ABSTRACT:
A non-blinding filter system for batch centrifuges utilizes a high speed injection nozzle to input wet particulate matter in the form of a slurry into a batch centrifuge in a manner that maintains turbulence within the slurry during the filling operation. Submicron particulate fines are suspended in the filtrate and settle out less rapidly than larger diameter particulate matter, thus a layer of coarser material can be laid over the filter media before the majority of the filtrate passes therethrough. A plurality of metering orifices retard the extraction of the filtrate such that the submicron particles are not forced through the layer of coarser material to the filter media with blinding consequences.
