Coal Ball MillCoal ball mill is the equipment used for grinding and drying coal with different hardness. It is mainly composed of feeding device, principal axis, rotating part, transmission part, discharging part, high-pressure starting device and lubrication system.
Spherical grinding media are predominantly used in final stages of ore grinding. The spherical balls change shape through breakage and wear. Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill power is not fully established. One area that is usually ignored is the relationship between

The grinding jar is arranged eccentrically on the sun wheel of the planetary ball mill. The direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2.
This change in the circulation regime of mill charge, and hence the grinding performance, should be reflected by an accompanied change in mill power consumption. As a first step, information was obtained on mill power draw as a function of grinding time and slurry density. Dimensions of the batch ball mill used are given in Table 1.
