How to control the processing capacity of belt press?

Any belt press has a large capacity demand, there are two requirements, data refer to strategy:
A. large handling of dry solid loads, i.e. Larger nonvolatile solid components are processed per hour, compared with kgds (dry solids);
B. large processing hydraulic loading, sludge into the equipment, in m3 / h, said it and mud concentration (solid) product dry solid load. Under normal conditions of sludge concentration, it should be ensured that the calibration theory of dry solid load equipment of larger processing equipment manufacturers is 70% - 70% load, so as to prevent the equipment utilization rate from being too low, prevent the equipment from running under high load for a long time, form loss, and shorten the repair cycle. If the load of the equipment is too large, no matter how to improve the dosage of flocculant, it will not make a better therapeutic effect, which shows that the degree of mud biscuit is not ideal, the solid of supernatant is on the high side, and the speed of economic recovery is declining, because the supernatant overflowed from the sediment brings equipment wear, damage to dynamic balance, and oscillation. In some cases, because of the sludge concentration added, according to the original flow into the sludge, the practical equipment can accept the effect of mud load index reduction. Then gradually reduce the frequency of mud, timely investigate the effect, the effect is stable, and then continue to control the economic flow. On the contrary, when the sludge concentration decreases, it will be gradually added to the sludge flow, together with the metering pump flow adjustment. If the sludge concentration is too low, although the equipment is boring, the solid load is not high, but the hydraulic load is very large. Because the low concentration sludge is loaded in high hydraulic pressure, the equipment can not be useful. The thickness of the sludge layer will overflow a lot of supernatant, which directly affects the treatment function and treatment power. The reason for low concentration of sludge, such as thickening sludge tank, is better not to be treated by thickening treatment (such as thickener thickening after treatment), or with high concentration of mixed sludge (as) pond sludge dewatering treatment. The frequency of the mud pump will be reduced by preventing the excessive torque caused by the overload of the centrifuge due to the large mud load. This situation is mainly when the mud concentration is added, but it is still entering the next process
