· The take-up device in a conveyor belt system has three major functions: To establish and maintain a predetermined tension in the belt. To remove the accumulation of slack in the belt at startup or during momentary overloads, in addition to maintaining the correct operating tension. To provide sufficient reserve belt length to enable re-splicing

SC = 3.75 * 1.50 * 323. SC = 1817cu.ft. This selection capacity value will be used in the capacity table, for calculating correct size and speed. In the appropriate column, under 30% A loading, we find that a 14″ conveyor, at the maximum recommended speed will convey 2194 cu. ft. per hr. or 21.1 cu. ft. per revolution.
