Abrasive Index Of Coal

A coal called abrasive when his abrasive index 400-600, and referred not abrasive when his abrasive index < = 10. Coke has abrasive index in 2500 while having an abrasive sandstone index 1200. Desired coal buyers must have abrasive index < = 200. If abrasive index its > 200, the price of coal could be cheaper or perhaps is totally rejected.

An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away by friction.While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the ceramics which are used to cut, grind and ...
