An industrial ball mill is a type of ball mill used in large-scale production settings. It is designed to process large volumes of material and can be used for both wet and dry grinding. Industrial ball mills are typically made of steel, and the lining material is selected based on the type of material being processed. 4 Conical Ball Mill
Ball mills typically use water or other liquid and additives to help reduce friction and provide cooling during the grinding process. The feed enters one end of the ball mill, and discharges out the other end. …

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.
EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.
• Transfer size (T80) is the term used to describe the SAG mill product that is sent to the ball mill. For peak performance and balancing the power available in the SAG mill and ball mill, the transfer size must be measured and controlled. • The transfer size will be 500 microns using a 12mm opening trommel. This can be true under special
