Briquetting is an efficient means of processing raw materials. Hunkeler Systeme's briquette presses can turn metal scrap and sawdust into highly heat resistant briquettes with excellent heating value.

A briquette press works at high pressures and is ideal for materials with binding properties at this pressure level, such as metal shavings contaminated by cooling lubricants from production processes.


Hydraulic briquette presses utilize the force of a pump or jack to apply pressure, with this pressure creating enough force to cause materials to bind together into solid blocks of fuel, such as wood or coal, that can then be used as firewood, charcoal or as an alternative fossil fuel replacement source. Briquetting also makes transport and storage of biomass materials much simpler.

Material required to build a hydraulic briquette press includes a bin, hydraulic pressure stand, feeding cylinder, master cylinder and clamping cylinder. The bin features a stirring device to ensure even and continuous feeding without jamming; its feeding cylinder works in conjunction with its master cylinder to compress material in multiple strokes for easier briquette assembly and less chance of dismantling.

An ideal material for creating briquettes is sawdust with a high wood density. However, to increase friability and calorific value without using too much moisture. If no sawdust dryer is available to you then drying can also take place during summer or in a ventilated room.

If your material has a low initial density, adding a briquetting agent may help boost it. Briquetting agents act like glue between particles when compressed together during compression; such agents include calcium carbonate or talcum powder as examples of such substances.

Before adding raw materials to a briquette machine, they should be cleaned to remove tramp metal, stand and concrete substances that could harm or reduce maintenance costs. A feeding cylinder equipped with sensors detects feedstock volume and can alert operators if insufficient feedstock quantity has been received.

GEMCO offers more than just briquette machines to densify biomass. For instance, its waste grinders can turn waste shavings into compact high-value briquettes with superior combustion performance than regular firewood or coal; making these an invaluable resource in furniture factories and saw mills.


Briquetting machines use heat to compress raw material into regular-shaped blocks that make transportation, storage and further use easier. Briquetting systems can handle materials of all sizes and moisture content levels; those requiring binder are equipped with heating systems so lignin melts to form high-performance binder binding material.

Briquetting involves feeding raw material through an agitator into a feed hopper. From there, it is transferred into a pre-compressor for compression before being transferred back into a main cylinder and finally pushing through into a die with multiple ejector holes where briquettes are produced.

Hydraulic briquetting machines employ hydraulic cylinders with much stronger specific pressure, which allow more consistent and dense briquette formation.

Hydraulic briquette presses are more precise, capable of maintaining stability for extended periods, which is especially crucial when creating briquettes from hard and abrasive materials. They also come equipped with intelligent liquid temperature control systems which detect when an oil overheats, activating cooling fans or electric heaters to regulate it and restore equilibrium quickly.

Energy can also be conserved with this machine by configuring an automatic shut off feature and safety switches that prevent starting the briquetting process until hydraulic piston has reached maximum stroke.

Briquetting systems can not only be environmentally-friendly but can reduce waste disposal costs while improving sustainability and profitability. A New Zealand company used a briquetting press to repurpose wood dust generated from its MDF production process into highly profitable and sustainable briquettes that could then be used in greenhouses for heating and lighting needs - providing both heat and light for heating needs as well as reduced deforestation!


At the core of my machine is a 300mm stroke hydraulic cylinder equipped with a 40 mm rod. Fractory provided me with laser cut mounting flanges designed specifically for my cylinder; then slowly welded them on to avoid deforming it. A feed tube made of seamless 40mm pipe was cut and fitted with laser-cut steel window and funnel parts; these monitor briquette production as two turns of the wheel equal about one meter produced - helping me estimate how many I could make per hour of operation.

When making briquettes, materials must be compressed under high pressure to densify them and then cooled to solidify their binder material - usually wood glue or urea. As this process requires considerable energy, the press needs to be designed accordingly in terms of power capacity and density adjustment for every raw material type used for production.

Home production of briquettes requires using a hydraulic briquette press. With its large capacity and power supplied from a hydraulic pump station, this option offers the most practical way to produce fuel briquettes. However, an hydraulic briquetting press may not be suitable when producing fuel with more than 50% organic matter content in its raw material.

Home hydraulic briquette presses may be constructed of materials such as steel, cast iron or aluminum to meet specific project needs and designed with safety features like door alarms, emergency shutoff and shutoff mechanisms and emergency shutdown capabilities.

The WEIMA TH Duo hydraulic briquetting press is an efficient hydraulic press designed for seamless integration into existing systems, producing rectangular 150x60 mm briquettes at high throughput rates. Equipped with both flexible filling capabilities and a compact material buffer for continuous, mostly automated operations, the TH Duo can also come complete with metal detectors for separation of nails or screws from its output material.


briquetting machine. For this reason, its main component - the briquette press - should be designed to withstand high pressure without breaking or losing its shape, making steel with at least 4- to 5-mm wall thickness an optimal material choice. Furthermore, its lever attachment should have an indented protrusion at its end to enable several strokes without dismantling during its use.

Hydraulic briquette machines utilize the force of a piston to compress raw material and form it into briquettes, providing an ideal way to convert waste wood into fuel more efficiently and environmentally-friendly than regular firewood. Furthermore, the briquettes can be used in stoves or fireplaces as an alternative fuel source with improved combustion properties than traditional sources.

Briquette presses require energy, but can be tailored to meet the specific requirements of individual facilities. For instance, if large volumes of sawdust need to be processed into briquettes then investing in a larger capacity machine could be advantageous.

Briquetting machines have many applications within the metal industry, including making aluminum briquettes that can be highly beneficial in industrial furnaces, serving as replacement fuel and being easier to transport than wood shavings.

Briquetting machines offer another key benefit for countries with tropical climates: their ability to reduce deforestation. By recycling wood waste from pineapple fields into renewable, carbon-neutral fuel that's cheaper than firewood or coal purchases, briquetting machines help mitigate forest clearing while simultaneously increasing profitability for businesses.

Briquetting machines provide an effective method for manufacturing companies to convert waste wood byproducts into an economically sustainable product that can be sold as biofuel. One company in New Zealand successfully used their dust byproducts from MDF production as biofuel to earn significant profit. Furthermore, the briquetting process removes cooling lubricants from chips so they are suitable for recycling at their original manufacturer's plant or returned back for reuse as an added advantage.
