size reduction of solids crushing and grinding equipment. abstract the unit operation of the size reduction or comminution of solids by crushers and mills is a very important industrial operation involving many aspects of powder technology. it is estimated that mechanical size reduction of rocks, ores, coals, cement, plastics, grains, etc.
size reduction by crushing has a size limitation for the final products. if further reduction is required, below 5- 20mm, grinding processes should be used. grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition.
pin mills are used to reduce the size of medium- to low-density materials such as talc and clay. pin mills use centrifugal forces to smash large particles against pins. equipment design a colloid mill rotor is an intermeshing rotor used for the size reduction of materials by multiple impacts with the maze of pins.

size reduction is mainly done through crushers and mills. crushing and grinding are the two primary comminution processes. crushing is normally carried out on the "run-of-m ine" ore. the g rinding
grinding is generally considered reduction to table salt size, or about 5 to 25 mesh. pulverizing for instance, if you need coal, grain or other minerals to be in powder form, you would run them through a pulverizer or a roller mill.
colloid mills are basically achieving a size reduction by submitting the product to intense shear forces created by a high speed rotor. the rotor is in a housing, by introducing the product in it, the rotor is creating a high that will ultimately break the particles.
