A simple conveyor belt system consists of two pulleys of equal diameters and a belt which runs across them. Now we will consider an ideal case where there is no slipping of the belt on the pulleys. ( When the belt moves forward without taking the belt with it is known as slip of a belt.
Conveyor Application Formulas Today many of these formulas are incorporated in available software that allows for the immediate analysis and generates a complete list of components either for a new conveyor or for problem resolution on existing conveyor systems.
The service life of a conveyor running at a higher speed may be shortened considerably. Most conveyors are not designed to run over 200 FPM. When they do, some parts may need to be balanced to prevent excessive vibration, and special bearings may be required.

The way to accurately find the speed of a conveyor is to measure the length then time it for 1 or several rotations. Make a mark "Start" on the belt, measure with a long tape measure to a second point, advance the conveyor then measure from point 2 to a new point 3, …
More information required. What is the nameplate speed of the motor, and the diameter of the driving drum. If you calculate the RPM of the driven sprocket, and you know the diameter of the driven drum, then you can calculate the surface speed of the conveyor.
Belt Gearing. The relationship between the rotational speed of the motor and the fan and the disc diameter can be expressed as. d f n f = d m n m (3). Horsepower. If belt tension and belt velocity are known - horsepower transferred can be calculated as
A handy online tool for the knifemaker to determine the speed of a belt based on motor, power frequency and a combination of sheaves.
screw conveyor capacity & speed calculation: Visit the online engineering guide for assistance with using this calculator. Click on symbol for more information.
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, due to the elastic properties of the conveyor belt.
Note: For long-distance conveyors, dynamic start-up calculations may be required, because not all elements are set in motion simultaneously, due to the elastic properties of the conveyor belt.
With that input, the controller can monitor any speed differential between the primary conveyor belt and the secondary conveyor belt. Any time that difference exceeds tolerance, the controller can command the drive to speed up the motor until the speed of the primary belt matches that of the secondary belt.

Belt speed (V) – 1.2 m/s Troughing angle (λ) – 35 0 Conveyor Inclination – 10.36 0 Take Up Travel – 600 mm Type of Take up – SCREW 5. DESIGN OF BELT CONVEYOR The design of the belt conveyor must begin with an evaluation of the characteristics of the conveyed material and in particular the angle of repose and the angle of surcharge.
The calculations are based on the average safe strength (factor of safety, 15) of the various standard rubber conveyor belts. The calculations assume maximum loading conditions; that is, the belt is considered as carrying the greatest load that it will handle without spillage at ordinary belt speeds.

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 friction, power at the drive pulley, starting belt tension, acceleration of the conveyor belt, and belt breaking strength, all with descriptions of …
If you know any 3 values (Pulley sizes or RPM) and need to calculate the 4th, enter the 3 known values and hit Calculate to find the missing value. For example, if your small pulley is 6" diameter, and spins at 1000 RPM, and you need to find the second pulley size to spin it at 500 RPM, Enter Pulley1 Size 6, Pulley 1 RPM 1000, Pulley 2 RPM 500, and hit Calculate to find the second pulley diameter.
Done this way you can use this formula to solve for a multi pulley drive. Just remember that idlers do not change the output of the drive system. They are used to provide tension or to route the belt. Below is the basic formula, an example, and a Pulley Speed Calculator for your use.
