Ring die pellet mill working principle

Ring die pellet mill or wood press machine, were invented at 1930s. The compress roller of ring die pellet mill is a cylinder wall with many hole, it depends on driving motion to rotate. Each ring die pellet mill contains 2-4 free rotating rollers and they are driven with grooves. The raw material goes into the feedstock and enters the pelletizing chamber. While the roller rotates, the material is pressed into the holes of the ring die and then, after cutting, there are pellet mills. Main character of ring die pellet is the same surface speed of ring die and compress rollers. Because of that there is no extra friction force and all the compress force is being use to make pellets, so, the ring die pellet mill is very efficient and can process hard materials like hardwood.
