Abstract: |
Upon a brief description of the Bond grindability test method and the principle of Bond work index determination, the main factors affecting the determination result for fine grinding as well as the possible measures which may be taken to increase the accuracy of the result are discussed, the Levin’s method to determine specific energy consumption for fine grinding by doing batch grinding tests with the Bond test mill is introduced, and the proper way of considering the influence of grinding fineness on the specific grinding energy by sizing of fine-grinding mill pointed out. |
