3. belt conveyors - basic calculations: 1. mass of the load per unit length: load per unit length. given the production capacity qt = tph, the weight of the load per unit length (kg/m) – (lbs per ft) is calculated by: wm = 2000. qt or wm = 33 = (lb/ft) 60 x v v.
89 belt tension calculations w b =weight of belt in pounds per foot of belt length. when the exact weight of the belt is not known, use average estimated belt weight (see table 6-1) w m =weight of material, lbs per foot of belt length: three multiplying factors, k t , k x , and k y , are used in calculations of three of the components of the effective belt tension, t.
A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. the actual screw conveyor speed is calculated by dividing the selection capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm. 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and .
