With clamp technology, the material is fed via a large hopper in which an agitator continuously transports the material to the transport screw. The screw transports a defined quantity into the pre-compactor tower, where the material is pre-compacted vertically into the compaction chamber bush. A hydraulic filling pusher then presses the material horizontally into the compaction chamber, which consists of two gripper sections at the top and bottom. The final briquette is formed in the pressing clamps by hydraulic pressure and ejected forwards with each cycle. This process ensures precise compaction and produces stable, long-lasting briquettes.

In die technology, the shredded material is fed into the chip container via a screw conveyor or manually. From there, a horizontal screw conveys a fixed quantity into the pre-compactor tower, which feeds the material vertically to the matrix. This is where the actual pressing process takes place: a large press cylinder with a press ram moves horizontally and presses the pre-compacted material against a stable metal wall behind the die. While the next pressing cycle starts, a pusher cylinder moves the die to create space for the next briquette. This technology ensures a consistently high briquette quality and is ideal for industrial applications with high throughput requirements.
