WhatsApp: +86 18838072829Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually times the shell diameter (Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
WhatsApp: +86 18838072829An novel approach for determining grinding media system of ball mill was proposed. • The optimum media ball size of three size fraction samples were obtained. • The media size ratio was ascertained as φ 50 mm: φ 40 mm: φ 30 mm = 28%: 28%: 44%. • The installed power and productivity of ball mill ( Φ m × m) were calculated. Abstract
WhatsApp: +86 18838072829Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.

These rods run the length of the machine, which is most commonly between eight and sixteen feet in length. The diameter of these rods will range from, when new, between two and four inches. The rods are free inside the mill.
WhatsApp: +86 18838072829This review paper is mainly going to focus on the effect of grinding media on ball mill performance. Grinding media directly affects energy consumption, product size and consequently the grinding costs [11]. Proper selection of the grinding media reduces energy and material consumption in a ball mill. Different performances are achieved when
WhatsApp: +86 18838072829Tests by Coghill and Devaney show that the hardness of the balls has some effect upon the rate of grinding in mill. These results are plotted in Fig. and it is seen that, both for dolomite and chert, there is an increase in the rate of grinding with increasing hardness of ball.
