How Ball Mill Ore Feed Size Affects Tonnage & CapacityJul 26, 2017 . The rod mill was needed to reduce feed size to the ball mill because crushing plant output was normally coarser than 80% passing 10,000 microns. Such feed causes power inefficiency if fed directly to a ball mill. Even though the rod mill could be a relatively inefficient device for both energy and metal.ball mills final product size,Ball Mills - 911 MetallurgistDec 23, 2017 . Many grinding circuits necessitate regrinding of concentrates or middling products to extremely fine sizes to liberate the closely associated minerals from each other. In these cases, the feed to the ball mill may be from 10 to 100 mesh or even finer. Where the finished product does not have to be uniform,.

Optimum choice of the make-up ball sizes for . - Science Direct

Abstract. A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters.

Ball mill - Wikipedia

Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition. Size: The smaller the media particles, the smaller the particle size of the final product. At the same time, the grinding.

Ball mills | planetary ball mill | Korea Crusher Plant

Ball mills Type T are to produce a finished product from relatively fine feed in an open or closed circuit. These ball mills are equipped with thinner shell liners and employ smaller size grinding balls than that of Ball mill Type C . Ball mills are widely applied in cement industry, chemical industry, new building materials,.

Grinding Mill Types, Construction, and Usage | Grinding Mills .

The product size from a rod mill is much coarser. Hence a rod mill generally precedes a ball mill in a grinding circuit especially where a fine size product is required. Ball Mills: The final stages of comminution are performed in tumbling mills using steel balls as the grinding medium and so designated "ball mills." Since balls.

Rod mills, how they function

The 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 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35.
