Bond Abrasion Index Test Machine 911Metallurgist

Bond’s Abrasion Test AKA Allis Chalmers Abrasion Test. Bond’s abrasion test consists of a hardened Cr-Ni-Mo alloy steel paddle (hardness 500 Brinell). 7.62 cm X 2.54 cm X 0.64 cm with 2.54 cm of its length silling inside a rotor. 11.43 cm diameter. The rotor is covered by a concentric steel drum 11.43 cm in length and 30.54 cm in diameter.

A Mill Abrasion Test for Wear Resistance of Armour Stone

The abrasion mill test uses increments of milling time to generate a weight loss curve, the slope of which gives the abrasion resistance index. This new index, k s is compared with wet attrition and aggregate abrasion values for a suite of 11 rocks with wide ranging strengths.

Bond Work Index an overview ScienceDirect Topics

Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).

CORRELATION BETWEEN BOND WORK INDEX AND MECHANICAL

The value of Bond work index of the above samples has shown a variation from 10.8 kwh ton-1 for bauxite (high abrasion value and low compressive strength) to 20.4 kwh ton- 1 for granite (low abrasion value and high modulus of elasticity).
