The bag dumping and feeding station of the RNT series enables efficient unloading of bulk materials from bags, sacks, small containers and bins. The powder, granulate or bulk material is emptied into the hopper and sucked into the conveyor line from there. It can then be transported by vacuum conveying through a pipeline over a distance of up to 100 metres to a process system (e.g. mixer, reactor, filling machine, etc.) or into a container or silo. Gravimetric emptying into a system directly below the emptying station is also possible.
