design features of ball mills. Ball Mill - an overview ScienceDirect Topics . A feature of ball mills is their high specific energy consumption; a mill filled with balls working idle consumes approximately as much energy as at full-scale capacity i.e. during grinding of material. Therefore it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following ...

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.

Ball Mill - an overview ScienceDirect Topics

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.
