with rubber block chain bucket conveyors by Nerak Wiese Ltd
ucket elevators are the proven solution for rapid and secure handling of bulk materials. The UK manufacturer and vertical elevation specialist, Nerak Wiese Ltd., supplies both continuous bucket elevators and pendulum bucket elevators to meet a range of handling needs for the milling & grain sector.
Horizontal, vertical or inclined
Both types of elevator ensure gentle handling of bulk goods in high-throughput applications from one or more feed points; the difference between them is essentially that the continuous bucket conveyor is suitable for single-discharge applications while the pendulum bucket conveyor is designed for applications with multiple discharge points. For both solutions, the conveying paths can be horizontal, vertical or inclining without any additional transfers.

Unique rubber chain
Many of the advantages of Nerak’s bucket conveyors stem from the company’s unique rubber block chain. Simon Musgrave, Sales Director for Nerak Wiese Ltd., explains, “The rubber chain achieves its high tensile strength from embedded vulcanised steel cables. With a link-free design, it ensures quiet operation and does not suffer from chain stretch.” He continues, “In terms of maintenance, the design is wearresistant, avoids the need for lubrication and provides corrosionfree operation – so the drive system has very low maintenance needs. Another advantage is energy efficiency – and hence a very low carbon footprint – due to the absence of friction.”
Robust buckets
The bucket elevators consist of two endless and parallel rubberblock chains with plastic or steel buckets running between the two. For the continuous bucket elevator, the buckets are connected by flexible strips to create a gap-free conveying system. In the pendulum solution, the buckets are suspended in ball
