dry dry beneficiation of coal review

Dry coal preparation without the use of water STEINERT

An effective means of dry coal beneficiation is offered by our STEINERT XSS T X-ray sorting system based on 'dual energy' x-ray transmission. This allows ash content to be reduced without the use of water, while specific contaminants such as sulphur can be accurately removed.
