Briquetting presses – find manufacturers and suppliers

Briquetting presses play a central role in waste recycling, energy technology and raw material processing by pressing loose, fine-grained or powdery materials into solid, manageable briquettes under high pressure.

Their use offers ecological and economic advantages: Less space required, lower transportation costs, increased material value creation and a better environmental balance due to recycling and reduction of emissions.

Below you will find an overview of how briquetting presses work, the types and uses of briquetting presses, as well as a brief overview of their advantages:

How briquetting presses work:

The central function of the briquetting press is to compact the source material - for example metal shavings, wood waste, paper, peat, coal fines or biomass - without the addition of binding agents by means of purely mechanical or hydraulic pressure.
Compaction takes place in a press chamber, where pistons, rollers or screw mechanisms press the material together.
Depending on the type of press (mechanical, hydraulic or with eccentric technology), different forces and types of movement are used.
The aim is to increase the density of the material, improve its storage and transportability and process it for further use (e.g. as fuel or raw material).

Types of briquetting presses:

Briquetting presses differ mainly in terms of their drive technology, the pressing mechanism and the type of material processed. Each of these briquetting presses has its own specific strengths and areas of application.

1. Hydraulic briquetting presses:
   Press the material against a mold or die using a hydraulic cylinder.
   High pressing pressure, compact briquettes, well suited for fine or sensitive materials.
   Typical areas of application: Metal chips, dust, biomass, mixed materials.
2. Mechanical briquetting presses:
   Use a flywheel or eccentric to build up mechanical pressure quickly and repeatably.
   High cycle rate, ideal for large quantities with uniform consistency.
   Typical applications: Wood chips, coal dust, low moisture biomass.
3. Screw presses (exzuder presses):
   A rotating screw continuously conveys and compacts the material into a nozzle.
   Continuous operation, ideal for moist or fibrous biomass such as rice straw or peat.
   Typical applications: Biomass, organic residues, straw, paper.
4. Roller presses (roller presses):
   Two counter-rotating rollers with dies shape the material into briquettes as it passes through.
   High production output, various shapes possible.
   Typical applications: Coal, fertilizers, minerals and mixed materials.
5. Stamp presses (piston presses):
   A ram (usually hydraulically or mechanically moved) compacts material in the cylinder.
   Robust technology, good for dry wood chips and similar materials.
   Typical areas of application: Wood and biomass.

Use of briquetting presses:

Briquetting presses are used in many industries:

1. Wood and biomass industry:
Sawmill waste, wood chips or agricultural residues such as straw or husks are processed into fuel briquettes.
These briquettes serve as an environmentally friendly, CO₂-neutral heating alternative.

2. Metal processing:
Metal shavings, e.g. from aluminum, steel or cast iron, are pressed into dense briquettes.
This reduces the volume and enables a more efficient return to the recycling cycle or smelting processes.

3. Waste management:
Paper, textile or plastic waste can be briquetted for space-saving storage, transportation or thermal utilization.

4. Mining and coal industry:
Fines from coal or ore that would otherwise be difficult to use are compacted into briquettes that can be stored and transported.

Advantages of briquetting presses:

• Volume reduction: Loose materials are highly compacted, which significantly reduces storage and transportation costs.
• Recovery of valuable materials: Valuable raw materials can be recovered and efficiently recycled, especially in the case of metal shavings.
• Improved handling: Briquettes are dimensionally stable, dry, easy to stack and easier to dose than loose chips or dust.
• Better environmental balance: Less waste, lower emissions and often CO₂-neutral fuels, e.g. from biomass, promote sustainability.
• Safe transportation: Solid briquettes reduce dust formation and explosion risks when transporting fine materials.
• Cost-effectiveness: Briquetting not only saves space, but can also generate additional revenue through the sale of briquettes (e.g. metal or fuel).

The use of briquetting presses offers ecological and economic advantages: less space required, lower transportation costs, increased material value creation and a better environmental balance through recycling and reduction of emissions.

Here you will find an overview of the most important points to consider when purchasing briquetting presses:

There are numerous technical, economic and operational factors to consider when purchasing briquetting presses. Choosing the right machine not only influences the productivity and quality of the briquettes, but also the cost-effectiveness and sustainability of the entire process.

• The most important factor is the material to be processed: wood, biomass, metal shavings, paper, plastic, peat or coal dust all place different demands on the press.
• Properties such as grain size, moisture, flow behavior, abrasiveness and thermal behavior determine whether a hydraulic, mechanical or screw press is suitable.
• consider how many kilograms or tons of material are to be processed per hour. The briquetting press must be suitable for the production volume without being oversized. The operating time per day, possibly in shifts, also plays a role in the selection.
• Hydraulically operated presses usually work more slowly, but deliver high density and flexibility in the material. Mechanical presses are suitable for large quantities of consistent material, but are usually less tolerant of moisture or particle fluctuations. Screw presses can work continuously, but require more energy and maintenance.
• Depending on the intended use, certain briquette shapes are required: cylindrical, rectangular, with or without a hole (for better combustion), etc.
• Make sure that the press can produce the desired shape and density.
• For fuel briquettes, uniform quality is particularly important, while for metal, density and recoverability are paramount.
• Modern briquetting presses offer various automation options - from manual feeding to fully automatic lines with conveyor system, cooling, packaging and control.
• The degree of automation should match the company size and personnel capacity.
• A robust machine concept with a good spare parts supply and easy access to wear parts, e.g. press cylinders, seals and knives, reduces long-term operating costs.
• The availability of good customer service, training and fast technical support are also crucial.
• Energy consumption, lubricant requirements, cooling and maintenance cycles have a significant impact on running costs.
• When purchasing, look out for energy-efficient drives and integrated energy-saving functions where applicable.
• Briquetting presses operate at high pressure and temperature. The machine should have CE marking, an emergency stop switch, protective covers, temperature and pressure sensors and automatic shutdown in the event of a fault.
• The press should be able to be integrated as seamlessly as possible into existing systems - both mechanically into the existing conveyor systems and storage as well as in terms of control technology, e.g. PLC systems
• Space requirements and connection values for electricity, hydraulics and cooling must also be taken into account.
• In addition to the purchase price, the purchasing department should consider the total costs over the life cycle: Energy consumption, maintenance, downtimes, personnel costs, possible proceeds from the sale of the briquettes, subsidies or tax benefits, e.g. for CO₂-neutral energy. A careful amortization calculation helps with the investment decision.
• An established manufacturer with good references usually offers more reliable machines and better service.

The purchase of briquetting presses is a strategic investment that goes far beyond the machine price alone. A precise analysis of the source material, the right technology for the desired briquette quality and economically sensible dimensioning are crucial for success. Those who also pay attention to energy efficiency, automation, ease of maintenance and a reliable manufacturer create the basis for smooth operation and long-term profitability.
