A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace.
