A waste mangler system, optionally provided with classification means, for processing garbage, municipal waste, and the like whereby to mangle or break up compacted garbage and other materials, break open bags and bales, and otherwise treat the refuse for a flailing-type reduction. The machine is vertically oriented and includes a rotor having rapidly revolving cross-arms, mounted to a central shaft, which are provided with rigid impact blades and flail elements. The impact blades include rearwardly tapered leading edges so that debris may slide outwardly thereon under the action of centrifugal force to approach the area of reduction proximate the flail elements used. The material descending through the drum of the machinery is deposited down to suitable conveyer means that may be coupled to air classification or other means for material separation and further processing.
Waste mangler structure including, in combination, essentially vertically disposed cylindrical structure, and a rotor journalled for rotation centrally within said cylindrical structure, said rotor having auger means cooperable with said cylindrical structure for forcefeeding received materials downwardly within said cylindrical structure, said rotor also having rigidly affixed cross-arm means disposed beneath said auger means for impact-loosening and reducing compacted materials received from said auger means, and drive means coupled to said rotor for revolving the same, said cross-arm means comprising a series of inner, impact ripper blades and a series of outer flail chains respectively secured to said impact ripper blades.
In combination, a tubular structure having a feed end and a discharge end, a rotor centrally journalled within said tubular structure and having a longitudinal axis of revolvement, said rotor including an auger proximate said feed end and cooperable with said tubular structure for positively advancing materials fed into said feed end in a direction toward said discharge end, said rotor also being provided with radially extending rigid arms downstream from said auger and having outer extremities and also flexible elongate flails secured to said rigid arm outer extremities, the overall length of said arms with said flails exceed the distance between said longitudinal axis and said tubular structure, whereby said flails can impinge against said tubular structure.
