Bucket elevator with EVN rubber conveyor belt
These are bucket elevators with rubber bands, the buckets of which are connected and bolted to a special rubber band, driven by frictional force generated by an electrically controlled drive drum.
Bucket dimensions (liters), pitch (distance between the centers of the bucket) and lift speed determine the volumetric capacity or lifting capacity of the elevator (in cubic meters per hour).
The shape of the bucket sides affects the maximum speed that can be achieved in a peripheral unloader with any given upper drum diameter to avoid excessive recirculation of material falling into the bottom of the elevator.
For large machines, speed is limited to a maximum of 1.6 m / s (96 m / min) to increase bucket size, resulting in exceptional flow rates and lower bucket costs with fewer buckets.
To balance the belt on the move to avoid its displacement from the drums, the tensioning unit of the elevator uses a special parallel tensioning system, consisting of a pair of pantographs with a counterweight.
