I-B Conveyor


Characteristics of I.B Conveyor compared with the Chain Bucket Elevator

Items I.B Conveyor Chain Bucket Elevator
Impact at loading and wear on bucket As materials are moving with conveyor, there is no impact at loading. Wear is minimal. Bucket life is 3 to 5 times longer than outer buckets of the same thickness. Impact at loading is heavy, as material flows directly from loading chute into buckets. When buckets scrape spillage at bottom of case, uneven motion is caused, which may then cause buckets to drop off. Wear on buckets is heavy and life of buckets is short.
Impact at unloading Approximately 100% of mateials are unloaded and wear on parts other than the chute is extremely low. Wear is high on types which use the back of the preceding bucket for guided unloading, and thickness of bucket must be greatly increased. Spill of materials due to elevator's construction causes damage to lower parts. The level of damage greatly increases as the height of the elevator increases. Parts life is short.
Power Load Power Load is constant. Rotational resistance comes only from that of transporting of materials Power Load load fluctuates due to resistance created when materials are scrape-loaded into buckets. Uses 30 to 50% more power than IB Conveyor.
Tension control The floating lower drum unit acts as a tension weigh, which lowers in position as the belt stretches. Normally, adjustments of screws, etc, must be made by hand on a regular schedule.
Noise Except for the noise of materials flowing in the chute, noise occurrence is extremely low. Scraping noises produced at loading, as well as loud noises from material falling from bucket at unloading.
