THE BOND WORK INDEX OF LIMESTONE AND ANDESITE

2018-4-6  limestone : andesite = 50 : 50, limestone : andesite = 75 : 25. The Bond work index determination according to the standard Bond's test is done on all these samples with compara-tive sieve size of 74, 105 and 150 microns. The Bond Work Index is calculated using the formula (Bond, 1961): (√ √) (1) where: W i Bond work index (kWh/t); P c

CORRELATION BETWEEN BOND WORK INDEX AND

2014-6-27  magnetite, granite, feldspar and quartz were tested for hardness, abrasion, compressive strength and modulus of elasticity,,and the work index is estimated. 2.1 Hardness Test Th e Rockwell test measures hardness by using diamond cone indenter. The indentation is measured after a lighter initial load is applied and after a heavier load is applied.

Mineral Hardness Scale Specialty Kitchens

The hardness of material is measured by determining which material can scratch or be scratched by others, if they can scratch one another then they are the same hardness. For example if a given material is scratched by Corundum but not by Diamond, its hardness on the Mohs scale is 9.5. The Mohs scale is truly a comparative scale.
