FM 306: SIZE REDUCTION AND SIEVING
2021-5-11 smaller size particles is much easier as compared to that of bigger particles. 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
