Industrial design for continuous operation.
Design parameters and performance data are defined according to the specific application.
Short description
Pellet presses are used for the continuous compaction of processed, free-flowing raw materials into dimensionally stable pellets. They represent a central process step in biomass processing and are used in industrial plants for the production of fuels, animal feed, or technical pellets.
The design of the pellet presses is application- and process-specific and covers a wide range of capacities – from compact units to large-scale industrial plants.
Principle
The conditioned raw material is continuously fed into the press chamber of the pellet press. There, it is guided by rotating press rollers against a die and pressed through the die bores under high pressure.
Due to pressure, friction, and temperature, the material undergoes plastic deformation, resulting in the formation of dimensionally stable pellets with defined geometry. The pellet length is adjusted by a downstream knife that cuts the emerging press strands.
The pellets leave the press at elevated temperature and are cooled and further processed in subsequent process steps.
Integration into the process
Pellet presses are typically integrated into the following process chains:
- after the size reduction and screening of the raw material
- after dosing and, if required, conditioning
- before cooling, screening, and conveying equipment
Integration is carried out either as a standalone machine or as part of a fully coordinated pelletizing line. A stable and uniform material feed is crucial for reliable press operation and consistent pellet quality.

Pellet presses at a glance
The pellet presses shown below are designed as industrial standalone machines or as part of complete process lines.
They differ in size, drive power, and output capacity and are each adapted on a project-specific basis to the intended raw material, the desired pellet quality, and integration into the overall process.
All press types shown are designed for continuous operation and can be combined with upstream conditioning, dosing, or size reduction units as well as downstream cooling and screening systems.
