The coal industry, of course, faces a number of growing challenges. In some cases success means reducing maintenance with a robust fluid bed dryer, or improving automation through advanced instrumentation, process control, or dynamic simulations of mining operations. Other times, water recovery can be a significant competitive advantage.


500 tph operation. A 17% reduction in energy use was estimated by employing dry separation technology at the mine site, which also reduces the amount of impact land and reduces the size of slurry impoundments. Coal recovery from coarse coal waste generated from past mining operations was also evaluated at two sites.
