Abstract
Disclosed is an apparatus for separating a pellet-like product from fines (e.g., dust) mixed therewith. The apparatus includes a vertically disposed housing having an upper fines outlet and a lower product outlet. An inlet conduit passes through the housing intermediate the fines outlet and the product outlet and terminates in an upwardly facing inlet nozzle. The inlet conduit receives quantities of product and fines along with a propellant fluid (e.g., pressurized air). An impact baffle is supported within the housing having a concave impact surface that faces the inlet nozzle and that is positioned to intercept the product pellets issuing from the inlet nozzle. The impact baffle is sized and supported to provide an annular flow oriface for the propellant fluid (and fines mixed therewith) between the impact baffle and the housing. A second baffle, supported in the housing adjacent and above the impact baffle, is shaped to define an annular flow conduit that increases in cross section in a direction away from the annular flow oriface. Valve means control the exit velocity of the fines and propellant fluid through the fines outlet.
