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 (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.
Equation () 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. () 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 ...

•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 ...

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.

Jun 03, 2014· It implies that the specific energy required to crush a material, for example from 10 cm down to 5 cm, is the same as the energy required to crush the same material from 5 mm to mm. Rittinger''s law: Rittinger, assumed that the energy required for size reduction is directly proportional to the change in surface area.
Von Rittinger for d < mm = (−) with W as grinding work in kJ/kg, c as grinding coefficient, d A as grain size of the source material and d E as grain size of the ground material. A reliable value for the grain sizes d A and d E is d 80. This value signifies that 80% .

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.) Our difficulty lies in ...
