For the dam in our area, lets say we buy a turbine and generator with an efficiency of 80%. Then the power for our dam will be: Power = (10 feet) x (500 cubic feet per second) x (0.80) / 11.8 = 339 kilowatts. To get an idea what 339 kilowatts means, let's see how much electric energy we can make in a year.

The ATOX® Coal Mill can grind and dry raw coal with up to 25 percent moisture level. By adjusting the gas flow stream with the nozzle, you can deal with more 'sticky', high-moisture feed materials. There is an oversized nozzle ring and separator that is available to make this adjustment. A fine operation.

Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

How a Rotary Kiln Dam Works. A dam in a rotary kiln works much like a dam in a river; material builds up behind the dam, forcing retention time and bed depth to increase. Material then spills over the dam, and discharges from the rotary kiln. Since most kilns utilize a counter current air flow, end dams are the most commonly employed type of dam.
