Investigation and Evaluation of Jigging Separation Features

The process of enrichment in a jig has usually been described and analysed using particle density as separation feature. However, degree loosening the bed is affected by, inter alia, terminal free settling velocity which turn by size, shape particle. Therefore, clearly characterises feed transferred to for process. Taking comprehensive geometric (particle size shape) physical properties density) into account comes down calculation velocity. therefore complex feature comprises three basic features density, shape). This paper compares effects coal fines jig, two cases: when commonly applied Particle velocities were calculated selected fractions: –3.15+2.00, –10.00+8.00 –20.00+16.00 mm based on industrial testing detailed laboratory tests consisting determining projective diameter volume dynamic coefficient. drawn partition curves variants, i.e. taken argument fractions, allowed calculate compare precision indicator. With use statistical test, assumption independence random variables distribution components included during was verified.
