Assuming a uniform feed to the conveyor, the cross-sectional area of the load on the conveyor belt is the determinant of the belt conveyor capacity. CEMA Recommendation 1. Select the belt width and speed based on a capacity design factor of 80% the theoretical maximum tons per hour (reduction of capacity).

How To Calculate Conveyor Belt Tensions Rulmeca Corp

The three values CEMA provides are 3%, 2%, and 1.5% sag Those percentages are based on material lump size, the proportion of lumps vs. fines, and the idler troughing angle. Note that T 0, the minimum tension to prevent sag, may be reduced if the belt is less than fully loaded. The three pertinent equations are: T0 = 4.20 Si (Wb + Wm) for 3% sag

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 0.08 for dual drive systems with rubber-lagged drive pulleys, an automatic take-up, and 420° of wrap angle, or as large as 1.2 for a single drive system

For a given speed, belt conveyor capacities increase as the belt width increases. 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.
