Conveyor Capacity. Conveyor capacity is determined by the belt speed, width and the angle of the belt - and can be expressed as. Q A v (1) where. Q conveyor capacity (kg/s, lb/s) 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)
Apr 10, 2017 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.
The third way to monitor conveyor speed is to attach an encoder to an encoder measuring wheel that rides on the surface of the belt or one of the rollers if the belt itself is crowded with product. Typically, these wheels are 1 foot in circumference, which makes an easy conversion from RPM to linear speed in feet per minute.
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
Apr 09, 2015 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, and so on until eventually you come back to start. This is the length.

Hans Renold in 1880. Later the principle was applied to conveyor chain giving the same advantages of precision, heat-treated components to resist wear, high strength to weight ratio and high mechanical efficiency. Renold conveyor chain is made up of a series of inner and outer links. Each link comprises components manufactured from

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 following formulas may be helpful for quick analysis of limited applications.
the conveyor is given by the formula where qG weight of material per linear meter Iv belt load t/h v belt speed m/s qG is used in determining the tangential force Fu. 5.1.1. Maximum speeds advised Considering the factors that limit the maximum conveyor speed we may conclude When one considers the inclination of the belt
Total Shaft H.P. Calculation. TSHP FHP MHP* *Corrected if below 5 HP. Note The actual motor horsepower required to drive the loaded conveyor system is dependent on the method used to reduce the speed the motor to the required speed of the conveyor. Drive losses must be taken into consideration when selecting the motor and drive equipment.
For example, if the motor speed is 1750 rpm and the gear drive output speed is 35 rpm, the total ratio required is 50. The nominal gear drive ratio closest to the total ratio required is 40. For a 207TR, the actual ratio is 39.124. Therefore, the sheave ratio required in this case is 1.278.
If you need more accurate then you need a feedback device on the conveyor, which also needs its output scaled to the actual conveyor speed. Spend all day calculating these numbers and then you will find out that the motor does not go 1725 RPMs at 60Hz and the gear reduction is not nominal and the belt on the conveyor slips etc etc etc.
