Rock Crushing Theory and Formula using Kick & Rittinger's Law

Metallurgical ContentThe Two Laws:What about Bond?Rittinger’s Law:The Crushing-Surface Diagram: 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

Rock breakage by crushing, blasting, and drilling

The fundamental principles of rock fragmentation by crushing, blasting, and drilling are not well understood; however, empirical observations have provided means for predicting the energy requirements for these processes. Experimental procedures and methods of analysis used in comminution studies are described in this review.

How it Works: Crushers, Grinding Mills and Pulverizers

For more on Kick and Rittinger’s Law, see “Rock Crushing Theory and Formula using Kick & Rittinger’s Law” on 911 Metallurgist. Crushers. Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. During the primary crushing operation, boulder size feeds from

Chipping and crushing mechanisms in orthogonal rock

In the proposed approach, a rock crushing zone is introduced at the rock-cutter interface beneath the cutter's rake face, namely the Tip Crushing Zone (TCZ), which, as a destruction kernel, is responsible for both the crushing and chipping phenomena occurring in the cutting process.
