Determining the Bond Efficiency of Industrial Grinding
It is an essential tool for managing the important business (cost) of grinding. The guideline first presents the method for Bond Efficiency determination, which applies to most brittle materials in their naturally occurring (unscalped) size distributions being treated in size reduction circuits down to an 80% passing size of the circuit product (P80) of approximately 70 m.

Grinding Media Ball Examination LMATS
Mill Grinding media ball quality is central to efficient and costeffective comminution of a mill operation. Comminution costs are mainly electricity, grinding balls and liners. Of these three components, grinding balls form the major portion of the consumable costs, and can be as high as 40%–45% of the total.

A New Approach to the Calculation of Work Index and
The work index W i 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 sizeenergy relationship e 1,2 =C.(1/x 2 n –1/x 1 n), which for n = 0.5, x 1 = ∞ and x 2 =100, by definition gives e∞, 100 = W i and consequently C=10W i.
