Inside the plastic machinery industry, granulator is one of the important, granulator in chemical industry are widely used in melting point (softening point) in less than 300 ℃, condensing granulation of various materials. Such as sulfur, paraffin, rosin, asphalt, partial acid, stearic acid, maleic anhydride; Phenolic resin, petroleum resin, modified resin and other resin products; Hot melt adhesive, urea, synthesis soap, additives, rubber and plastic additives and other products.

Most of the polymer before make the final product, must cooperate with mixing, granulation, then become to sales of raw materials. Required amount of power and extrusion granulator is proportional to the relationship between index with mesh size. There are many different granulating machine design, but all granulation can be divided into two categories: the surface of cold pelletizing system and eagerly
