The processing temperature in the extruder is usually 120-250 ℃, the materials are in a melt in the extruder, the temperature reaches about 170 ℃, and the materials are used after being cooled, granulated and molded.
There are two general granulation methods, hot cutting and cold strand cutting. The hot cutting refers to the processes of granulating, cooling and forming, and the cold drawing and strip granulating refers to the processes of cooling, forming and granulating materials. And during hot cutting, the cutter is connected with the machine head, the material is immediately cut off and granulated by the rotating cutter after being extruded from the neck mold, and then is cooled by the water ring or the air ring, and then is dried and packaged in the dryer through the pipeline. And extruding the materials from a machine head die into strips during cold drawing and granulating, cooling the strips in a water tank with the length of 3-6 meters, drying the cooled strips by using a strong air dryer, and then drawing the strips to a cold drawing granulator for granulation and packaging. The cold-drawn strip granulation is simple in operation and low in cost, and is a current universal granulation method.

When the output of the extruder is lower than 400Kg/h, a cantilever supporting mode of a rubber compression roller, a traction roller and a cutter is generally adopted, and the granulator is opened from the side. The inside of pelleter is convenient for clear up. When the output of the extruder is higher than 400Kg/h, the number of the material strips reaches more than 30, and the width of the cutter (moving knife) must be increased to meet the requirement of the increase of the output so as to avoid influencing the quality of the cut pellets.
