Armoured chain conveyor for salt mine

21st February 2013


KD Maschinen of Germany, has commissioned an AUMUND armoured chain conveyor (type PKF) for a German salt mine.

The unit has a centre distance of 13.5 metres and conveys 150 tonnes of potassium chloride per hour.

The AUMUND conveyor was chosen owing to its low build-height. As the unit will be employed underground to extract potassium chloride (road salt) from an intermediate bunker, the footprint and in particular the build height were deciding factors.

The total weight of 22 tonnes will be packed in handy-sized units, delivered to Breitenworbis in northern Thuringia and then be transported, piece by piece, through the depths of the mine shaft prior to reassembly. 

The tension element of the armoured chain conveyor consists of especially quenched and tempered round steel link chains. Three chain strands are used in total. With the related scrapers, which are also quenched and tempered, they achieve a discharge width of 1,000 millimetres. The material is conveyed in the upper run on a wear-protected base plate. Spillage is received in the empty lower run and conveyed back into the transport flow.
