This kind machine is flat die pellet mill with three taper rollers, which is confirmed to the world market of renewable compression biomass energy demand.

The rollers adopts "Taper-shape" to make both ends line-speed consistent to die-inner and die-out, so it avoids dislocation friction between rollers and dies, so that the resistance is reduced, accordingly the energy consumption reduced, die's lifetime is enlarged. This is a significant difference between the similar compression formation machinery.

It can pelletize wood, straw, grass, stalk, weed, reed, any agro-waste and forest-waste.

It can also make animal manure, organic fertilizer etc. The capacity will be two or three times than making wood pellets.

The raw materials can be wood, straw, grass, stalk, weed, reed etc any agro-waste and forest-waste. It also can pelletize paper, rubber, plastic.
