Volume and size reduction is an important factor in the development and operation of any SWM system. The main purpose is to reduce the volume (amount) and size of waste, as compared to its original form, and produce waste of uniform size.
Many particle size measurements are made to track size reduction operations such as milling, mixing, homogenizing, etc. The size reduction unit operation is performed under set conditions or for a required time frame until a specified size is achieved. The choice of particle size analysis technique can be based on the size distribution of the input, output, or both.
