ABSTRACT:
Apparatus for and method of reducing spherically shaped fluid coke waste by-product pellets into a pulverized condition for use as a fuel in which there is a first grinding and pulverizing mill initially receiving the waste material which, because of its spherical shape is difficult to pulverize, and accordingly the waste material is transported to a second grinding mill where its spherical shape is altered to render it more easily pulverizable upon return to the first grinding mill where the final pulverizing of the waste material takes place prior to discharge to a point of use which may be to directly fire a furnace, a boiler or a kiln. The waste material is usually rather wet and requires drying so as not to choke the grinding apparatus, and for this purpose heat generated during the burning of the pulverized waste material is returned to the apparatus for the purpose of drying the waste material during its processing in the respective mills.
