Bucket Elevators
Robust and of high servicability: Our bucket elevators are second-to-none.
Künzel bucket elevators are used for the vertical conveying of grain, malt and other bulk materials. They are available in several standard dimensions for a wide capacity range or can be individually designed and manufactured as special versions for many different applications and conveying capacities.
Our bucket elevators come with a choice of normal steel version with painted or galvanised surface, and a stainless steel version. The elevator foot is fitted with a belt tensioner. The actual belt runs in a caged pulley in the foot in order to avoid caking which could otherwise impair correct operation.
With the selection of bucket type, number of buckets per meter and by defining the belt speed Künzel experts can optimise the operating parameters for the individual application and the required capacity.
