Rock Crushing Theory and Formula using Kick Rittinger's Law

Mar 11, 2016  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 ...

Fred Chester Bond - Wikipedia

Bond Work Index. In the 1930s through early 1950s, Bond developed a new theory of comminution that introduced an index, called the 'Bond Work Index', which relates power consumption in crushing and grinding to the feed and product size distribution. His theory and index were introduced in a widely cited 1952 journal article. Bond called his theory the "third theory of comminution", counting ...

How Material Size Directly Affects Size Reduction Energy ...

Mar 25, 2015  Rittinger’s Law — The energy required for reduction in particle size of a solid is directly proportional to the increase in surface area. E = K R f c (1/L 2 – 1/L 1 ) Kick’s Law — The amount of energy required to crush a given quantity of material to a specified fraction of its original size is the same, regardless of the original size.

CPE: Lesson 15. Empirical laws of Size Reduction

Kick’s law has been found to hold more accurately for coarser crushing, where most of the energy is used in causing fracture along existing cracks. In Kick’s law the energy input is proportional to the size reduction ratio. In other words the same energy input is required for a reduction in size from 1 cm to 1 mm as for a reduction from 100 ...
