Rock Crushing Theory and Formula using Kick & Rittinger…
In Fig. 17 the results obtained in A and B on the siliceous Mexican ore have been plotted in a mechanical-value diagram. For the coarser crushing A, 0.041 E. U. per foot-pound-applied on 100 g. was the result, while in the case of B only 0.018 E. U. (etc) resulted, 125 per cent, more being produced when the coarser crushing was done.

Mineral dressing (= Orebeneficiation)
– i. Primary Crushing (coarse crushing): In primary crushing, ore or run-of-mine ore (up to 1 m in size) is crushed down to about 10 cm and it is done in a jaw or gyratory crusher. – ii. Secondary Crushing (intermediate crushing): In this case, ore is crushed from 10 cm to less than 1 –2 cm size; for this
