In a standard Bond ball mill with weight of material equivalent to 700 cm3. After every grinding cycle the mass of the minus 106 m fraction was replaced with fresh feed to keep the mass of the mill feed constant. This cycle was repeated until the net mass of minus 106 m material produced
The ball mill in closed circuit with hydrocyclones is an industry standard and well known methodologies exist for equipment siing selection and design.
The dia of ball is 12mm to 125mm. The dia of shell is 3m and its length is about 4.25m. The shell is rotated through a drive gear with speed 60100 rpm. that mill contains balls of various ages. Ball mill produces 1 to 50 tonhr of powder and energy requirement of the ball mill is about 16 kwhton.
This quantity is small compared to the power used by a semiautogenous mill and a ball mill in a primary grinding circuit a ball mill can have an installed power of up to 15 MW while installed power for a SAG mill can go up to 25 MW. However the energy used for fine grinding is still significant.

2019917Planetary ball mill is a most frequently used system for mechanical alloying since only a very small amount of powder is required. Therefore the system is particularly suitable for research purpose in the laboratory. The ball mill system consists of one turn disc turn table and two or four bowls.
