Liners Ball mill ends usually have ribs to lift the charge with mill rotation These prevent excessive slipping and increase liner life They can made from white cast iron alloyed with Ni hard and rubber Drum Feeders The entire mill feed enters the drum via a chute a spout and an internal spiral carries it into the trunnion liner The drum also provides a convenient methods of adding
charge should always be 50 material charge will vary from 25 to 40 or more in some cases such as when grinding 100 homemade airfloat charcoal The best way to tell if your mill is properly charge is to listen to it after about 15 minutes of grinding You should hear a continuous cascading sound that is fairly loud If the mill seems quiet
More balls with small size results in fine powder As a thumb rule powder to be milled should be taken as 25 of total ball weight If the quantity of charge is very less then milling balls will
