'On the top level of the heat drier building showing, from left to right, the motors, blowers and tops of the cyclones. The vertical tubes are exhaust stacks for the waste heating gases and moisture. The driers themselves are long, vertical tubes, located beneath this deck. A blast of hot gasses dries the coal and the cyclones then separate the coal from the waste gasses and moisture. Purpose of the drying operation is to reduce the moisture acquired in coal washing, 'or from the atmosphere during storage on the stock pile', and provide the processing plant with a uniform charge material.
'The Plus 6" coal will be crushed to minus 1.5" and two 16,6" Chance Cones will wash the 6 x 3/8 coal. Current production of approximately 1800 tons per day is crushed to minus 1.25" then trucked to the storage yard of the new Kammer Power plant.'
'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 Prepatation Plant is here viewed from the north, showing the main entrance. Landscaping has begun and the company will build a sizable parking lot in front of the plant with auxiliary lots near the scale house (off the picture to the left) and at the track level in the rear. The enclosed raw coal conveyor and the refuse loading bin are shown at the right. This plant will serve as a central preparation facility for the strip mining and some of the underground mining operations of the Hanna Coal Company, Ohio operating division of Pittsburgh Coal Company. With a capacity of 1,500 tons of raw coal input per hour, Georgetown is the largest coal cleaning plant in the commerical bituminous industry. It has three cleaning circuits and five types of facilities for drying the coal. Integrated with the plant operation are special systems for cleaning and recirculating the water, thereby avoiding stream pollution, and for elimination of air pollution.'
