Background

Plastic particles are the common name for plastic granules, and are the raw material for storing, transporting and processing plastic in the form of semi-finished products. Plastics are a kind of high molecular material, and can be used to prepare ethylene, propylene, vinyl chloride, styrene, etc. by using petroleum as raw material, and the molecules of these substances can react with each other under a certain condition to produce compounds with very large molecular weight, i.e. high molecules. With the continuous development of science and technology and the progress of society, the application of plastics is more and more. Plastic products are widely used after development, and since plastic is hardly decomposed by minute molecules, it is recovered after use and processed for recycling. After the plastic product is recycled, the plastic product is crushed and processed, the size of part of particles of the crushed plastic is different, and the crushed plastic particles need to be screened and crushed again.
