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 61) 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
capacity of the belt acting as a trough. In the past the inclination of the side rollers of a troughing set has been 20° . Today the improvements in the structure and materials in the manufacture of conveyor belts allows the use of troughing sets with side rollers inclined at 30° / 35°. It may be observed however that the belt width must

· 35A 1400 mm width inclined belt conveyor has its head pulley at the elevation of 22 meter from ground, is used to convey 45 TPH coal. The head pulley is coupled to motor of RPM 1450 through planetary gear box of efficiency 80%. Then calculate the motor rated power to drive the conveyor. Consider motor efficiency 90%.

Having been confronted with conveyor design standards for a number of years, I have still to find a true specialist need, I know that some clients require less capacity on a belt, others require larger pulleys and thicker belts, requiring the use of complied formula to arrive at a solution, but this can not be justifiion for devising completely individual specifiions, which could more ...

A belt conveyor is a conveyor in which the product rides directly on the belt. The belt is supported by either a roller bed conveyor section or a slider bed conveyor section. This manual will explain the various types of Mathews' belt conveyors. This manual describes the following types of belt conveyors: 1. Horizontal Belt Conveyors 2.

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 area is intended to act as the contact surface for the conveyor belt.
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 longdistance conveyors, dynamic startup calculations. may be required, because not all elements are set in motion simultaneously,
a stronger belt type (with a higher k 1% value) must be used. C 2 indies the max. permitted belt pull per unit width for the belt type: C 2 = ε max. k 1% ≤ C 2 [] b n mm Factor C 3 (applies to the drive drums) Mechanical capacity calculated on the drive drum P A Mechanical capacity required P M P a P M = [kW] = the next largest, standard ...
Figure 1 shows an example of combinations of belt speed and belt width to achieve Specific conveyor capacities. In this example it is assumed that the bulk density is 850 kg/m3 (coal) and that the trough angle and the surcharge angle are 35' and 20' respectively. Figure 1: Belt width versus belt speed for different capacities.
· 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 36in. 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.
Belt width is a function of the largest lump size (largest product particle size), operating speed, and the desired belt capacity (SME, 2011). The largest belt belt width of all conveyor .
· Chevron conveyor belts are used to carry wet, loose and ne materials such as coal, minerals, metal ore, aggregates, concrete, grain, slurry and waste products on steep inclines. The raised ribs of the chevron belt prevent the material from running back and increase the capacity of material that can be conveyed at steep angles between 18˚ and ...
CONVEYOR BELTS TECHNICAL DATA – NN BELTS. contd. Notes 1. MRF MUSCLEFLEX belts are designed to denote the full thickness breaking strength in kilo Newtons / metre width and the number of plies comprising the carcass. For example a rating of 315/3 .
