The Bond abrasion index (Ai) is used as a measure of the relative abrasivity of different rock materials on metal and is important to understand for process plant design and operation in crushing, screening, and especially grinding (Bond, 1963). Iron ores are moderate to strongly abrasive with Ai values typically higher than shale and limestone ...

With the Shatter Index value of Muko iron ore falling between 0.57 wt% and 2.01 wt%, it can be noted that Muko ore can hold its form when subject to impact loading. As an example, the shatter index values of 10 commercial iron ore samples from ten different mines of Orissa in India were between 0.68 wt% to 1.80 wt% . Comparison with these ores shows that Muko ores' Shatter Index value is ...

These models have delivered two main hardness descriptors, the Bond work index and the SAG power index. These parameters and plant operational specifications have been used as input information to forecast, the expected throughput and ball mill product size (P80) for each block of ore. Two forecasting techniques have been used, an in house model, strongly dependant of bond work index and ...

Hardness Hardness determines whether an abrasive particle can etch or provide an anchor pattern on a particular substrate. One way to determine the hardness of an abrasive is to use the Mohs' hardness scale. The scale ranges from 1 to 10, with 1 being the softest (talc) and 10 being the hardest (diamond). Most abrasives that effectively achieve an anchor pattern on a surface have a Mohs ...

The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process. Wet rod mill: Rods: lb/kWh = 0.35(Ai – 0.020) 0.2: Liners: lb/kWh = 0.035(Ai – 0.015) 0.3 : Wet ball mill ...

The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.
