  • Study of degradation characteristics of Bowen Basin coal

    Abstract. The degradation characteristics of South Blackwater and Ensham coal from Bowen Basin area in Central Queensland area has been studied by ball mill test with "partially-cushioned coal" and "Cushioned coal" to measure the fines generation during handling through the Gladstone Port Authority s ship loading facility. This paper presents the results of a study of the production of porous biodegradable composite materials by co-grinding followed by scaffolding. Dry powders of polylactic acid and nanocrystalline carbonated apatite analogous to bone mineral were co-ground in a tumbling ball mill in order to disperse the mineral filler within the polymer.

    The mineralogy and liberation characteristics of the comminuted Penouta leucogranite host of the Sn-Ta ore were determined. Grinding developed by a combination of high-pressure grinding rolls (HPGR) followed by a ball mill (BM) was compared with a single ball mill process. The mineral characteristics of the grinding products were analyzed using a Tescan Integrated Mineralogical Analyzer (TIMA The 750-g charges of minus 10-mesh porphyry copper ore were ground for 6 min at 60 pct solids in a laboratory ball mill to produce all minus 65-mesh material.
