Influence of Feeding Speed on Gas Flow Acceleration Classification and Drying for Filter Cake Treatment

[摘要] As solid waste processing facilities deal with increasing amount in combination with enhanced environmental pressures, gas flow acceleration classification and drying is becoming one of the promising methods for filter cake treatment. The influence of feeding speed on gas flow acceleration classification and drying for filter cake treatment was investigated in terms of classification efficiency, purity and recovery proportion. The optimal feeding speed was 0.8 kg/h was the optimum feeding speed; at the same time, the diatomite recovery proportion was 41.7%.The present study could also provide an experimental basis for optimizing filter cake treatment process.
