<p>This invention provides a system for removing surface moisture from granulated coal or other materials in particulate form, the system comprising a dryer, wherein the dryer has: an in- feed (1) for material particles; an in- feed (3) for entrainment gas (suitably air) to provide dilute phase gas entrainment of the particles; and turbulence - inducing means (5) configured to subject the flow of gas - entrained particles to turbulence to strip water from the surface of the entrained particles. The system is highly efficient and economical to operate, requiring no external heat input and yet achieving a high drying effectiveness</p> |
