The difference in speed, determines the processing capacity and the degree of the biscuit. Improve the difference speed, slag quickly, increase the processing capacity, but the slag water content is high, the recovery is low, reduce the difference in speed, the increase of mud biscuit, show the helix torque, processing capacity is reduced.
Therefore, in order to meet the maximum processing capacity and the best processing effect of the contradiction, to find the best difference in speed, this value can be adjusted according to the actual situation, combined with sludge flow and mud biscuit degree, supernatant liquid status to determine. It is important to note that in the case of the same sludge flow and sludge concentration, the difference rate increases, the torque decreases, and the water content of the cake increases; Conversely, the differential speed decreases, the torque increases, and the water content of the mud cake is reduced. In principle, the maximum processing capacity combined with the best treatment of the principle to determine the difference in speed parameters, in the amount of flocculant to ensure within a reasonable dosage range, centrifuge speed fixed, the concentration of the slurry into a relatively stable situation, the equipment processing capacity and dehydration effect is entirely dependent on the difference speed control.
