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.
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 2.5 mm. Rittinger's law: Rittinger, assumed that the energy required for size reduction is directly proportional to the change in surface area.
Rittinger Law Specific Grinding - 5signori. A theory must never be shown to be wrong; if it is, the theory is disproven. This is one of the best known building stones in the United States. Kazir. In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review. H, shown ...
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 ...
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.
Von Rittinger for d < 0.05 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% .
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

15.1 Rittinger's law ... Rittinger's 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. ...

where E is the net specific energy; x f and x p are the feed and product size indices, respectively, and K 2 is a constant. Bond (1952) proposed the 'Third Law' of grinding. The Third Law states that the net energy required in comminution is proportional to the total length of .

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 ...

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.
