Difference Between Sag Mill vs Ball Mill - mech4study

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially. Interior of ...

Bond Work Index Formula-Equation

Basic EquationsSize Distribution and Exposure RatioEquations For Work Index VariationsWork Index and Crack EnergyThe basic work index equation is:W = 10 Wi/√P – 10 Wi/√F(1)where W is the work input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% passing P microns, and Wi is the work index, or the grinding resistance parameter. It represents the energy input required in kilowatt hours to reduce a short ton from theoret在911metallurgist上查看更多信息

Bond Work Index - an overview ScienceDirect Topics

Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).

Calculate and Select Ball Mill Ball Size for Optimum

2020-5-15  In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and ...

Factors of Safety - Engineering ToolBox

2020-5-15  Factors of Safety - FOS - are a part of engineering design and can for structural engineering typically be expressed as FOS = F fail / F allow (1). where . FOS = Factor of Safety. F fail = failure load (N, lb f) . F allow = allowable load (N, lb f) . Example - Structural Steel Column in a Building. Due to buckling the failure load of a steel column in a building is estimated to 10000 N.
