原始语种摘要: Abstract(#br)Beneficiation of fine coal of size 300×150μm was investigated in a laboratory Kelsey jig. A number of process variables were studied while others were kept constant. Silica sand of size −1.68+0.85mm was used as ragging material to prevent pegging of the internal screen. The thickness of the ragging bed was established to be most crucial in controlling the separation. Rotational speed significantly affected the porosity of the ragging bed and particle momentum which had a contrasting influence on process performance. Pulsation rate determined bed dilation and misplacement of heavier particles. A slip velocity based estimation of the particle...
