On the basis of absorbing advanced technologies domestically and abroad, the machine group has adopted mosaic rotating roller. During working process, the press roller can be adjusted at will. And all functions have reached advanced world standard. The machine has forced material-entrance and overload protection device, which makes it work much safer. Modulator with large diameter has been used in this machine to make materials fully cured, and make the pellet smoother. The formation rate reaches 98% and the equipment wear rate has been fallen to the bottom. Speed-adjust feeding, adopted by this machine, can control the feeding capacity correctly to fit for different materials and meet the production requirement of pellets with different diameters.
