At one time when the load is known per square foot: P= G 1 x C(in feet)x W (in feet) At one time when load is known by pounds per hour: P=G 2 /(S x 60) x C(in feet) Horsepower. Level Conveyors: HP=(F x S x (P+M))/33,000 Inclined Conveyors: HP=((P x B)+(P+M)x F x S)/33,000. Effective Tension

Chat OnlineThe required take-up length is calculated as follows, where. SSp= take-up length (m) L = conveyor length (m) ε = belt elongation, elastic and permanent (%) As a rough guideline, use 1,5 % elongation for textile belts. and 0,2 % for steel cord belts. Note: For long-distance conveyors, dynamic start-up

Chat Online28/12/2020· (RPM) Rotation Rate of the pulley; Belt Speed (BS): The calculator computes the belt speed (BS) in meters per second. However, this can be automatically converted to other velocity units via the pull-down menu. The Math. The formula for the speed of the belt is: BS = (D •π • R)/(2π) = ½•D•RPM. where:

Chat Online3. Belt Length Correction, L c: Short belt conveyors require relatively more power to overcome the resistance to friction than long ones and therefore an adjustment is made to calculate the effective tension. L C = L + 70 m (metric) L C = L + 230 ft (imperial) Therefore, the belt length correction

Chat Online31/05/2016· The length of a belt conveyor in metres is the length from the centre of pulley parallel to belt line. Belt length is dependent on both the pulley diameters and centre distances. Capacity is the product of speed and belt cross sectional area. Generally, belt capacity B.C(kg/sec) is given as: B.C =3.6A V ρ Where: A= belt sectional area (m2); ρ = material density (kg/m3); and V= belt speed (m

Chat Online30/06/2014· The belt conveyor as a working unit opposes tor- que MM at the same rotational speed set against torque ML. At the moment of switch on, the electric motor delivers the start-up torque MA. When this happens, the belt conveyor demands the break away torque MLB. As rotation increases the motor torque declines to saddle torque MS and then increases
