As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, & Williams, 2006).

The ultimate ball mill with flexibility built in. You can’t optimise cement grinding with a one-size-fits-all solution. That’s why our ball mills are designed to adapt to your requirements, with a high degree of flexibility built in. You decide whether to operate the mill in open or closed circuit, with or without a pre-grinder and withThis plant has 2 lines for cement production (5300 t/d). The ball mill has one component, 5.20 m diameter, and 11.20 m length with 240 t/h capacity (made by PSP Company from Přerov, Czechia). The mill’s rotation speeds are mainly constant (14 rpm), and there is approximately a fixed one-year period of changing liners.Ventilation Prediction for an Industrial Cement Raw Ball Mill

Working Principle of a SAG Mill. The rock and grinding media are placed in the mill and rotated, causing the grinding media to tumble and crush the rock into smaller pieces. The mill operates in a closed circuit with screens that size the ore and send it back to the mill for further grinding. The product from the mill is then sent to a cyclone1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.Difference Between Sag Mill vs Ball Mill Mech4study
