Rittinger and Kick's Laws of Crushing

I happen to be one of those who believe that Rittinger probably meant what he said when he wrote what Stadler has quoted, “the increase of the surfaces exposed is directly proportional to the force required for reducing” “and therefore also to the work absorbed in effecting the separa­tions.” (The italics are now mine instead of Rittinger’s or Stadler’s.)

Rittinger an overview ScienceDirect Topics. Neither of these two laws permits an accurate calculation of the energy requirements. Rittinger's law is applicable mainly to that part of the process where new surface is being created and holds most accurately for fine grinding where the increase in surface per unit mass of material is large.

A commentary on the Kick, Bond and Rittinger laws of grinding

Confusion concerning the so-called general law of grinding proposed by Walker et al. is removed when it is realised that two forms of the law exist, quite different in physical meaning. The Kick and Rittinger laws are special cases of one form, and Bonds law is a special case of the other.

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

Rittinger an overview | ScienceDirect Topics

Kick’s law, valid for particles greater than 0.5 cm, was used less than Rittinger’s law, which proved to be interesting for particles smaller than 100 μm at the mouth of the grinder. Bond [BON 52] made the hypothesis that the exponent of d p is the arithmetic mean between Rittinger and Kick’s values, being 0.5.

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.

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

How it Works: Crushers, Grinding Mills and Pulverizers

Crushers, grinding mills and pulverizers are types of grinding equipment used to transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Several theories for the science of size reduction have been developed, including Rittinger’s Law, Kick’s Law, and Bond’s Law.

Unit Operations in Food Processing R. L. Earle

It has been found, experimentally, that for the grinding of coarse particles in which the increase in surface area per unit mass is relatively small, Kick's Law is a reasonable approximation. For the size reduction of fine powders, on the other hand, in which large areas of new surface are being created, Rittinger's Law fits the experimental

Comminution Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with

In Summary, Kick's law is better for larger particles and Rittinger's for fine grinding, see Figure11.5. Large particles are easier to break than smaller ones as they have more cracks and faults. Often the laws are used in conjunction with empirically given constants: it can be dangerous to use the book values without some test work.
