The design of a conveyor belt is not limited to merely determining the tensions only, but to the whole design of the conveyor system. That implies that the component parts of the conveyor be adequately and correctly specified, in order to perform the tasks required of them. 3.8. Preliminary Designs and the Field Mining Engineer

Incline/Decline Belt Conveyor Incline conveyors require tighter tension force, higher torque, and traction on the belt surface to prevent items from falling off the belt conveyor. Thus, they will incorporate a gear motor, a center drive, and a take up. The belt must also have a rough surface to allow for greater traction. Modular Belt Conveyor

Basically, two forces are acting on a conveyor belt scale at the same time: (1) a vertical force due to the weight of material (i.e., the load being measured); and (2) a horizontal force of the belt being pulled across the scale idler. The latter must be mechanically eliminated to provide a high accuracy reading of the material weight.

The air velocities spanned the range from 1.0 m/s to 6.9 m/s. The results of these experiments are compared to previous large-scale results obtained using a smaller fire gallery and much narrower (1.07-m) conveyor belts to determine if the fire detection criteria previously developed (1) remained valid for the wider conveyor belts.
