The horizontal ring-die pellet machine has a fixed ring die mold and rotating pressed rollers, and feeds the material from the top side. There will be no clogging or swelling for pressed fine animal feed. Because of its relatively fast rotation speed, it has a high production capacity for press fine feed pellets.
If pressing biomass materials, it requires a large compression ratio. The vertical ring die is a type of pellet machine model specially derived from biomass. The pressed rollers rotate and the ring die mold fixed. The material enters the pressing chamber and it is evenly thrown around the die mold holes, and pellets will be squeezed out from the die mold holes. It is very efficient for pressing biomass materials pellets.
