Coal beneficiation: Policy priorities for India | ORF

The economics of coal washing in India depends on how the heat value in rejects can be utilised. One of the most common strategies is to use rejects in a pit head power plant using fluidised bed combustion technology (FBC) that is capable of burning high ash coal with gross calorific value of 1,800 – 2,000 kcal/kg.In coal preparation, screening machines serve two purposes: sizing and media recovery. Oftentimes, the initial screening is performed by a scalping screen located outside the plant. This prevents the screens inside the plant from becoming overloaded. The deslime screens make the next cut and most prep plants size to minus 1 mm.Selection Tips for Vibrating Screens - Coal AgeGet Contact details & address of companies manufacturing and supplying Screening Plants across India.
