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. Since the x-ray technology is capable of detecting atomic differences in the rock, the almost pure carbon in the coal is
