Non-dredging Low-Speed bucket elevator for lifting large-sized material. Elevator with two round link continuous chains and toothed wheels. The chains are anchored to the sides of the buckets to ensure central discharge aligned with the bucket elevator. The main features of the bucket elevator include the following:
– standard dimensions (i.e. bucket width) of the same series as for high-speed elevators, starting from 315 mm
– non-dredging continuous pocket buckets with overlapping edges, equipped with bushings for connection to the driving pin
– drive wheels with exchangeable teeth for driving the chains
– return wheels with hub and smooth rings
– high-grade alloy steel continuous chains with long strands
– couplings for connecting the chain strands
– bucket driving pin, one end of which connects to the chains
– central feed inlet on idle station
– central discharge outlet under drive station
– standard tensioning system with contrast springs, pair of threaded bars and adjustement nuts
Type of feed system: central
Type of discharge: central gravity

Drive station
These bucket elevators can lift large-sized lumps of material (even up to 400 mm), thanks to direct loading into special “pocket” buckets without any dredging
The picture shows the drive station of an ETR bucket elevator during installation. Note how the “pocket” buckets are joined together and ensure gravity discharge in the central zone of the drive station

Boot station
Lower section of the bucket elevator comprising the central feed inlet. The special feed system configured at the centre of the boot station, allows for directly feeding the buckets without dredging thanks to a suitable hopper that protects the return shaft. In this way, even exceptionally large sized lumps of material can be lifted
