### Ball Mill Parameter Selection & Calculation - Power ...

Aug 30 2019 The wear of drop steel ball is related to its impact force. The wear of grinding steel balls is related to the surface area of steel balls. In general the steel ball in the grinder has both impact and abrasion effects so the wear is proportional to the n power of the diameter of the steel ball and the value of n is between 2 and 3.

Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include: Speed of mill rotation; Mill diameter; Mineral density;

### Grinding - Mineral Processing

Ball mills produce fine particles with a uniform size for flotation its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore as the ore grinds these balls initially 5-10 cm in diameter but gradually wear out. Grinding is always carried out under wet conditions with about 70 solid mixture in water.
