A bowl having a bottom discharge opening is mounted at its periphery on a frame for rotation about an upright axis. A discharge gate is mounted on the frame under the bowl for movement along the bowl axis to control the discharge opening. A top inlet opening directs material to be processed onto the discharge gate. This material is propelled in a straight line radially up the inner wall of the rotating bowl by centrifugal force between radial vanes. Stationary guide vanes are suspended within the interior of the bowl to intercept the material at the upper margin of the bowl and direct the material in streams which collide in the center of the bowl to mix and/or triturate the material. Turning vanes or discharge cups are mounted for movement into registration with the guide vanes to direct the streams toward the discharge opening when the discharge gate is open.
A material processing device comprising a frame, a bowl mounted on said frame for rotation about an upright axis, said bowl having an inlet opening, means for rotating said bowl, said bowl having an internal wall which is so shaped that when the bowl is rotated centrifugal guide vanes suspended in fixed position from said frame portion within an upper portion of said bowl whereby the bowl is rotatable relative to said vanes, each guide vane having an inner discharge end and having an outer end shaped and positioned to intercept material which has been moved upwardly on the wall of the rotating bowl, and said guide vanes being shaped and positioned to direct streams of said material from their inner ends toward the center of the bowl where said streams may collide to cause one of mixing and trituration of the materials, and in which the bowl has a bottom discharge opening, a gate for said discharge opening, and in which there are deflector means for directing material from the streams at the center of the bowl downwardly toward said opening when said gate is open.
A material processing device comprising a frame, a bowl mounted on said frame for rotation about an upright axis, said bowl having an inlet opening, means for rotating said bowl, said bowl having an internal wall which is so shaped that when the bowl is rotated centrifugal force will cause material to move upwardly on the wall, guide vanes suspended in fixed position from said frame portion within an upper portion of said bowl whereby the bowl is rotatable relative to said vanes, each guide vane having an inner discharge end and having an outer end shaped and positioned to intercept material which has been moved upwardly on the wall of the rotating bowl, and said guide vanes being shaped and positioned to direct streams of said material from their inner ends toward the center of the bowl where said streams may collide to cause one of mixing and trituration of the materials, and means for discharging the processed material from the bowl, and wherein said bowl has a bottom discharge opening, in which there is a discharge gate having an upwardly projecting portion, and means for supporting said gate for movement into and out of closing position with respect to said bowl and for rotation with said bowl when said bowl is rotating.
A material processing device comprising a frame, a bowl mounted on said frame for rotation about an upright axis, said bowl having an inlet opening, means for rotating said bowl, said bowl having an internal wall which is so shaped that when the bowl is rotated centrifugal force will cause material to move upwardly on the wall, guide vanes suspended in fixed position from said frame portion within an upper portion of said bowl whereby the bowl is rotatable relative to said vanes, each guide vane having an inner discharge end and having an outer end shaped and positioned to intercept material which has been moved upwardly on the wall of the rotating bowl, and said guide vanes being shaped and positioned to direct streams of said material from their inner ends toward the center of the bowl where said streams may collide to cause one of mixing and trituration of the materials, and means for discharging the processed material from the bowl, and wherein there is an annular bearing ring rigidly attached to the outer periphery of said bowl, and in which there is bearing means on said frame positioned to rotatably support said bearing ring whereby the bowl is rotatably suspended.
