Conventional coal washing plants generate clean coal with 1518% ash content and 3550% yield by several physical beneficiation techniques. Handling and disposal of the rest of 50% reject is an environmental concern and hence, alternate processes for utilization of high-ash washery rejects are of high importance. Their compact, modular design provides flexibility when building or upgrading your plant. Double start spirals reduce the requirements of height and floor space in a plant, and reduce capital and operating costs. The MX7 spiral separator is ideal for difficult-to-wash coals, improving the overall efficiency of tougher separation applications.
