In plastic reprocessing after the types of plastic separated is a Mechanical processing to run the plastic through the Pulverizer. Pulverizer or Pulveriser crushes the plastic into tiny shreds or granules. Plastic pulverizer is the particular equipment for recycling disused insignificant materials in producing and grinding heat-sensitivity plastic such as PVC.
Pulverizer includes high output units which can be equipped with automatic temperature control. The material to be pulverized is fed centrally between a fixed and a high speed rotating pulveriser disc with centrifugal effect carrying the material through the processing zone before being discharged from the machine pneumatically.
Several different types of pulverizer machines are used to smash down other materials, such as rock, glass, wood, metals, and cement. When it comes to plastic, the three primary types of pulverizers are granulators, shredders, and ring mills.
A granulator operates thousands of evenly spaced blades in order to shred or granule the plastic into finely pulverized objects. After it is pulverized, it can be melted and reformed.
A shredder is similar to a granulator in that it contains evenly spaced blades, though these blades cut the plastic into strips. Some cut both vertically and horizontally in order to produce square shaped plastic pieces.
A ring mill, on the other hand, has a large, steel rolling blade. This blade chops and grinds the plastic that is placed inside the roller. After it has been ground up to the desired size, it falls through the small holes located beneath the rolling blade.
