Grinding Pans

Grinding pans form one of the most ancient forms of mining machinery for grinding. They are used for sand grinding, mineral grinding and other similar grinding processes. They were also used to grind out impurities and they may vary in design but work on the same principle are used for batch grinding process.

Usually the pan is circular and set at an angle. It has a heavy ball inside and a spindle to let the sand in. As the pan rotates the heavy ball inside it near the bottom grinds the material to very fine powder. The earliest grinding pans and the bolls were of stone. Latter forms also use Iron and steel.
