• Wet deslagger

    Level control in the wet deslagger fulfils two important functions: First and foremost, it controls the water level, which cools and removes the hot slag. Secondly, it maintains a hermetic seal on the furnace chamber - a reliable level measurement avoids unwanted air that would otherwise get sucked into the combustion chamber.

    The ATOX Coal Mill can grind and dry raw coal with up to 25 percent moisture level. By adjusting the gas flow stream with the nozzle, you can deal with more 'sticky', high-moisture feed materials. There is an oversized nozzle ring and separator that is available to make this adjustment. A fine operation.
