The mill receives crushed ore and process water at a variable flow rate to achieve the correct pulp density. Lime, zinc sulphate and sodium metabisulphite (SMBS) are also dosed to the ball mill to condition the ore prior to the flotation circuit. The ball mill discharge passes over a slotted trommel screen with an aperture size of 10 mm x 25 mm.
A basic design is a fabricated metal structure with a protective coating of abrasion resistant rubber. The pulp lifters have three main functions. First they must provide adequate support for the grate wall, secondly they must efficiently discharge the product from the mill and finally they must protect the mill structure from wear.
The type of mill also is a factor as if it is an overflow mill (subject to the diameter of the discharge port) is usually up to about 4045% If it is a grate discharge you will have more flexibility of the total charge Ball size and ball grade is determined by the feed ore size and hardness, plus the PH level of the slurry
