rice husk pellet making machine adopts flat die design. The compression part is constituted by a press roller and a flat die. When you feed grinded rice husks into the pellet machine, they are distributed on the flat die. The roller put high pressure on the raw materials, and temperature inside rise up under high friction. There are many holes on the flat die, into which raw materials are pressed. When they are extruded from these holes, they are formed into cylinders, and cut into pellets of certain length.
