Technique to Investigate Pulverizing and Abrasive Performance of Coals in Mineral Processing Systems

The operating costs of breaking coal particles into fine powder, to achieve optimum combustion for the boilers in a power plant, are made up input carry on an energy intensive comminution mechanism and overcome friction losses within pulverising machines. also include cost replacement processing system’s components due wear. This study presents development application attrition test machine that enables investigation factors influence pulverizing efficiency. tester simulates grinding conditions real vertical spindle mills. In this kind mill, as with tester, size reduction process results from shearing action during redistribution particles. bed forced by movement rollers (or disc rotation, case tester). testing method was oriented toward mechanical properties, i.e., internal shear strength, abrasiveness grindability. facilitated procedures more exact simulation Ball-race mills Loesche roller were used.
