While on the subject, it will be worthwhile to discuss a little about the available methods/codes for the belt conveyor tension and power calculations. The basis of the belt conveyor tension and power analysis is firmly footed on fundamental physics, but still different codes and methods do differ mainly in computation of frictional resistances ...
DUNLOP-ENERKA Belt Testing Rig. 11. 2.1 Belt Conveyor An installation consists of a drive system, a take-up system, additional com- ponents and the principal item, the conveyor belt. In addition to the conven- tional conveyor there are other conveyor system developments in which the belt is the conveying element.

The tension due to the primary tension (FH) occurs of 4273.04 N. CEMA 5th methods, Fig 3 shows the results of the tension calculations that occur using the CEMA 5th standard, where the greatest energy loss is caused by the tension lift or lower of material (Tm) with a value of 14078.98 N. Tx, Tyc, Tyr, and Tym are the tension caused by friction ...
4. PROPOSED STANDARD FORMAT 4.1 Power and Tension With power and tension calculations there exists the possibility for a combination of all four of the above standards by utilizing a single friction factor for the shorter belts, but eliminating the belt length factor which can easily be compensated for with the overrating factor of the motor.
Inclined Conveyors: HP=((P x B)+(P+M)x F x S)/33,000. Effective Tension. Pull needed to move belt and load horizontally: E= F x (P+M) Tight Side Tension. Total tension to move belt and load horizontally: E 2 = E+E 1. Slack Side Tension. Additional tension required to prevent slippage on drive pulley: E 1 =E x K. Operating Tension
The modulus of elasticity is calculated by dividing the stress by the strain, where . M = modulus of elasticity (ISO 9856) F = force (N) ε elast = elastic elongation at the end of the specified number of cycles (N/mm). In other words: The higher the modulus the lower the elastic elongation per unit stress.

Counterweight calculation. Hi There, I am trying to calculate the take up weight for one conveyor. As I understand, I should check two criteria's against sizing the take up. 1- Minimum tension in order to build the determined sag in belt conveyor between idlers. 2- Minimum tension required in slack side T2 of the drive in order to prevent the ...
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
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.
The following method is used to determine the tension at any point along the conveyor: 1. Calculate the length correction factor. 2. Look up the mass of moving parts in Table 10. 3. Calculate the mass of the load from the design capacity and the belt speed. 4. Calculate the maximum effective tension under constant speed operation.
HP E = Empty Horsepower Requirement Wc = Weight per foot of Chain and Flight (Lb/ft) L = Length of the Conveyor (ft) S = Speed of the Chain (ft/min) Fc = Friction Factor of the Flights on the Bottom Housing. Note: Frictional factor used in the above formula vary depending on the specific applications and products being conveyed. Testing may be required to determine the exact values to be used.
Idlers are used on a belt conveyor to support the belt on the carrying and return strands.
