the ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 11.5 times the shell diameter .the feed can be dry, with less than moisture to minimize ball coating, or slurry containing 2040% water by weight.
types of ball mill: wet grinding ball mill, dry grinding ball mill, horizontal ball mill, vibration mill, large ball mill, coal mill, stone mill grinder, tumbling ball mill, etc. the ball mill barrel is filled with powder and milling media, the powder can reduce the balls falling impact, but if
nov 01, 1985 effect of chemical additives on the dynamics of grinding media in wet ball mill grinding. int. miner. process 251--287. recent papers on the role of grinding aids in wet ball mills indicate that certain poly- meric aids favorably act by altering pulp rheology, leading to improved production rates at high pulp densities.
maintain the coorstek media charge at 48%-55% of total mill volume in batch-type mills and 38%-42% in continuous mills. In most cases, production efficiency decreases and wear of the media increases rapidly if the level of the media charge is allowed to drop below these recommended amounts, or if the media are not properly covered with material.
