Bal-tec Ball Material Selection

Chrome alloy steel balls comprise about 90% of all balls manufactured. This material is a high carbon (1.00%), chrome (1.36%) alloy steel that will harden into the 60 65 HRC range when oil quenched from a soaking temperature of 1475 ° F. The hardness usually ends up at 62 HRC. The stress relieving or drawing temperature is 325 ° F.

Ball Mill: Operating principles, components, Uses

The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
