Rock Crushing Theory and Formula using Kick & Rittinger's

Mar 11, 2016 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

is called the crushing strength of the material, we have: dE/dL = -K K f c L 1 which, on integration gives: E = K K f c ln(L 1 /L 2) (11.2) Equation (11.2) is a statement of Kick's Law. It implies that the specific energy required to crush a material, for example from 10cm down to

Mar 25, 2015 Bond’s Law: The work required to form particles from very large feed is proportional to the square root of the surface-to-volume ratio. E = K B f c [(1/L 2 ) 1/2 - (1/L 1 ) 1/2 ] Rittinger’s Law — The energy required for reduction in particle size of a solid

How Material Size Directly Affects Size Reduction Energy

•Kicks law is application •based on stress analysis if plastic deformation within the elastic limit. •More accurate than Rittingers law for course crushing. •Applicable for feed size greater than 50mm. •Bonds law n=1.5 •Particles of average feed size 50 x 10(-4) m are crushed to an average

Bond Work Index Formula-Equation

Jul 15, 2013 See this useful summary Table of Bond Work Index by Minerals. For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball mill test.

Bond s law for crushing mills-Henan Mining Machinery Co., Ltd. A crushing law proposed by Rittinger in 1867 states that. CHE F313: Separation Processes II Bond's Law • A somewhat more realistic method of estimating the power required for crushing and grinding was proposed by Bond in 1952 • Bond postulated that – the work required to form particles of size D p from very large feed is

created, Rittinger's Law fits the experimental data better. Bond’s law • The work required to form particles of size Dp from very large feed is proportional to the square root of the surface to volume ratio of the product • P/f = 0.3162 wi 1 1 √Dp √ Df . P – Power in kW . f – feed rate, t/hr

Cost Basis for the ITC and 1603 Applications | SEIA

In a simple example, if equipment costs $100,000, the solar credit would be 30 percent of the cost basis of $100,000, or $30,000. If the taxpayer elects to receive a 1603 grant in lieu of the ITC, the 1603 award is calculated on the ITC tax basis. In many cases, a solar project developer will not have sufficient tax liability to make immediate

CPE: Lesson 15. Empirical laws of Size Reduction

In using either of the models due to Rittinger and Kick the relevant constant must be obtained by experiment using both the same equipment and the same material. 15.3 Bond’s law and Work Index Bond state that the energy required for size reduction is proportional to the square root of the surface- volume ratio of the product. In Bond’s

Nov 01, 2013 The Bond P80 approach has been the most successful of these, covering ball and rod mills , , with more limited application in crushing. The energy required (E) for size reduction is calculated using the so-called “Third Law”, E = K 1 / x 2 − 1 / x 1, where x 1 is feed size and x 2 is product size. The Bond technique provides a simple

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 the experimental data better. 3) Bond has suggested an intermediate course, in which he postulates that n = -3/2 and this leads to: '= ' 5 4 4 .

Kick’s law is more accurate for coarser crushing where most of the energy is used in opening fractures along already existing cracks. It implies that the specific energy required to crush a material, for example from 20 cm down to 10 cm, is the same as the energy required to reduce the same material from 4

The gyrator crusher consists of a truncated conical casing, inside which a crushing head rotates eccentrically. The crushing head is shaped as an inverted cone and the material being crushed is trapped between the outer fixed, and the inner gyrating, cones, and it is again forced into a narrower and narrower space during which time it is crushed.
