Grinding Mills. A common part of the reduction process is a grinding mill that takes grain sized materials that are larger than that which is required by a process and breaks them down to fine powder. Grinding mills are reduction machines that process materials into a finer form. They include rod mills, ball mills, and attrition mills.
