Ultrafine grinding of inorganic powders by stirred ball
A series of wet grinding experiments have been carried out using a stirred ball mill to systematically investigate the effect of processing conditions on the final particle size distribution and grinding kinetics A submicron particle size down to 350 nm was achieved, while the grinding energy efficiency or enhanced grinding rate was shown to be improved with the addition of grinding aids and Ultrafine grinding (P 80 ≤ 10 μm) has been proposed as an alternative to “unlock” gold from sulfidic refractory ores; however, the cost of size reduction to this level makes it applicable only for concentrates (Corrans and Angove, 1991; GonzalezAnaya et al, 2011), as is practiced at Kalgoorlie Consolidated Gold Mines, a joint venture Ultrafine Grinding an overview ScienceDirect TopicsJan 10, 2017 This is congruent with the findings of a previous study by Roufail (2011) on the fine grinding of ores with various levels of hardness using a horizontal stirred ball mill This study found that soft materials break down faster, reach their grinding limit faster, and start to aggregate earlier than do hard ones ( Roufail, 2011 )Ultrafine grinding and mechanical activation of mine All experiments were carried out on a two axis grinding machine (Moore 450 ) with a programmable resolution of 01 µm Figure 3 shows the machine with the work and grinding spindles During experiments, the grinding area is generously flooded with an emulsion coolant Figure 3 face grinding machine with wheel and work aerostatic spindlesInprocess force monitoring for precision grinding This paper proposes a fuzzy comprehensive evaluation of ultrafine powders, namely, yield and quality valuebased feature selection Three indicators reflecting product yield and quality were selected to construct a simple and practical fuzzy comprehensive evaluation protocol The weight set of the indices and the fuzzy evaluation set were calculated based on the analytic hierarchy process (AHP Parameter Optimization of Ultrafine Comminution Based on
