[0002] Plastics refer to plastic (flexible) materials or rigid materials formed by curing and cross-linking, with high molecular weight synthetic resins as the main component and appropriate additives such as plasticizers, stabilizers, antioxidants, flame retardants, and colorants as the added ingredients. Mixing granules is necessary when processing polypropylene plastic products.

[0003] A plastic granule mixing device with announcement number CN207874610U can mix and shake plastic granules by setting a cylindrical mixing tank, a stirring motor and a stirring shaft.
