• ### Rock Crushing Theory and Formula using Kick & Rittinger's

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

3/1/1972· THEORY In the theory on the mechanics of rock cutting, we may consider the maximum value of the cutting force, or discuss the initiation of the macroscopic failure crack to form a coarse cutting chip. It is well known that the failure of rock material is a brittle one, and that plastic yield phenomena do not appear in rock cutting.

• ### Fred Chester Bond Wikipedia

Whereas Rittinger's theory held that the work done in breaking rock is proportional to the new surface area produced (that is, inversely proportional to the diameter of the product particles), and Kick's theory held that the work done is directly proportional to the reduction ratio (ratio of feed particle diameter to product particle diameter), Bond's theory held that the work varies inversely as the square root of
