    How it Works: Crushers, Grinding Mills and Pulverizers

    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 to two basic types, crushers and grinders. Industrial crushers are the first level of size reducer; further granularization occurs in grinding mills or pulverizers.
