Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

In this paper an effort is made to find optimum parameters for synthesizing nanopowders with ball milling. Vertical planetary mill with tungsten carbide (WC) grinding jar and WC balls were selected for performing milling operation. Rice husk ash (RHA) prepared in the laboratory by using muffle furnace was taken for milling. Very important grinding parameters such as milling speed, time of
The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm. 19904 rpm = ( 500 *1000) / (3.14 * 8) If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
