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.
Metallurgical ContentThe Two Laws:What about Bond?Rittinger’s Law:The Crushing-Surface Diagram:Kick’s Law:Method of Tests:Record of Tests:Summary of Results:Appendix: 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 ...Bond F.C., 1961.

And Kick’s law would apply to these, but the effect of the energy absorbed by these few crystals would have no appreciable effect upon the total of energy absorbed when actual crushing takes place. I consider that the above reasoning applies to bodies in tension, shearing, or compression; it can be shown, I believe, that these three phenomena ...CHAPTER 11 SIZE REDUCTION - NZIFST - Homeis 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& 39;s Law. It implies that the specific energy required to crush a material, for example from 10cm down to 5cm, is the same as the energy required toCPE: Lesson 15. Empirical laws of Size ReductionThe Bond Work Index is material specific and is obtained from laboratory crushing tests on the feed material. Hard and brittle materials have a work index in the range 4 × 10 4 − 8 × 10 4 J/kg. Bond’s law holds reasonably well for a variety of materials undergoing coarse, medium and fine size reduction. Eq. 14.3a can also be reduced to
See Page 1. Based on Bond& 39;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 50.8 mm in size and the product size is such that 80% is less than 6.35 mm. The power required is 89.5 kW.Top Savings bonds Up to 3% - 1,2,3 and 5 Year Terms AvailableSavings bonds Up To 4%.Search For 1, 2, 3 and 5 Yr Bonds Savings bonds 4%.Search For 1,. 2, 3 and 5 Yr Bonds Best Investment Bonds - Search Fast and SecureBest Investment Bonds - You Won& 39;t Believe The Top 10 Results
