Belt Conveyor Capacity Table 1 Determine the surcharge angle of the material The surcharge angle, on the average, will be 5 degrees to 15 degrees less than the angle of repose ex 27 176 - 12 176 = 15 176 2 Determine the density of the material in pounds per cubic foot lb/ft3 3 Choose the idler shape 4 Select a suitable conveyor belt ....

analysis and calculations than can be included in this manual Although the programs are treated as proprietary information, each CEMA member company welcomes an opportunity to assist in the proper application of belt conveyor equipment One advantage of using computer programs is the speed and accuracy with which they...

For a given speed, belt conveyor capacities increase as the belt width increas Also, the capacity of a belt conveyor depends on the surcharge angle and on the inclination of the side rolls of three-roll troughing idlers The nominal cross section of the material on a belt is measured in a plane normal to the belt...

Manufacturers Assocation CEMA recom-mends that wing pulleys not be used on belts traveling over 2,25 meters per second 450 ft/min A better choice than the conventional winged tail pulley is a spiral-wrapped tail pulley Figure 65 These pulleys have an additional steel strip wrapped in a spiral around the pulley circumference The steel...

The historical method that CEMA provides to calculate T2 slip is as follows T2 slip = Te x Cw, where Cw is the CEMA wrap factor for a rubber surfaced belt The wrap factor can be as small as 008 for dual drive systems with rubber-lagged drive pulleys, an automatic take-up, and 420 176 of wrap angle, or as large as 12 for a single drive system ....
