The test results in a value for HGI were generally between 30 and 100. A high value indicates that a crusher using this material will have a high output while a low value indicates the crusher will have a reduced capacity using this material. Galena was assumed to have an HGI value of 100 and lower value of HGI means harder material. 4. Results

In large coal preparation plants with a capacity of 30 million tons/year, the belt speed can reach 7 m/s and the thickness of the material layer can reach 500 mm. Therefore, in highthroughput and complex environments, the problem exists that harmful feeding materials such as iron and gangue are not easily detected, and thus fault diagnosis in the crushers lags behind.
