Automation contributes to plastic recycling granulators

With the upgrading of technology, plastic recycling granulator equipment has long ended the era of manual loading, people can be freed from heavy physical labor and dusty environment, the work done by humans is now automatically completed by conveyor equipment. Made a major contribution to the plastics industry.

In recent years, a large number of theoretical and experimental studies have been carried out on the screw. Up to now, there have been nearly 100 kinds of screws, and the common ones are separation type, shear type, barrier type, split type and wave type. From the perspective of single-screw development, although the single-screw plastic recycling granulator has been perfected in recent years, with the continuous development of polymer materials and plastic products, new types of screw and special single-screw extrusion will emerge. Granulator.

In all chemical manufacturing industries, plastic recycling granulators can be molded with various plastics such as pipes, films, materials, monofilaments, flat yarns, packing belts, extruded nets, plates, profiles, granulation, cable coating, etc. The auxiliary machines are matched to form various plastic extrusion molding production lines to produce various plastic products.

Plastic recycling granulators can be divided into single-screw, twin-screw and multi-screw extrusion granulators according to the number of screws. At present, the single-screw extrusion granulator is the most widely used, and is suitable for extrusion processing of general materials. The twin-screw extrusion granulator has less heat generated by friction, the shearing of the material is relatively uniform, the conveying capacity of the screw is larger, the extrusion amount is relatively stable, the material stays long in the barrel, and the mixing is uniform.

SJSZ series conical twin-screw extrusion granulator has the characteristics of forced extrusion, high quality, wide adaptability, long service life, small shear rate, difficult material decomposition, good mixing and plasticizing performance, direct molding of powder, etc. Self-control, vacuum exhaust and other devices. It is suitable for the production of pipes, plates, profiles and other products.

The single-screw extrusion granulator plays an important role as a plastic recycling granulation machine or a molding processing machine. In recent years, the single-screw extrusion granulator has been greatly developed. At present, the single-screw extrusion granulator for large-scale granulation in Germany has a screw diameter of 700 mm and a yield of 36 t/h.

In plastic extrusion molding equipment, the plastic recycling granulator is usually called the main machine, and the plastic extrusion molding machine that is matched with it is called the auxiliary machine. After more than 100 years of development, the plastic granulating extruder has been derived from the original single screw by twin screw, multi-screw or even no screw.

At present, China's plastic recycling granulator market is developing rapidly, and many new models are launched. Through the joint efforts of the industry's technology and R&D personnel, some major special types such as exhaust extruders and tandem discs are extruded. Machines, reciprocating pin screw extruders, foaming extruders, extruders with melt gear pumps, tandem multi-stage extruders, planetary screw extruders, etc. are produced in China and have independent The ability to develop and enjoy independent intellectual property rights.
