20 years of Triboelectrostatic Beneficiation of Fly Ash

 · The increased mechanization in the underground coal-mining industry has increased the volume of fine size coal and waste (refuse) in the mined coal. Processing of run-of-mine (ROM) coal is generally done using water away from mine and in some cases the coal has to be transported a long distance to the preparation plant. Dry processing of coal can be economical as it will not utilize water …An attempt is made on coking coal fines dry beneficiation of below 2 mm size, with VSK separator consisting of advanced air cyclone. The results of these investigations reveal that simple size with 250 micron can give a product with 18% ash at 17.4% yield, whereas by using VSK separator the product obtained contains 17.8% ash with 48.1% yield ...With 18 separators in 12 coal-fired power plants across the world, ST Equipment & Technology LLC's (STET) patented electrostatic separator has been used to produce over 15 Million tonnes of low carbon product.
