Pellet Granulators
CPM Pellet Granulators
The new generation of CPM Direct Drive (DD) granulators from Germany has been designed to pelletize even the most demanding materials under harsh conditions and within a limited footprint — while meeting all production standards. One of their key applications is wood pellet production.

Characteristics of CPM DD Pellet Granulators
CPM granulators are the world’s first pellet mills engineered specifically for biomass — including wood biomass — that use a direct-drive system, with no gearbox or belts. The high torque produced by the motors ensures excellent throughput while saving up to 20 percent energy compared with traditional drive systems.
Combined with the new steam-conditioning system, CPM granulators provide an optimal solution not only for biomass but also for classic feedstock materials, such as hulls and post-extraction meal in the oil-processing industry.
Advantages of CPM pellet mills:
– robust, durable construction
– direct drive (no gearbox, no belts)
– higher torque than traditional drive systems
– adjustable die speed with no torque loss
– excellent pellet quality and high PDI (Pellet Durability Index)
– easy quality control via sampling at the granulator door
– up to 20 percent lower energy consumption
– reduced operating costs and simple maintenance
– very short startup time
– smallest footprint in their class
– available with or without a control system
A major advantage of all CPM granulators is their modular design and their wide die-speed range (4 to 8 m/s) without torque loss. This ensures full compliance with even the most demanding pellet-production standards. CPM granulators deliver excellent pellet quality with high PDI values.
