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 calculations. may be required, because not all elements are set in motion simultaneously,

Belt Conveyors are also a great option to move products through elevations. Incline Belt Conveyors from low to high and Decline Belt Conveyors from high to low. This manual is short, with quick and easy reading paragraphs, very practical for calculations of belt, chain conveyors and mechanical miscellaneous, in the metric and imperial system.

The Conveyor Production Capacity calculator computes the number of units of some commodity that can be moved by a conveyor system in some amount of time. INSTRUCTIONS: Choose units and enter the following: ( n) - Number of units per square meter on the conveyor. ( W) - Width of conveyor. ( TS) - Transfer Speed of conveyor.

Belt Capacity Chart The Following conveyor belt capacity charts show tons per hour (TPH) based on material weighing 100 lbs. per cubic foot, 20° material surcharge angle with three equal length rolls on troughing idlers. CAPACITY (TPH) = .03 x Belt Speed (FPM) x material weight (lb. per cu. ft.) x load cross section (sq. ft.)

Conveyor Capacity. Conveyor capacity is determined by the belt speed, width and the angle of the belt - and can be expressed as. Q = ρ A v (1) where. Q = conveyor capacity (kg/s, lb/s) ρ = density of transported material (kg/m3, lb/ft3) A = cross-sectional area of the bulk solid on the belt (m2, ft2) v = conveyor belt velocity (m/s, ft/s)

Calculating Conveyor Speed. The conveyor belt speed is calculated as the circumference of the drive roller times the rotations per minute (RPM) of the motor. If there is any gear reduction, don't forget to apply the ratio to the RPM before multiplying the circumference.

Determine the minimum width of your curved conveyor. If you have guardrails on your curve and the package being conveyed is too long, the package may become jammed in the curve if the curve is not wide enough. Even without guard rails, if the package is too long and overhangs the curve, it may contact items outside the curve, causing a jam.
