The applicability of the introduced operating Rittinger index and the lower limit size of Rittinger law are studied. Furthermore, the effect of solid concentration of suspension, ball filling ratio, circumferential speed of the stirrer, and size of grinding media on the fineness (median particle size and specific surface area) was examined.

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, …

Thus, the higher the index, the easier is the grinding task. This method loosely assumes that the specific energy consumed is proportional to the new surface generated, following the concept of Rittinger 's law of comminution. Berkowitz (1994 p.96) gives a generalized variation of the Hardgrove index with coal rank. According to the variation ...

Oct 25, 2016· However,equations Rittinger's law and Bond's law were developed from studies of hard materials (coal and limestone) and deviation from predicted results is likely with many foods. 15. Basic parts of mill • Feed chute/hopper, which delivers the material. • Grinding mechanism usually consisting of a rotor and stator.

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.

Where x 1 is the average initial size of the feed particles, x 2 is the average sizeof the product particles, E is the energy per unit mass required to produce this increase in surface area and K is a constant, known as Rittinger's constant. Rittinger's law has been found to hold better for fine grinding.

Oct 01, 2020· Several comminution laws have been proposed to link the consumed energy to a characteristic particle size of the powder. The popular models are those of Rittinger, Bond and Kick . While the Bond and Kick models are mostly employed for coarse and intermediate size grinding, the Rittinger model is better suited for fine comminution .

Rittinger's Law states that the energy required in size reduction is proportional to the new surface created by the particle fragmentation. The equation for Rittinger's Law can be written as: E = K R f c (1/L 2 – 1/L 1) Where: E=Energy, K R =Rittinger's Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 ...

Determination of energy required in size reduction is generally done using either Kick's law or Rittinger's law. Kicks's law is used for coarse grinding when the size ratio of original material to end materials is 8:1. Bond's law and Retinger's law are used for intermediate and fine grinding …

grinding in which there is a relatively small increase in surface area per unit mass. Rittinger's law gives better results with fine grinding where there is a much larger increase in surface area and Bond's law is intermediate between these two. However, equations (4.2) and (4.3) were developed from studies of hard materials (coal and ...

• Grinding of coarse particles in which the increase in surface area per unit mass is relatively small, Kick's Law is a reasonable approximation • Rittinger's law – States that the energy required for size reduction is proportional to the change in surface area of the pieces of food • …

Parboiled rice required longer duration of grinding compared to raw rice, consequently specific energy consumption was higher (~220kJ/kg). All the three classical laws of grinding (Kick's, Rittinger's and Bond's) seemed to be applicable while Rittinger's law showed better suitability than the other two followed by Bond's law.

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. ... The Bond Work Index is material specific and is obtained from laboratory crushing tests on the feed material.

Bond (1952) proposed the 'Third Law' of grinding. The Third Law states that the net energy required in comminution is propor- ... stating that each of Rittinger, Kick and Bond theories might be applicable for different narrow size ranges. ... between the product P80 and the net specific grinding energy for all LIMS tail (non magnetic) and ...
