- Chance Cone Feeding Coal
- Description:
- '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.'

- Heat Drier Building
- Description:
- '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.
