Troughed and flat belt conveyor capacities are detailed in Tables 4-2 through 4-5. These tables are set up for 20 degrees, 35 degrees, and 45 degrees troughing idler. shapes and for flat belts; for various degrees of surcharge angles which correspond to. the slumping characteristics of the materials to be conveyed; and for belt speeds of. 100 fpm.
The CEMA Conveyor Design Manual provides this equation to calculate effective belt tension. Te = LKt (Kx + KyWb + 0.015Wb) + Wm (LKy + H) + Tp + Tam + Tac These parameters enable the designer to calculate belt tension required to overcome: friction gravity momentum
In the case of perforated belts please note: calculate the load-bearing belt width b 0 based on the number of per-forations which decrease cross sec-tions. Staggered perforations in partic-ular can reduce the load-bearing belt width considerably. Reduce the figure for the load-bearing belt width b 0 by a further 20 % to take tolerances for per-
belt moves onto the pulley the tensions must equalize quickly across the belt width and "belt creep" in the low tension areas can occur. Adequate transition distances are extremely critical with the use of today's high modulus, low stretch, conveyor belt carcasses. The stresses resulting from a

The fluting property of materials on the flat conveyor belt is poor and the materials are scattered, as shown in Figure 2. Then a judgment can be made by calculating the ratio of material area to the background area and dividing it into three grades. Meanwhile the material is well grooved on a slotted conveyor belt and usually clusters in the ...
