Effect of grinding media on the milling efficiency of a

ball mill employs steel balls to generate a grinding ac-tion, i.e. ore particle comminution via impact and abra-sion with steel balls, and is a key component of benefi-ciation plant production. Even though it has massive benefits, such as a high reduction ratio, effective break-age impact, and a wide application (Fuerstenau and8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.Ball Mill an overview ScienceDirect Topics
