 · 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.

The constants (Kb, Kr and Kk) used in the laws of crushing (, Bond's law, Rittinger's law and Kick's law) depend upon the a) Feed material b) Type of crushing machine c) Both A .

Bond Crushing Law A Calls For Relatively Less Energy For. 6 Bond crushing law a. Calls for relatively less energy for the smaller product particles, than does the Rittinger law. b. is less realistic in estimating the power requirements of c. states that the work required to form particle of any size from very large feed is proportional to the square root of the volume to surface ratio of the ...

 · Content Crushing laws Rittinger law Kicks law Bonds law Slide 3 Introduction In the materials processing industry, size reduction or comminution is usually carried out in order to: Increase the surface area because, in most reactions involving solid particles, the rate of reactions is directly proportional to the area of contact with a second phase.

Based on Bonds Crushing Law the power required to crush a • Based on Bond's Crushing Law, the power required to crush a certain material will change by % if the diameter of the product is made smaller by 50%. • In crushing a certain ore, the feed is such 80% is less than mm in size and the product size is such that 80% is less than mm. Chemical Engineering Stop: Bond's law. May ...

 · 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 ...

 · Bond's law. Bond postulated that work required to form particles of size Dp from very large feed is proportional to the square root of the surfacetovolume ratio of the product, Sp/Vp. By relation Sp/Vp = 6/ɸsDp, from which it follows that. Where Kb is a constant that depends on the type of machine and on the material being crushed.
