where C(x;y, h) is the single particle breakage function for self-breakage of a particle of size y in free fall from height. h, P(y,h) is the probability that a par ticle of size y will shatter when falling a vertical height h and p(h) is the distribution. density for effective drop heights in the mill.
to mimic the grinding mechanisms observed in industrial units. The best examples of this can be observed in the Bond series, where ball mills, rod mills, and crushers are tested using similar laboratory-scale apparatuses. Similarly, the MacPherson and media competency tests were designed to mimic autogenous grinding mechanisms.

According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961).
Such wheels are used in grinding machines. The wheels are generally made from a composite material consisting of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the bond in grinding wheel terminology) to form a solid, circular shape.

Recently, kinetic model has been mostly used to the design of grinding circuits. In this study, the relationship between the Bond's grindability (Ghj.) and breakage parameters (S„ a-r, y and. ß) were examined. The validity of the obtained relationship parameters of S„ a-r, ß and y has been confirmed.

where Wi is the work index. The work index is the comminution parameter which expresses the resistance of the material to crushing and grinding. Numerically the work index is the kWh per short ton required to reduce the material from theoretically infinite feed size to 80 per cent passing 100 microns, equivalent to about 67 per cent passing 200 mesh.
