To answer the call for increasing capacities, Aumund engineers and technicians have developed the triple chain bucket elevator Type BW-T. With this elevator three bucket strands are affixed to a common drive shaft running on four plummer block bearings.
Compared with three individual bucket elevators, maintenance and foot print is significantly lower. An essential precondition for the construction of a triple bucket elevator was the availability of a chain with a breaking load of 2450 kN that masters lift heights of up to 90 m. Furthermore, newly developed flow dividers guarantee simultaneous filling of all three parallel bucket strands.
In close cooperation with the Technical University of Magdeburg, Aumund developed a gravimetrically working chute that fills the buckets from three parallel outlets. Amund states that, while the state of technology up to date limited the application of such bucket elevators to heights up to 70 m and a mass flow of 2500 t/h, with the triple bucket elevator Aumund Type BW-T it would now be possible to offer operating ranges up to 90 m height and up to a mass flow of 4000 t/h.
