    摘要: A waste treatment system which is capable of handling materials of widely different physical characteristics such as glass, metal, and fibrous and plastic waste, incorporates a rotor rotatably mounted in a waste receiving vessel, the rotor being adapted to fracture brittle material, compact malleable material, and otherwise pulverize the frangible waste to a particulate form small enough to be extracted through a perforated plate. The rotor also circulates the material in a slurry form within the vessel in a vortical pattern so that the waste is repeatedly treated until it is ejected from the vessel. A series of space attrition bars are mounted outwardly of the rotor to provide an annularly shaped, discontinuous attrition surface, and hammers or flails are pivotally mounted on the rotor to reduce into smaller pieces materials which are flung upon or between the attrition bars by the rotor. Where the waste material contains a high proportion of rags, tubing and other stringy material, a rotating chopper blade is provided to chop this portion of the waste into smaller pieces which are more readily handled by the rotor and flails. Waste materials which are not readily reduced to a pulverized state by the system are segregated from those which are and removed separately.

    摘要: Apparatus for pulping paper making stock at high consistencies, e.g. 10 percent to 25 percent solids, includes a cylindrical tub and a rotor constructed and arranged to apply primarily pumping force to the stock which causes it to travel outwardly to and upwardly along the tub wall. This climbing stock is continuously subdivided and directed back into the tub, and a feed screw extending vertically upward from the rotor assures continuous circulation which develops zones of intense hydraulic sheer constituting the major force for effecting the desired defibering.
