Crushers, grinding mills, and pulverizers are types of grinding equipment used to transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Grinding equipment can be classified into two basic types, crushers, and grinders. Industrial crushers are the first level of size reducer; further granularization occurs in grinding mills or pulverizers.
Answer (1 of 5): Crushing and Grinding are processes that work together to get the rock to be small enough so it can go to flotation. In flotation, they objective is to separate the valuable ore from the waste rock. Crushing is the initial stage of comminution (the action of reducing a material...
