What Factors Will Influence Ball Mill Grinding Efficiency?
· Ball mill grinding efficiency is influenced by many factors: ore grindability, feed size, grinding product size, ball mill diameter and length, ball mill working speed, liner type, steel ball loading system, grinding concentration, return sand ratio in closedcircuit grinding and feed rate. (Ball mill) To improve the ball mill grinding efficiency, you must first understand the factors that ...
Ball Mills
Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter ( Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
