ABSTRACT:
A method for disposing by incineration of oil contaminated waste material after removal of solids of various kinds by performing multiple steps in its handling wherein the composite material is first subjected to a first classification step for extracting a high percentage of contaminant free material. After subjecting the material to a second classification cyclone where the gases that are used to transport the ground matter can be separated while the solids are subjected to classification by the use of a vibratory screen where the paper, fluffy waste, and similar material can be separated from the smaller and harder particulate components. The separated components are subjected to individual impact grinding steps prior to being recombined in the combustor where incineration takes place. The gases separated in the cyclone step for moving the residue of material into an incinerating combustor, and ambient air is delivered to the incinerator for establishing sufficient oxygen to support combustion at a temperature that will sanitize and destroy odors in the waste material and after the sanitizing step in the incinerator, the gases are exhausted through suitable heat exchangers and filtering medium while the residue material is fused at high temperature into stable pellet form.
