using the concept of a 'standard' SAG mill with pebble crusher circuit. The JK Bond Ball Mill (JKBBM) test, is a locked cycle grindability test conducted using a standard laboratory Bond Ball Mill with the same steel ball charge and material feed size ( passing mm) as the Bond Ball Mill .
The overpressurization of a laboratory ball mill reactor designed for operation under slightly elevated pressures resulted in a serious injury. The apparatus had been routinely operated under argon and hydrogen pressures of 510 atmospheres for nearly two years. The apparatus had not been tested for operation at pressures greater than 10 atm.
Using the JKMRC's AG/SAG mill model, the results from these surveys together with those from a large data base of pilot scale mills were analysed in terms of their breakage rate distributions.

Rotor Mills. Rotor Mills were designed for multipurpose use. It is commonly used to be an allpurpose mill for the rapid crushing of mediumhard substances into soft substances using a special combination of impact and shearing forces. Because of the product design it can also be used for the dispersion and homogenizing of dry samples.
Mills and Grinders. In a laboratory, most materials required for sampling are, in practice, nonhomogeneous mixtures. The best method of obtaining a small representative sample of the nonuniform whole is to take a quantity of the material large enough to be compositionally representative and reduce it to a fine homogeneous powder.
