The Graf GEPD 900/138 “Gorilla”: The world’s first biomass pellet mill with direct drive motor

The Graf 900 Series “Gorilla” Pellet Mill is a first of its kind in every way, while continuing to build on Graf’s long experience in pellet mill manufacturing. The new direct drive pellet mill features variable die speeds, allowing the operator to control the pellet quality through variable moisture and particulate size events. This mill has no belts or gears, so it needs less maintenance. The high torque motor is directly connected to the drive motor to deliver the power directly to the pelleting chamber.  

While the motor assembly technology is new, the pelleting chamber features Graf Equipment’s tried and true signature robust and compact design. The mill features a temperature sensor at the roll assembly, and available with optional control systems, feeders, mixers, die and roller lifts.
