Prediction of mill grindability using percussion drilling data.
For Reference Only At Bureau Libraries, 1987; :1-42
This report presents the results of a preliminary examination of the relationship between grindability and percussive drillability in hard and soft rock. The research indicates that grindability increases along with drillability but in a nonlinear fashion owing to relative differences in the ratio between these two factors in soft and hard rock. It was also determined that the specific energy index for grindability is highly dependent upon the average particle size and size distribution of the materials.
