The ball mills would have to be 2.9 m x 4.3 m with 450 kW installed to grind a typical 14 mesh rod mill product to final size. Therefore, alternative grinding circuits were evaluated. For 900 t/d these were: Base Case Rod mill and two ball mills. (Insufficient power and wrong split; mills too large to fit Hercules transport.) Alternative A
For this study, materials (copper sulphide ore) were sampled from the SAG mill feed in Sungun copper concentrator plant. The density of ore was 2.8 g/cm 3.The ore was crushed in a laboratory scale jaw crusher and roll crusher successively to prepare materials for ball mill grinding tests.
Autogenous, semi-autogenous, and conventional rod mill-ball mill grinding were considered: Conventional crushing and grinding plants are safe and conservative. The ore can be tested by proven techniques and crushers and mills selected with assurance that they will meet performance requirements. Operation of crushing plants, rod mills and ball
Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material. In tower mills, there is no cascading action as in standard grinding mills. Stirred mills are also common for mixing quicklime (CaO) into a lime slurry. There are several advantages to the tower mill: low
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do.
