the 5th, 6th, and 7th editions of the conveyor equipment manufacturers’ association belt conveyor design manual includes several methods to calculate the belt tension required to move bulk materials on a conveyor belt. they are beyond the scope of this short video. these methods include “historical”, “basic”, and “universal” methods.
typical conveyor capacity. 1 in = 25.4 mm. 1 ft3/h = 0.028 m3/h. 1 ft/min = 5.08 x 10-3 m/s. the product cross sectional area is defined by the idler trough shape and the product pile on top of the idler trough the trapezoid shape. this section on top of the trapezoid can be described with a circle and the angle this circle makes with the belt
5 conveyor pulley selection guide pulley/core diameter – the outside diameter of the cylindrical body of a conveyor pulley, without coating. finish diameter – the outside diameter of a coated pulley (core diameter + 2 times the coating/wrap thickness). face width – the length of a pulley’s cylindrical body.this area is intended to act as the contact surface for the conveyor belt.
for example: to find the correct number of plies for a conveyor belt 36 in. wide and 300 ft. long, with 20 ft. difference in elevation; handling sand and gravel. follow the line from the 36-in. width downward until it intersects the 500 length factor line; then follow to the right until the sand and gravel line is intersected; then down to the ply scale, where the ply will be found to be 7.

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: l=(d+d)/2 x 3.1416+2c when one pulley is larger than the other pulley: l=(d+d)/2 x 3.1416+2c+(d-d) 2 /4c. belt
this article will discuss the methodology for the calculations of belt conveyor design parameters with one practical example of the calculations and selection criteria for a belt conveyor system. calculations include conveyor capacity, belt speed, conveyor height and length, mass of idlers and idler spacing, belt tension, load due to belt, inclination angle of the conveyor, coefficient of
