Rock Crushing Theory and Formula using Kick Rittinger's Law

Rittinger’s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: “The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of rock is proportional to the reciprocal of the ...

The grinding is usually done with hard ore pieces or hard steel balls, sometimes both. The product of crushing and grinding is a water–particle pulp, comprising ∼35% solids. Flotation is done immediately after grinding—in fact, some flotation reagents are added to the grinding mills to ensure good mixing and a lengthy conditioning period.
