Rock Crushing Theory and Formula using Kick and Rittinger& 39;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 ...

Based on Bonds Crushing Law the power required to crush a ...

Based on Bond& 39;s Crushing Law, the power required to crush a certain material will change by % if the diameter of the product is made smaller by 50%. In crushing a certain ore, the feed is such 80% is less than 50.8 mm in size and the product size is such that 80% is less than 6.35 mm.

Chemical Engineering Stop: Bond’s law

Where Kb is a constant that depends on the type of machine and on the material being crushed. To use this equation, a work index Wi is defined as the gross energy requirement in kilowatt-hours per ton of feed needed to reduce a very large feed to such a size that 80% of the product passes a 100-µm screen.

QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE VALUE DETERMINATION

Abstract: The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Determining the Bond work index value is quite compli ed, time-
