•A crushing law proposed by Rittinger in 1867 states that – the work required in crushing is proportional to the new surface created • This law, which is really no more than a hypothesis – is equivalent to the statement that the crushing efficiency is constant and, for a given machine and feed material – is independent of the sizes of feed and ...

Bond called his theory the "third theory of comminution" counting those of Peter von Rittinger and Friedrich Kick as the first and second. This term and the terminology of "laws of comminution" as in "Rittinger's law" "Kick's law" and "Bond's law" are sometimes used in the field, along with those of subsequent researchers .

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. ... Calculate the specific grinding energy for the fine particle tumbling mill to give a product P 80 of 106 μm. Solution.

the grinding laws. THE GRINDING LAWS The amount of energy required for size reduction of solid foods can be theoretically calculated based on the following equation: d d, n x E K x = − (1) where: dE is the energy required in breaking a unit mass of diameter x about size dx, K and n are constants depending on the ground material and grinding ...

Neither of these two laws permits an accurate calculation of the energy requirements. Rittinger's law is . Airborne Dust Liberation During Coal Crushing CDC. Analogous to the laws of Bond, Kick and Rittinger [20], more specific energy is required to crush coal material into smaller product sizes.

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.

Oct 25, 2016· size reduction,laws involved in size reduction,application & mills 1. SIZE REDUCTION Size reduction is the process of reducing the particle size of a substance to a finer state of subdivision to smaller pieces to coarse particles or to powder. Size reduction process is also referred to as comminution and grinding.

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

Rittinger (1867), Kick (1885) and Bond (1952) all proposed empirical laws to estimate the specific energy requirement for accomplishing a given extent of size reduction expressed in terms of the initial and final particle size (length dimension) and an empirical constant.

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.)

Sep 04, 2016· Three laws of comminution or size reduction such as Kick's law, Rittinger's law and Bond's law are defined and its objectives in … Get Price; rittinger law specific grinding . laws of crushing and grinding The law specifically grinding Rittinger. It is against the law!

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

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 ...

Equation (11.3) is known as Rittinger's Law. As the specific surface of a particle, the surface area per unit mass, is proportional to 1/L, eqn. (11.3) postulates that the energy required to reduce L for a mass of particles from 10 cm to 5 cm would be the same as that required to reduce, for example, the same mass of 5 mm particles down to 4.7 ...
