With varying fuel mixes and chemical composition, ball mills have an increasing challenge to deal with reject materials. Pyrites, rocks and tramp metals must be handled and removed from the process.
In older power stations it is more common to see hydraulic type mill rejects/pyrites removal systems using water and jet pumps to ensure enclosed transportation to reception tanks or ash ponds.
Working with the industry to reduce water contamination to the environment Clyde Bergemann offers dry solutions for extracting mill rejects. These solutions use pan type mechanical conveyors encapsulated within an explosion proof casing to ensure effective and safe operation while transporting the reject material to containers of bulk silos for onward disposal.
Issues around explosions and ATEX are without doubt also accommodated by Clyde Bergemann engineering and technology.
