Briquetting systems – find manufacturers and suppliers

Briquetting systems are industrial systems that collect and process loose, fine-grained or powdery materials in order to compress them into solid briquettes using mechanical or hydraulic pressure.

The aim is to convert unwieldy or difficult-to-process raw materials into a stable, transportable and storable form. Such systems are used in many industries - from metal processing to the wood and biomass industry to waste management.

Below you will find an overview of how briquetting systems work and how they are used, as well as an overview of their advantages:

How briquetting systems work:

Briquetting systems typically consist of several components that vary depending on the type of material, production target and degree of automation.
The central component is the briquetting press, which forms the material into the desired briquette shape under high pressure.
Binding agents are usually not used - compaction is purely mechanical or hydraulic.

1. First, the raw material is fed into the pressing system via conveyor belts, hoppers or screws.
2. Drying or shredding may be necessary before the pressing process, especially in the case of moist biomass or coarse metal shavings.
3. The material is then fed through a pressing chamber in which it is heavily compacted.
4. The pressing system can be operated hydraulically, mechanically, with pistons, rollers or screws, depending on the type of system.
5. The resulting briquettes are automatically ejected, cooled and packaged or stacked as required.
6. Modern systems integrate sensors, control technology and quality assurance to ensure continuous, safe and energy-efficient operation.

Use and areas of application of briquetting systems:

Briquetting systems are used wherever large quantities of residual materials, chips or fines are produced that would otherwise be difficult or expensive to dispose of - or can even be used as a valuable secondary raw material.

1. In the wood and biomass industry:
Here, briquetting systems are used to convert sawdust or wood shavings, wood chips, straw, rice husks, nutshells or other plant residues into heating briquettes.
These briquettes replace fossil fuels in heating systems or industrial furnaces and are considered CO₂-neutral.

2. In metal processing:
Briquetting systems help to press metal chips, such as those made from aluminum, steel or cast iron, into compact briquettes that are easier to store and transport.
They can be fed back into the production cycle, for example in foundries or melting furnaces.
Briquetting also promotes the recovery of cooling lubricants.

3. In the waste management and recycling industry:
Briquetting systems are used here to reduce the volume and process plastics, textile waste, paper, sewage sludge or industrial waste. The compacted materials can be better disposed of, thermally recycled or even further processed.

In the coal and mining industry:
Fine fractions of coal, peat or ore, which would normally be considered waste, are converted into storable, energy-rich briquettes by briquetting, which can be used directly in industrial processes.

Advantages of briquetting systems:

• Loose chips, dust or residual materials are highly compacted, which reduces the volume by up to 90 % in some cases. This saves space during storage and significantly reduces transportation costs.
• Materials such as metal shavings, biomass or coal residues, which would otherwise be considered waste, can be converted into recyclable briquettes - for reuse, sale or energy recovery.
• Briquetted material is easier to store, sell or process. In many cases, briquettes achieve higher market prices than loose materials. In addition, disposal and waste treatment costs can be significantly reduced.
• Briquettes are clean, dimensionally stable and generate less dust or contamination. They are easier to transport, dose and store than loose, fine-grained or fibrous materials.
• The use of residual materials (e.g. wood waste, organic biomass) as fuel replaces fossil fuels. At the same time, CO₂ emissions and the ecological footprint of production are reduced.
• In the metal industry, cooling emulsions or lubricants can be pressed out and reused when briquetting chips. This saves costs and protects the environment.
• Biomass briquettes have a defined calorific value, a uniform shape and often less moisture. This ensures clean, efficient and controllable combustion.
• Briquetting systems allow waste to be fed back into the production cycle as material or energy. This promotes the sustainable use of resources and complies with environmental regulations.
• Modern systems can be fully automated and integrated into existing production lines. This saves on personnel costs and increases operational safety.

Briquetting systems are versatile, resource-saving systems that create new recyclable materials from supposed waste. Their mode of operation is based on the physical compaction of a wide variety of materials without chemical additives. The choice of the right technology depends on the source material, the desired briquette quality, the production volume and the operational infrastructure. Used correctly, briquetting systems reduce disposal costs, improve logistics, increase material value and actively contribute to a more sustainable industry.

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

When purchasing briquetting systems, a careful analysis of the technical requirements, material properties, production targets and operational framework conditions is essential. The investment is usually long-term and has a direct impact on production costs, material efficiency and environmental balance.

• The first and decisive question is: What should be briquetted? Depending on the material - whether metal shavings, wood residues, biomass, paper, plastic, coal fines or mixed waste - the requirements for the briquetting technology vary greatly.
• Influencing factors include particle size, moisture content, density, abrasiveness, flash point and any admixtures.
• Some materials require pre-drying, crushing or even special safety measures, e.g. for explosive dusts.
• Depending on whether the briquettes are to be used for energy recovery, sold, temporarily stored or recycled, the requirements for pressing pressure, density, briquette shape and homogeneity change.
• Fuel briquettes, for example, require a uniform shape, defined residual moisture and good combustion properties.
• Metal briquettes, on the other hand, should be as compact as possible in order to optimize transport and melting properties.
• The design of the system must match the daily or hourly material quantity. Not only should the current demand be taken into account, but also possible increases in production.
• An oversized system drives up investment and operating costs unnecessarily, while an undersized one leads to bottlenecks, downtime or overloading.
• Depending on the material and area of application, different technologies can be considered: hydraulic presses, mechanical presses, screw or roller systems.
• Hydraulics are suitable for high pressing pressures and variable materials, while mechanical systems are faster and more economical with uniform input.
• Screw presses are often popular for biomass, but involve higher maintenance costs.
• Each technology has advantages and disadvantages that must be tailored to the specific application.
• Modern briquetting systems can be fully automated - from feeding and briquetting to packaging or storage.
• To ensure efficient production, it is important to check how well the system can be integrated into existing processes, control systems such as PLCs and conveyor technology.
• Remote monitoring, fault diagnostics and interfaces for Industry 4.0 applications are also relevant criteria today.
• In addition to the purchase price, the ongoing operating costs are decisive for economic efficiency. These include power consumption, maintenance costs, lubricants, personnel requirements and downtimes.
• An energy-efficient system with low wear significantly reduces the long-term overall costs.
• A low-maintenance design, easy access to wear parts and good availability of spare parts are important.
• Long downtimes due to hard-to-reach components or missing spare parts can be expensive.
• Also look out for training opportunities for operators and maintenance staff.
• The system should comply with current safety standards, e.g. CE marking, emergency stop systems, protective covers, temperature and pressure monitoring.
• Comprehensive safety concepts are required, especially when processing flammable or explosive materials, such as ATEX approvals or extraction systems.
• In many companies, input materials, batches or input materials change. A good briquetting system should be able to cope with different materials or be quickly adaptable, for example through exchangeable dies, adjustable pressing parameters or modular additional functions.
• Rely on experienced, established manufacturers with a good reputation, long-term availability of spare parts and technical support.
• Experience reports, reference projects and visits to existing customers can provide valuable insights.
• Ultimately, a profitability analysis should be carried out, taking all factors into account:
• Investment costs, operating costs, potential revenue from briquette sales or raw material recovery, savings on disposal and logistics as well as any funding opportunities for energy efficiency or recycling measures.

The purchase of briquetting systems should be based on a well-founded needs analysis and, in addition to technical performance, also take into account maintainability, energy efficiency, safety and integration into the overall process. Paying attention not only to the purchase price, but also to long-term operating costs and flexibility, lays the foundation for economically successful and sustainable use.
