The production process of the plastic granulator is a process of making the polymer resin and various additives and auxiliary agents into granulated plastics through the processes of metering, bonding, plasticizing and granulating. Plastic particles are semi-finished products of the plastic molding industry. It is also a raw material for extrusion, injection molding, hollow blow molding, foaming, and other molding production. Many friends are very interested in how plastic granulators are produced. Shuliy Machinery introduces the production process of plastic granulators.

The production process of plastic granulator is as follows:
Waste plastic pretreatment classification, rough washing-washing-fine washing-drying, automatic feeding, plasticizing of the main machine, auxiliary machine extrusion, cooling, automatic granulation, bagging
The main machine of the plastic granulator is an extruder, which is composed of an extrusion system, a transmission system, and a heating and cooling system. According to the different working principles of each part, the plastic granulator works normally. Its system structure is as follows:
1. Extrusion system: The extrusion system includes a hopper and a mold. The plastic is plasticized into a uniform melt through the extrusion system. The extruder head is continuously extruded by a screw under a predetermined pressure.
2. The function of the transmission system is to drive the screw, which provides the torque and speed required during the screw extrusion process. It usually consists of a motor, a reducer, and a bearing.
3, heating and cooling device heating and cooling is a necessary condition for plastic extrusion processing.
