thus control the spacing between the shear blocks to control the fineness of the grinding of the waste material means is provided for discharging metal from the dispersion tank and means is provided for circulating liquid from the dispersion tank to an accumulation tank and for recirculating the liquid from the accumulation tank to the dispersion tank feeding systems are provided for delivering solid waste material to the dispersion tank and include systems for grinding drums containing waste material expressing waste material from the drums and augering waste material from the drums the present invention also provide a method of is processing waste material and a blend stock which provides a suitable fuel and includes the steps of grinding the waste material in a tank containing the blend stock with the grinding being in at least part provided by the coaction between a rotating impeller and a stationary plate so that the degree to which the waste material is ground is controlled by controlling the spacing between the plate and the impeller application_number US 80284897 A description the improved apparatus of the present invention is illustrated partially in fig1 wherein the dispersion unit 10 is shown with the accumulation tank 12 and the elements providing connections therebetween the feeding of the solid waste materials is more completely illustrated in the other drawings as hereinafter described dispersion unit 10 includes tank 14 which includes solids inlet connection 16 in its upper end recirculated fluid inlet 18 in its upper end and connecting to line 20 and discharge 22 connected into the bottom as hereinafter more completely shown and described and connected to discharge line line 20 connects into the lower portion of accumulation tank 12 and through recirculation pump 26 so that fluid in tank 12 can be recirculated to.
