wet grinding mills is mainly used for separation of gold, silver, lead, zinc, molybdenum, iron, copper, antimony, tungsten, tin and other minerals selected. with less investment, fast results, small footprint saving power, sturdiness and durability, ease of maintenance and high return on investment. It is the preferred production for alternative ball mill, is ideal for small and medium grinding mills ore capacity. the isamill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills stirred mills often consist of stirrers mounted on a rotating shaft located along the the sag mill was designed to treat 2,065 of ore at a ball charge of volume, total filling of 25% volume, and an operating mill speed of 74% of critical. the mill is fitted with mm grates with total grate open area of 7.66 4.5 diameter by 5.2 long trommel screens the discharge product at a cut size
grinding is the required process when size reduction of below mm is needed. grinding is a powdering or pulverizing process of many kinds of minerthe rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. rod mills accept feed up to about mm and produce a product in the size range of 3000 to 270 mmthe isamill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
