'The sheltered construction of the processing equipment makes it difficult to photograph the coal in flow through the circuits, but this is a flash of the raw coal feed pouring into the 16.5 foot Chance cone. In this cone-shaped vessel, a mixture of sand and water is kept at a controlled gravity by agitation and by control of the proportions. This gravity is set to separate the clean coal from the refuse. The lighter coal is floated on top of the mix and guided to a discharge to continue its processing, which includes desanding, scrubbing, sizing, and moisture removal. The heavier refuse meanwhile sinks to the bottom and is passed to the refuse disposal system. This large cone has a capacity of 500 tons per hour.'
Raw Coal Conveyor Belt at Georgetown Preparation Plant
Description:
'This enclosed raw coal conveyor belt starts the coal on its journey through the Georgetown Preparation Belt. The belt is 641 feet long and moves at a speed of just above 10 miles per hour. The coal is taken to the top of the plant, where it is given a preliminary sorting by size and then sent through one of the three cleaning circuits incorporated in the preparation system.'
'Shown here are the loading booms in action. Each of the five loading tracks is served by a loading boom, and the loading system is interconnected so as to permit blending of sizes and loading of any size group on any track. The loading booms gently lower the coal into the cars with a minimum of opportunity for dust or degradation. The loading facilities are sufficient to permit the loading of a car every two minutes. The adjoining track system permits rapid assembly of trains, interchange between the two railraods, and sufficient trackage for the storage of 858 railroad cars of 70 ton capacity.'
