ABSTRACT:
A system for producing a suitable fuel from waste material including a dispersion tank in which is located a rotary dispersion and agitation system comprising external vanes, rotary and stationary plates having opposing faces fitted with intermeshing shear blocks, forming an attrition zone therebetween for grinding and dispersing solids in a liquid blend stock. A method is provided for varying the displacement between the shear blocks to control the fineness of the grinding of the waste material. A method is provided for discharging metal from the dispersion tank and a pump 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 auguring waste material from the drums. The present invention also provide a method of 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.
