A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
Overloading of the mill leads to accumulation of fines at the toe of the mill, which result in cushioning effect on the balls upon impact. Contrarily when the material load is low, excessive ball to ball contact retard the rate of
Ball mill is the most common equipment in the beneficiation equipments. The amount of the ball load can not only affect the grinding efficiency and productivity, crusher for gold mining but also affect the using life of ball mill.
In wear-resistant steel ball grinding, in the condition of the same grinding fineness, grain size more coarse, the ball mill production ability is lower; Feed particle is smaller, it has a higher production capacity.
Effect of Ball Diameter, or Rod Diameter Variation The first relationship to be considered is the effect of the variation of the ball diameter, or rod diameter, upon the size distribution obtained. In Fig. 6.1 are shown typical size frequency curves obtained by ball milling; these curves being deduced from the data of Coghill and Devaney.
Effect of ball diameter size on mill power draw The mill power draw for each mill run was determined from the voltage required by the mill motor average voltage and torque.
Ball mills give a controlled final grind and produce flotation feed of a uniform size. ... The net effect is that tumbling milling media are accelerated within the mill chamber, not by gravity, but by the centrifugal force created by the spinning central platform.
