Optimizing recovery using on-line ash analyzers or sorting for dollars
The quest for profitability in the complex coal industry requires continual examination of common practices looking for better and more cost effective methods of performing these tasks. As the available coal reserves become more difficult to mine and the quality decreases, this examination process grows in importance. Over the past fifteen years, we have all seen major changes in the methods used to mine, clean and load coal in an attempt to increase the bottom line and proliferate a safer work place. The long wall mining method has greatly increased the profitably of the larger mines that have the reserves and the seams suitable for this method. Bigger and faster conveyor belts have increased loading capacities and decreased time spent performing the task. New technology in the cleaning and preparation of coal has also assisted in increasing yield and thus decreasing the final cost of a ton of coal. What about the smaller mines that do not have the mining conditions or reserves for a longwall or the monetary resources to upgrade belt lines and preparation plants, they to must remain profitable. The on-line ash analyzer is one answer that is not only for the smaller mines but can show quick and substantial returns for the larger operations. The on-line ash analyzer is a nuclear device that is mounted directly on the conveyor belt to produce an instantaneous ash analysis on the coal as it moves beneath the detector. The on-line ash analyzer is described.
