Feed conveyor for bulk material - has stationary weighing machine arranged before feed discharge end to vary conveyor speed

摘要

The equipment evens out bulk material delivered in an iregular stream by a feed conveyor onto a movable intermediate one. The travel speed is varied dependent on the reading of a belt weighing machine. The material is then directed onto a discharge conveyor. The weighing machine is on a stationary mounting before the discharge end of the feed conveyor and the travel speed VF of the intermediate conveyor (B2) is determined from VF = (L1-L3)/(Q2-Q3) and its transport speed (V2) from V2 = L1/Q2-VF where L1 is the detected transport rate L3 is the predetermined transport rate of the discharge conveyor (B3) Q2 is the predetermined constant belt loading of the intermediate conveyor Q3 is the predetermined belt loading of the discharge conveyor.
