'A sheltered conveyor brings the Disco product from the carbonizers to this sheltered mechanical cooling wharf. A method of careful cooling in motion prevents spontaneous firing of the fuel and avoids injury to the structure of the product. The wharf is contructed of a series of grates, which are successively raised and lowered in a wavelike manner to keep the Disco product in motion and convey it slowly, while it is being cooled, down to the discharge end of the wharf.
'The Georgetown Preparation Plant was the worlds largest commercial coal preparation plant, having a capacity of 1,500 tons per hour of raw coal, or 1,275 tons per hour of clean coal. The plant has facilities for dumping bottom-dump tractor-trailer and end-dump trucks, and for rotary and bottom dumping of railroad cars. Coal from these dumps goes into a 1,500 ton bin, from which it is conveyed on a 641 foot belt conveyor to the primary shaker screens. Whereas the conventional coal perparation plant provides only one circuit for all coal washed, the Georgetown plant is unique, in that it provides three separate washing circuites, each of which is designed to most efficiently clean a certain size fraction.'
