Drum reclaimers applied 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 drum travels on rails on four undercarriages. The travel drive is realized using 8 drive units (2 per undercarriage). The undercarriages are equipped with rail tongs, one per rail, to secure the during out-of-operation wind, and with rail cleaner on both sides of the travel.

The drive unit consists of a gearbox with a servomotor controlled by a frequency converter. This servomotor operates in all the required ranges of travel speed, thus it is not necessary to use both independent motors for operation and transport traveling. The drive units are mounted vertically on the external traveling wheels of the undercarriages. Incremental sensors are used for the accurate positioning of the machine.

The spreading device provides a transverse oscillating movement, thereby it spreads a surface layer of material and shapes a profile of material on the stockyard to ensure uniform filling of buckets. A spreading device tilting angle can be manually adjusted depending on an actual state of material distribution on the stockyard. The machine is fitted with two spreading devices, one per side of the machine’s travel direction.
