Nov 01 2002 Equations for power draft capacity and work input for predicting the performance of industrial grinding mills are derived based on torque measurements using a laboratory instrumented mill. These derivations are based on mechanical principles and on the first-order kinetics of the grinding process. Rittingers Kicks and Bonds laws express work input as work index Wi times a particle.
Typically R 8. Rod Mill Charge Typically 45 of internal volume; 35 – 65 range. Bed porosity typically 40. Height of bed measured in the same way as ball mills. Bulk density of rods 6.25 tonsm3. In wet grinding the solids concentration 1s typically 60 – 75 by mass. A rod in situ and a cutaway of a rod mill interior.

Nov 18 2008 Summary The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium e.g. steel balls put in the shell and has a simple structure and ease of handling. Furthermore The Ball Mill of a large capacity has been available to a very extensive range of applications in both dry and wet.
Installing a 1000kW regrind ball mill increased plant capacity by 56 through treating 29 of the cyclone underflow and reduced the SAG mill specific energy from 20.

equation for ball mill circuits. • Define and calculate the classification system efficiency of a ball mill circuit. • Define and calculate the grinding efficiency of the ball mill in a ball mill circuit. • Relate overall ball mill circuit output and circuit efficiency to specific design and operating variables.
The capacity not only determines the mill equipment size but also dictates how to operate the mill whether continuous or batch operation is required and whether the process can be performed in-house or if a tolling service is a better option.
