Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can

The electric power supplied to the device sets in motion the ball and the powder that it contains. The kinetic energy supplied in this way is consumed in the grinding process, but a large amount of power is dissipated by friction between the different mechanical parts of the device and through Joule effect in wires.
