1. Big ones have 3-4 taper rolles, our patent product. 2. Biomass energy pellet. Animal feed pellet. Fertilizer pellet. 3. Biomass energy pellet diameter is 2-10mm 4. Briquette diameter is 15-25mm 5. High output, low consumption. Easy operation. The pellet mills adopt the Germannic advanced pellet pressing technology and we invent the tape-shape roller serise with flat dies mill. They can make pellets(2-10mm), briquettes(15-30mm), bircket(20*30mm)by changing the dies, which are widely applicable to the crude fiber materials: Sawdust, rice hust, cotton stalk, cootton seed hull, weeds and all kinds of crop straw, home wastage, the worn out plastic and the factory reject, the material of low adhesion rate, difficult to forming. It also can be applied to biological fertilizer, organic fertilizer, compound fertilizer low temperature pelleting.
