Ball Mill: The equipment to be used for size reduction is ball mill. The ball mill is kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse material charged along with the metal balls breaks to fine powder by impact of metal balls. 1
Batch Laboratory Ball Mill. The (Open) Batch Mill makes possible simulation of grinding in a ball millclassifier circuit by grinding a fixed time, then hand classifying with a sieve and a bucket and returning the sand to the mill for further grinding. Pulp volume can be kept at a minimum by control of wash water since the ball load does not dump out.
