The operation of used plastic pulverizers, or mills, is very simple. A serrated grinding disc rotates at a high speed against an identical stationary disc. When the plastic product to be reduced is placed in the pulverizer infeed, the size of the origanal product can be reduced to a powder. The size of the final powder can be determined by adjusting the gap between the discs. Arlington's list of current pulverizers is below.
