how o select ball mills type in iron ore projects

Step 1: Mill overload power •Determine a set of operating conditions that reflects the maximum “overloaded” condition that the mill should be able to handle: –SAG mills: 20% v/v ball charge, 30% v/v filling and 78% critical speed with worn liners –Ball mills: 36% v/v filling and 78% critical speed with worn liners

    Optimization of Solids Concentration in Iron Ore Ball

    Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore

    The ball mills are operated in closed circuit with hydrocyclones to obtain the target P80 grind size of 300 m. Each Ball Mill discharges into its dedicated pump box equipped with pumps, each feeding one 1.2 m diameter, 12-place, hydrocyclone cluster. The hydrocyclone U/F is recirculated back to the ball mill while the O/F is fed to the primary magnetic separation circuit. This configuration applies to Phase 1 of the Project
