GROSS GP 80 Briquette Press

GP 80

Briquette press with clamping technology

For the skilled trades and industry

The GROSS GP 80 is a robust briquette press designed for medium throughput requirements in wood-processing plants. It compresses wood shavings, sawdust and other homogeneous waste materials without the use of binders into compact briquettes with a diameter of 50 mm, achieving a throughput of up to approximately 80 kg/h, depending on the material. The briquettes can be stored in a space-saving manner and used to generate heat in suitable heating systems. A PLC control system enables fully automatic operation.

Technical specifications

The material is fed in via a large hopper and conveyed by an agitator to the briquette press’s feed screw. The screw conveyor transports a specified quantity into the pre-compactor. A hydraulic feed gate then pushes the material into the press clamp, where it is compressed under high pressure into a solid briquette. With each pressing cycle, the finished briquette is pushed a little further out of the machine.
