[0002] Plastics are polymer compounds that are polymerized from monomers through addition polymerization or condensation polymerization. They are commonly known as plastics. They can freely change their composition and shape. They are composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. They can be widely used in chemical, aerospace, military, family, hospital and other fields, and have good promotion value and social benefits. Plastic crushers are mainly used to crush various plastic plastics and rubbers such as plastic profiles, tubes, rods, wires, films, and waste rubber products, crushing these plastics into granules, and then using these granular pellets as the production principle for extrusion molding.
