Ball mill reduces feed size mainly by

8.3.2.2 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

    Dec 24, 2020 In ball mills, we are using metal balls as grinding material. Here half of the shell is filled with balls and feed material is fed with it. Now, due to rotation of shell, the metal balls will be taken to top with shell wall and from there it will fall and cause attrition and impact and reduces the size of

    Feb 08, 2017 For efficient operation of ball mills necessary to observe the right balance between balls size and feed material size. If the feed material contains many large lumps and grinding balls can’t crush them, it leads to a gradual accumulation them between the balls. As a result, mill suspends own operation. In these cases, need to reduce the size
