Bucket Elevator Design Considerations
Buckets are designed and arranged in a way that allows the back of each bucket to serve as a discharge surface onto which the previous bucket's material passes, making its way to the discharge chute via gravity. The image above illustrates the operation of a continuous-style bucket elevator. Note how the material is fed via a chute and ...
Chain Conveyors
If the calculated speed "v" is greater than the limit speed for aprons, the skirt height "h" must be increased. The drives allow variation of the speed to match, which is v = 0.03 m/s – 0.16 m/s (0.1 – 0.5 ft/s). For different capacities, can be used variable speed DC, AC and hydraulic motors.
Bucket elevators: A comprehensive guide
Centrifugal bucket elevators: These are the most common type and are ideal for handling heavy, abrasive materials. Centrifugal force is used to discharge the material from the buckets, making them suitable for smooth, fast handling. ... The speed at which the buckets move affects the handling capacity and overall performance of the elevator ...
Calculating the Product Throughput Rate of a Bucket Elevator
Bucket speed = 15 m/minute, bucket pitch = 0.25 m/bucket (or 4 buckets/m), bucket working volume = 0.005 m3 (or 5 litres) 15 m/minute x 4 buckets/m = 60 buckets/minute. Substituting in the bucket working volume we get: 0.3 m3/minute of volumetric throughput capacity. As the product handling industry work using throughput capacity per hour, we ...
Conveyor Chain
PUSHER CONVEYORS. Where chain is used with pusher attachment plates, to move loads along a separate skid rail (e.g. billet transfer conveyors), then there will be an extra load in the chain due to the reaction in the pushers. This load can be calculated by the following formula: Reaction Load Pull PL. = μm W. hu μc.
