A New Approach to the Calculation of Work Index and the …

The work index Wi was defined by F. Bond as the specific energy (kWh/ton) required to reduce a particulate material from infinite grain size to 100 microns. The calculation is based on the size-energy relationship e1,2=C.(1/x2n–1/x1n ), which for n = 0.5, x1 = ∞ and x2 =100, by definition gives e∞, 100 = Wi and consequently C=10Wi. In theory, for a given material the value found …

How to Calculate Grinding Mill Operating Efficiency

In " Crushing and Grinding Calculations ", Bond identified correction factors that should be applied to the calculated power (W) determined by using the Bond Equation. The operating efficiency of production circuits can be measured using the following comparison: Efficiency = Wio/Wi x 100. When (Wio/Wi)x100 is less than 100 this indicates ...

Comminution Testing Equipment in Mineral Processing

It is evident that the selection, of an energy base size can be very important in predicting crushing and grinding results. For example, line (A) in Fig. 1 shows that 14.5-4.00, or 10.5 Kwh/ton would be required to grind from 900 to 70 microns, while line (C) would indicate that 12.9-1.02, or 11.88 Kwh/ton would be necessary.

Development of size reduction equations for calculating

where L P and L F are representative size of product particles and feed particles in millimeters, respectively. K R, J mm g −1, is the Rittinger constant; K K, J g −1, is Kick's constant; and K B, J mm 0.5 g −1, is the Bond constant.. The basis of the Rittinger theory is that the energy consumed for grinding is proportional to the surface area created.
