· See this useful summary Table of Bond Work Index by Minerals. 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.
Calculate the compressive strength using the formula S = P/A, where S is the compressive strength, P is the maximum load applied to the specimen and A is the area. Your final compressive strength value will be in units of lbf/in^2, which is the same as pressure or psi.

Please use this calculator to select which product you would like to calculate the total tonnage estimated for your project. You will need the length, width and depth of your project space to be able to get your estimated tonnage calculation.
Each natural stone has a strength rating often referred to as its Mohs hardness. The Mohs scale of mineral hardness was developed to identify the strength and hardness of any natural mineral. For instance, if a stone has a Mohs hardness of seven, then that stone is solid enough to scratch another stone with a rating of six or lower.
Limestone sales comprised the second largest portion of this market at 35% by tonnage. Dominating the sales were curbing, paving, rough blocks, slabs, veneer, wall panels, and tile.
