Abstract A comparison of the amount of minus-28-mesh product produced by a standard grinding test procedure is provided for 45 non-metallic materials. The percentage of product, the weight of product per unit of energy used and the weight of product per mill revolution are shown.
The results exhibited excellent reproducibility and demonstrated an accurate comparison of grindability for non-metallic materials.
Keywords: Grinding, Non-metallics, Industrial minerals, Mineral processing.
