Drive technology for conveyor system
Process reliability in the salt store
Rheinberg, around 60 kilometers from Düsseldorf, is home to the Borth rock salt mine and salt works. Between 7,000 and 8,000 tons of salt are mined and processed there every day.
The plant is operated by K+S, Europe's largest salt producer. The salt extracted from the mine is first stored temporarily before it is used as road salt, among other things. Borth has a storage capacity of more than a quarter of a million tons of salt: 180,000 tons in underground bunkers and around 70,000 tons in a warehouse. It is precisely here, in the warehouse, that a drive solution from RUD ensures the trouble-free feeding of salt into the hall. A mobile belt stacker has been optimized, which now runs failure-free and with low maintenance thanks to the robust RUD Tecdos round steel chain and the RUD Tecdos Omega Drive system.
The chain and drive were integrated into the existing steel structure. The principle of the Tecdos drive system is as simple as it is revolutionary: the Tecdos Omega Drive is attached to the SEW motor of the system and pulls itself along the horizontally tensioned Tecdos round steel chain over the entire travel distance of around 70 meters. This is how it moves the belt stacker back and forth. The limited space available and the statics at a height of 20.7 meters posed a challenge during the construction of the conversion. The chain on the belt stacker is a Tecdos Premium round steel chain made of case-hardened steel. The conversion and commissioning of the optimized belt stacker took place as part of an annual turnaround at the K+S plant in Borth. The conversion was installed and put into operation within a week.
