Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
DOVE Ball Mills are size reduction machines, designed for grinding applications, where fine material is required. Applicable for wet and dry grinding applications within the following branches of industries: Mining Construction Waste Processing Food Processing Chemical Pyrotechnics Ceramics and etc.
The choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the ...
