An effective means of dry coal beneficiation is offered by our STEINERT XSS T EVO 5.0 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. Since the x-ray technology is capable of detecting
