Underflow control for nozzle centrifuges

摘要: In a centrifuge for the separation of solids from liquid in which concentrated are discharged radial nozzles (26, 28) at periphery, there is provided underflow discharge control apparatus (30) senses an in-creased concentration (24) and adjusts flow recycle stream as result thereof to prevent sol-ids spilling over into effluent overflow (22). A sensing chamber (40) module (42) having interfer-ence device (102) utilized measure set level backup. Any alteration said detected by sensor (60) sends signal indicator (62) turn controls opening closing recyle line valve (46) con-trols underflow.
