1. Rittinger’s Law: n = 2 . K r is Rittinger’s Constant . 2. Kick’s Law: n = 1 . K k is Kick’s Constant . 3. Bond Crushing Law: n = 1.5 . W i is Work index in KWh/ton and D in mm . Example 4: Calculate the Power required to crush 50 ton/h of coke given the following data: W i = 115.13 KWh/ton Feed particle diameter = 50 mm Product ...
Determine the energy required to crush the material from 25 mm to 3.5 mm. Assuming: a) Ritttingers law b) Kicks law c) Bond law 2) A material is crushed in a blake jaw crusher such that the average size of particle is reduced from 50 mm to 10mm with the consumption of energy 13.0KW/(kg/s).What could be the consumption of energy needed to crush ...
Chapter 3 - Particle Technology (Size Reduction) Kick’s law: the work required for crushing a given mass of material is constant for the same reduction ratio, ... 3.2.2 Bond crushing law and work index.
Handbook of Crushing Glossary of Terms Angle of Nip — The angle formed between the moving surface of a crusher roll or jaw plate and the stationary plate surface at which point the material will be pinched. Angle varies with machine size and material lump size. Bond Work Index (BWI) — …
rently crushing some corundum (Bond Work Index = 28kWh/t at 400 m, compressive strength up to 700MPa). Some tests have been performed on martensitic steel balls or hard hematite iron ore as well. The eccentricity (r) is also fixed by the design of the range of equipment. The speed (ω) can be changed online with the frequency in-
CHE F313: Separation Processes II Kick’s Law • In 1885 Kick proposed another law, based on stress analysis of plastic deformation within the elastic limit • This law states that the work required for crushing a given mass of material is constant for same reduction ratio – that is the ratio of initial particle size to the final particle size – This law is more accurate than Rittinger ...
