Heavy duty drum reclaimers for coal reclaiming in coal terminal stock

The drum reclaimers, traveling a horizontal runway, are designed to service parallel storage piles in bi­directional operation in an open stockpiles/yard type storage. The must have 3,500 tons per hour capacity to handle <300 mm sized coal.

The substructures functionally connected to the drum consist of a rail track, electric supply cables, water supply hoses for the sprinkler system, and end bumpers.

The machine is running on running wheels that are mounted on the undercarriage supports. Each undercarriage support has a driving and a running wheel. The drive works with shaft-mounted bevel gear. The driving motors are frequency controlled. The side guide of the undercarriage is realized with a floor railhead, which transmits the lateral forces onto the rails. The undercarriages are equipped with a skew control. The skew is corrected by reducing the speed of the prior running undercarriage. The machine is equipped with a limit switch, which is mounted at the outer end of the lower undercarriage support. The limit switch terminates the moving range of the scraper in both directions. The angle encoder for the path measurement of the scraper is located on the loose running wheel of the lower undercarriage support and detects the position of the machine.
