Following grinding in the ball mill, the material is returned via the sump (8) to the secondary hydrocyclone (9) for resizing. The trash screen (10) removes wood from the old mine workings that may have found its way into the processing circuit.

The VRM, depending on the roller size, has a high reduction ratio; feed from 80 mm to 140 mm to a product of P80 at 75 µm in one pass, the mill is a closed circuit on its own having the comminution and classification of product in a single machine. Sulphide copper-gold ores are usually sorted by flotation.

Autogenous mills are common in the primary processing unit for the major large grinding circuits in the mining field, separates out some precious metals, like gold, silver.

Over-grinding does not have a significant benefit to gold recovery but reduces the mill throughput and results in higher unit costs in terms of energy, grinding media and reagent consumption. If there are frequent changes in ore hardness, grinding circuit performance is affected and poses challenges for operators to maintain the target particle size.

Kinross Gold significantly expanded production capacity at Tasiast gold mine in Mauritania, adding incremental crushing and grinding capacity to the existing carbon-in-leach (CIL) circuit. The company selected ABB's 26 MW gearless mill drive system (GMD) for the mine’s 40 ft SAG mill, as well as other drives, electrical infrastructure equipment and a long-term service

Gold Mine, Kazakhstan . Stephen Flatman ¹, Michael Battersby 1, however, ha seen the development of a number of grinding mills specifically designeve d for ultra-fine grinding in the minerals industry. This has lead to a commensurate reduction in cost unless cognisance of this is taken in the final process design.

The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself. In order to ensure that the rock is ground finely enough the SAG mill has a trommel screen (5), which acts like a large sieve.

Grinding Mills: Ball Mill & Rod Mill Design & Parts Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads.

The design of such grinding mills is extremely critical, requiring sophisticated software tools, proprietary calculation worksheets, and experienced technical engineers and drafters. This blog will review how the mill design process has changed over the last 30 years.

Rod mills are very similar to ball mills, except they use long rods for grinding media. 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.
