Experimental research on relative grindability of material

The effect of two different methods on the detection results of relative grindability of material was studied. The re- suits showed that the laser particle size analysis was more convenient and effective than screen analysis. The laser particle size analysis could reduce influence of particle agglomeration on the detection results of relative grindability of materials, and the new relative grindability coefficient formula was defined based on this. The results indicated that the relative grindability coefficient of different materials had larger difference. The relative grindability coefficient of some materials was increased with grinding time extension, and relative grindability coefficient of some other materials changed little or reduced with grind- ing time extension.
