RUD conveyor technology - Optimized material feed of free flowing products at bucket elevators Fertilizer plant
Description of the problem:
For a reliable elevator operation the material feed is of utmost importance. Mostly the inlet flange at the elevator reflects the limit of responsibility between customer and manufacturer. Mistakes ahead of the machine result in problems in the machine:
Off-centered material
→ Asymmetrical bucket load, different chain load/ elongation (chain elevators), misalignment of buckets,hence problems with chain reversions, misalignment of belt (belt bucket elevators)
→ Risk of operational reliability/total system break-down.
Too high feeding speed
→ Splashing of material out of the buckets
→ calculated bucket load cannot be reached
→ designed elevator capacity drops
→ Risk of operational reliability/total system break-down.
RUD Solution:
Installation of a rock box ahead of the elevator inlet:
Material is dammed by a defined rock box geometry depending on given parameter (angle of repose, falling height, slide length, angle of intake, etc.)
Result
=> Better material distribution over the whole intake width (bucket width).
=> No splashing of the material out of the buckets.
=> Achievement of the required capacity by means of optimal bucket load.
=> Optimal operational reliability by avoidance of machine/system-overload.
