Customer ServiceRittingers law has been found to hold better for fine grinding, where a large increase in surface results. It suggests that the energy required is proportional to the increase in surface area per unit mass. 15.2 Kicks law
According to rhodes 2008, the typical application range of rittingers law is to ultrafine grinding below 30 micron. breakage rate exponents for particle volume extracted from 15 literature data sets indicate values in the range 14-1. these bracket the value of 13 implied by rittingers law and do not support the values implied by the ...
Dec 12, 2017nbsp018332in this study, the grinding kinetics and the flowability of balloon flowers bfs with various moisture contents 8, 12, and 20 were determined. three semi-empirical grinding models bond, kick, and rittinger were applied to describe the bfs grinding process.
Law of kick. the slope of cumulative curve varies from m 0 to m 0.1. the range of coarse grinding is the range of bonds theory, rn 0.5 and the range of fine grinding is the range of rittingers theory m 1.0 . - the range of fine grinding from m 1 to 3, the range of approaching grinding
Grinding laws namely kicks, rittingers and bonds law were applied. the grinding constants k-k, k-r, w-i for different laws reflected the dependency on grinding duration. dry grinding of raw ...
Development of three well-known grinding equations rittinger, kick, and bond in some publications these three equations are referred to as grinding laws. these equations

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, kicks 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, rittingers law fits the experimental ...
Grinding and cutting reduce the size of solid materials by mechanical action, dividing them into smaller particles. perhaps the most extensive application of grinding in the food industry ... equation 11.3 is known as rittingers law. as the specific surface of a particle the surface area per unit mass is proportional to 1l, eqn. 11.3 ...

May 14 2010 183 rittinger s and kick s laws rittinger s law states that work required in crushing is proportional to the new surface created. in other words crushing efficiency is constant and for a given machine and feed material is independent of the sizes of feed and product. rittinger s law is written as-chat online grinding materials ...
Rittingers 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 1l 2 1l 1 kicks law the amount of energy required to crush a given quantity of material to a specified fraction of
And over 150 batch grinding tests and sieve sizing were carried out. throughout the grinding tests, power draw was continuously monitored. the relationship between the grinding energy and product size was analysed using the conventional energy-size concepts. it was found that the rittinger equation fits the experi-mental data well.
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
Oct 10, 2014nbsp018332 rittingers 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. kicks law, more closely relates to the energy required to effect elastic deformation before fracture occurs, and is more ...

In simple terms, rittingers law is a high-end estimate of the energy required to grind something, excluding any losses to heat etc. kicks law is a low-end estimate, and bonds law is a mid-way ...
The final theory of particle reduction is bonds law that states the total work input by the weight of crushed material is inversely proportional to the square root of the diameter of the product particles figure 7. bonds law functions best in between the coarse grinding of bonds law and the fine grinding of rittingers law. e ...
