DR420 DR508 DR650 Ring Die Pellet Press Machine 6-12mm Pellet Size 1-3t/h Capacity PLC Control
Professional biomass and feed pellet production equipment designed for processing wood waste, sawdust, wood shavings, agricultural straw, rice husk, and various feed materials.
Raw materials enter the pelletizing chamber where the rotating ring die drives the roller shell. Through this mechanical action, materials are pressed through the ring die holes to form pellets, which are then cut to specified lengths.
