Centrifugal classifying system
Abstract
Abstract THIS DISCLOSURE RELATES TO A CENTRIFUGAL CLASSIFYING, OR PARTICLE SEPARATION, SYSTEM WHEREIN SOLID PARTICLES ARE ADMITTED TO A ROTATING DISTRIBUTOR PLATE. CENTRIDUGAL FORCE THROWS THE PARTICLES OFF THE PLATE RADIALLY OUTWARDLY TOWARD THE SIDES OF A CYLINDRICAL HOUSING, AND THUS INTO A STREAM OF AIR FLOWING UPWARDLY AND INTO A REJECTOR MECHANISM. THIS MECHANISM IS A CYLINDRICAL FAN OF THE "SQUIRREL CAGE" TYPE, HAVING A LARGE NUMBER OF VERTICALLY ALIGNED BLADES AROUND ITS CIRCUMFERENCE. AIR IS FED INTO THE HOUSING SURROUNDING THE REJECTOR DRUM AND FLOWS THROUGH THE BLADES TO A DISCHARGE CHAMBER LOCATED INSIDE THE REJECTOR, CARRYING WITH IT PARTICLES OF THE MATERIAL BEING THROWN OFF THE DISTRIBUTOR PLATE. THE SIZE OF THE PARTICLE ENTRAINED IN THE AIR FLOW AND CARRIED INTO THE DISCHARGE CHAMBER WILL DEPEND UPON THE RATE OF FLOW AND UPON THE SPEED OF ROTATION OF THE REJECTOR BLADES. THE PARTICLES NOT ENTRAINED AND THOSE PREVENTED FROM PASSING THROUGH THE REJECTOR BLADES WILL FALL TO THE BOTTOM OF THE HOUSING FOR REMOVAL, AND IN THIS MANNER THE DESIRED PARTICLES MAY BE SEPARARED FROM THE REMAINDER.
