Disadvantage Of Using Ball Mill In Coal Grinding. Exploring ball size distribution in coal grinding mills . It has been shown that mill capacity is linearly correlated to media surface area, thus using 30 mm balls as top size which leads to a fine ball size distribution in the mill is evidently a better approach than the current approach of using larger ball sizes.
About 27 to 35 % volume of mill is filled with grinding media. Equilibrium charge is that charge where compensation for wear can be done by balls of one size only usually the largest size in the compartment. Grinding media could be made of forged steel, cast steel or even cast iron.
Exploring ball size distribution in coal grinding mills. Small balls are effective in grinding fine particles in the load whereas large balls are required to deal with large particles of coal or stone contaminant The steady state ball size distribution in the mill depends on the topup policy
ball mill for coal grinding ball charge eduioncare. Exploring ball size distribution in coal grinding mills (PDF Download Tube mills use steel balls as grinding media. Due to wear in the abrasive environment it is necessary to charge new balls periodically to maintain a steady.
Coal mill is major equipment of cement plant and used for drying and grinding coal. The equipment mainly consists of feed device, main bearings, rotating parts, drive device, selling device, high-voltage start-up device and lubrication system. As the "black blood of industry", coal is usually ground into micro size powder, which can ensure ...
In doing so, the solid particles in between the balls and ground are reduced in size by impact. Applications. The ball mill is used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out either wet or dry but the former is performed at low speed.
