Abstract: Partially wet organic fibrous material is centrifugally impacted in a hot exhaust gas atmosphere such as flue gas to defiberize and dry the material. Then the material is separated from the hot exhaust gas by fluid energy. In one form of the invention, the separated material is burned in a prime combustion zone thereby producing hot flue gas which is fed back to the centrifugal impacting zone.

Abstract: A stable combustion fuel emulsion of a petroleum fuel having a small percentage of water dispersed therein as droplets of a size of about 0.5 micron, or less, formed by high energy rotary impact milling the petroleum fuel and water together.

Abstract: Rotary processing apparatus is shown having a horizontal rotor made up of a number of flat annular plates secured together to which material processing members such as centrifugal impactors are releasably secured. Stator processing members or impactors are shown which are adjustable from outside the rotor housing. In another form, a rotor operating in a vertical plane and having processing members or impactors on both sides has material to be processed fed to it separately on each side. In both forms, reinforcement of the rotor housing may additionally be achieved by providing a plurality of generally flat annular members secured together and to inside surfaces of the rotor housing. Rotor impactors for the second embodiment have two processing ends and are provided with simple slip-in means for insertion into place through apertures in the laminated rotor.

Abstract: This apparatus comprises a supporting frame for two upstanding chutes though which flowable, particulate materials may be applied. These materials flow down the chutes though an opening in the top skirt plate supported by the frame and into a processing area such as the rotor of a centrifugal impact milling machine. A motor is mounted for horizontal pivotal movement relative to the chutes and drives a vertical spindle located between the chutes that is connected to the rotary processing member below the skirt such as the rotor of a centrifugal impact machine. A hopper is provided to swing pivotally downward below the rotor in a damped fashion, the pivoting mechanism being fixed to the top skirt and enabling one man removability of the hopper to allow access to the rotor or the inside of the hopper for cleaning, maintenance, etc.
