Measure the distance between the two marks jog the system until the second mark is in the location of the first 0 mark then make your third mark down the length and then measure inbetween the marks again continue this process until your final measurement ends with the mark labeled 0
Since one horsepower hp 33000 ftlbsmin required conveyor drive power may be expressed in hp as follows te in lbs x v in fpm 33000 ftlbsminhp hp after calculating te it is important to calculate t2 slip slack side tension required to resist slippage of the belt on the pulley
Inclined conveyors hpp x bpmx f x s33000 effective tension pull needed to move belt and load horizontally e f x pm tight side tension total tension to move belt and load horizontally e 2 ee 1 slack side tension additional tension required to prevent slippage on drive pulley e 1 e x k operating tension
Understanding a basic conveyor belt calculation will ensure your conveyor design is accurate and is not putting too many demands on your system when the head and tail pulley are the same size ldd2 x 314162c when one pulley is larger than the other pulley ldd2 x 314162cdd 2 4c belt
