## Bond Work Index an overview | ScienceDirect Topics

The Bond work index (Bond, 1960) is based on Bond’s law, which states that the energy consumed is proportional to the 15 power of particle size rather than the square of Rittinger’s law Accordingly, the energy consumed in reducing the particle size from x F tobond crushing work index The test determines the Bond Impact Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing crushers It is also used to determine the required openside settings jaw crushers and gyratory crushers or closedside settings cone crushers for a given product sizebond crushing work index jugendfeuerwehrriepsdorfde19062015· Avg Bond Work Index: kWh/t: kWh/t: kWh/sht: kWh/t: kWh/t: kWh/t: kWh/t: Range: No of Tests: Alumina: 179: 734: 6: Andesite: 201: 183: 201: 195: Barite: 63: 47: 52: 50: 58: 49: 7: Basalt: 189: 171: 188: 190: 190: Bauxite: 97: 95: 88: 97: 100: 100: 145: 131: 29: Cement clinker: 150: 131: 135: 148: 150: 150: 136: 777: 180: Cement (raw) 116: 120: 106: 100: 327: 284:Table of Bond Work Index by Minerals 911 Metallurgist

## Effect of core diameter on the Bond impact crushing work

The Bond low energy impact (crushing) work index test is specified to be performed on rock specimens between 50 mm and 75 mm in effective diameter NQdiameter drill core, frequently used in mineral exploration programs does not meet that specification, it being 45 mm diameter or less This paper reports the effect of performing the impact test on contiguous sections of HQ diameter and NQBased on a large number of tests, Bond introduced a working index or comminution parameter that represents the resistance of the material to crushing and grinding(PDF) Impact work index prediction from continuumbond crushing work index equipment for sale Construction Waste Crushing Line 1 price of jc 250 x 1000 mobile crushing plant coal crusher machine benefits pcx impact crusher fine indian manufacture stone crusher dealer at guwahati standard bond work index power consumption of vertical roller mill for line grinding laboratory scale crusher used for sale sinolinking alluvial gold beneficiationbond crushing work index surabhicollege in
