Size reduction theories - slideshare

Jan 24, 2014 · Applications: Applicable to brittle materials undergoing fine milling. This theory ignore deformation before fracture. 7. 8. Bond's work index is the work required to reduce unit weight from a theoretical infinite size to 80% passing 100µm. This theory is useful for rough mill sizing.

Size Reduction | Mill (Grinding) | Chemistry

SIZE REDUCTION. Rittinger's law is more applicable to fine grinding operations where the increase in surface per unit material is large .Proposed by Rittinger in 1867 .States that the work required in crushing is proportional to the new surface created .Rittinger's Law .

SIZE REDUCTION AND SIZE SEPERATION |authorSTREAM

Upon integration, we get E = K ln (1 / L final – 1 / L initial ) Using K = K R f c where K R is Rittinger's constant f c is the crushing strength of the material Therefore, E = K R f c ln (1 / L final – 1 / L initial ) ( Rittinger's Law) Application: 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 the experimental data better.

Rittinger and Kick's Laws of Crushing

Rittinger and Kick's Laws of Crushing. Using the notation of the original paper, the number of these planes of fracture is represented by the expression 3 (U/S – 1). The area of each plane of fracture is U². The total area of fracture is then equal to 3U² (U/S – 1) which may be written 3U² (U-S)/S.

Rock Crushing Theory and Formula using Kick & Rittinger's Law

Rittinger's Law: Rittinger's theory is the law of the cracks. It is well explained in an article by E. A. Hersam in the Mining and Scientific Press, an abstract of which is given in the third volume of Richard's Ore Dressing, and to which I acknowledge my indebtedness for some of my ideas and,methods.

Application of Kick's and Rittinger's theories has been met with varied success and are not realistic for designing size reduction circuits (Charles, 1957). However Bond's Third Law can be reasonably applied to the range in which ball/rod mills operate in. In spite of the empirical basis of Bond's

• 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 ...
