Category: Pellet mills

The new generation of German Graf Equipment GmbH Gorilla pellet mills is especially designed for applications with very hard pelleting conditions in terms of raw material quality in limited working space and while keeping all production norms. The production of wood pellets is one of these applications.

In fact, Gorilla is the first pellet mill designed for the biomass industry, including wood biomass, with direct drive system, without gearbox or V-belts. The new pellet mill performs a high efficiency thanks to its powerful torque motor, saving around 20% of energy, compared with the conventional drive systems.

Gorilla pellet mills in combination with the new Graf Equipment GmbH steam conditioning system forms also an optimal pelleting line for classical feed products as well as for hulls and extraction meal in the seed oil industry (extracting seed oil).

An unquestionable advantage of all Gorilla pellet mill is their modular design and a large die speed range (from 4 to 8 m/s) without loss of torque, which allows to meet even the highest technological standards of pellet production. Gorilla pellet mills assure superior finished pellet quality with a high PDI (Pellet Durability Index).
