In the entire beneficiation process of a concentrator, grinding operation cost accounts for a considerable proportion. The grinding fitness is one of the main factors affecting the mineral processing index，which will directly affect both the grade of concentrate and the recovery rate of product. Therefore, how to improve grinding fineness of the ball mill becomes an important part of controlling grinding operation cost.
Ball mill is a key mineral processing equipment that used for grinding after the crushing stage. According to the different modes of ore discharging, the ball mill can be divided into grid type ball mill and overflow type ball mill. But do you know what are the similarities and differences between these two kinds of ball mill?
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 closed-circuit grinding and feed rate.
