In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
Roll crushers crush material between two rolls or between a single roll and a fixed, flat plane. Grinding mills serve a wide variety of industries. In gristmills, for example, grinding mills are used to grind grains. Ball mills are commonly used to crush coal in power plants and to make black powder for pyrotechnics.
Basically, a grain mill takes grain or corn and mashes it up in order to produce flour. Even though you can use something as simple as grinding grain and corn between rocks, a grain mill makes it much easier to produce a useful and uniform flour. That being said, it may not be enough to have just one kind of grain mill on hand.
Generally for harder materials, specialized and expensive type of grinding mills are used. In addition if a particular mill can be used over a range of hardness scales, the harder the material the lower the throughput for a given size requirement.
