual production of fuel briquettes. And in order to start a full-fledged home mini-production, will have to take care and about the press for the manufacture of fuel briquettes, which can be made with their own hands from the available improvised means.

Stoves in homes can be heated not only by expensive coal, electricity and gas, but also by fuel briquettes, regular use of which helps to save personal money. Of course, you can buy such packages in ready-made form, using popular combined briquettes “Pini Key evrodr” (evrodrova) of oak, ash and other wood, but they will cost much more than products made with their own hands.

And if we consider that such raw materials are prepared from tirsi (sawdust) and other construction waste, it is better to switch completely to domestic production of briquettes at least to meet their own needs.

To date, manufacturers offer several types of machines for making briquettes from sawdust, toa and other waste, each of which has its own characteristics. For example, the universal briquette press labeled PB-1 is very popular, which is ideal for home production of fuel briquettes.

Nevertheless, the cost of such equipment is not affordable to all owners, and not always there is an extreme need to purchase professional machines for briquetting, because the raw material may not be so much, and in this case the cost of the press will not be justified. Naturally, this is not a reason to abandon the production of heating raw materials, which helps to save a lot of money, because if you want you can make a press for fuel briquettes with your own hands.

Thinking about what press for making briquettes will be the best for work at home, it does not hurt to get acquainted with the device and features of the most popular models of installations to date, so you can choose the best option. This list includes:

• The hydraulic press, which is the most budget-friendly and affordable of all existing presses. The low price of such equipment is due to the fact that the fuel packages made with its help are too loose and often break up into small fractions during combustion, not giving a strong and prolonged heat.
• Screw press for sawdust. Make with your own hands a design of this type is not so easy, because it has a fairly high level of complexity in the manufacture and involves the use of certain elements such as a screw, which resembles a steel spiral rod in conventional meat grinders. Nevertheless, all the efforts made are sure to pay off, as briquettes made on screw-type machines have a high density and the ability to burn for a long time.
• Percussion-mechanical type press is one of the most common types of design for homemade briquettes, as it is not too difficult to make. As for the finished product, the output is something in between the fuel pouches made on a hydraulic and auger machine.
• Press-granulator, which is used for processing mixed fodders. Such machine is also perfect for pressing raw fuel, but only a small fraction is used for its processing.

Organizing a home production for the manufacture of briquettes for heating, you should consider its potential capacity, the volume and characteristics of available materials to be processed by the press, as well as the availability of improvised means for the construction of a homemade machine. A detailed study of the pros and cons of different types of installations will also help to make the right decision.

Most often in households and small workshops are used hydraulic type presses, which can operate from an individual or a common (group) drive. As a rule, such devices have these advantages and disadvantages:

• Almost all construction waste can be processed in the hydraulic press, including wood, wood shavings and sawdust, plywood remnants, dry leaves, etc.
• Compared to other converting machines the hydraulic press has the lowest noise level during operation.
• High durability and reliability of design promotes maximum precision in feeding and almost instantaneous processing of raw materials, and some machines boast a speed regulator.
• The only disadvantage of this equipment is low density of briquettes produced.

That is, the hydraulic press is more suitable for those people, who are also engaged in woodworking industry and do not suffer from lack of raw materials. If there is not much material for making fuel briquettes, it is better to look at any other design, which will allow to make denser briquettes, capable of long and good burning.
