Slip rings are used in circular reclaimers and stackers which are used for loading and unloading large amounts of different bulk materials. Reclaimers/stackers are in use e.g. in ports and terminals. In power plants reclaimers are used for solid fuel and biomass handling.
Combinent has produced large slip ring units for silo and open yard reclaimers/stackers since 1990’s Combinent slip rings are complete ready to moun units. Maintenance need for the slip rings is very low and many of the Combinent slip rings in power plants have been running already for over 20 years with no problems.
