The charts list the capacity for various belt widths at the different troughing angle. These have been calculated at a belt speed of 100 FPM. To make it easier to pick out the right combination, calculate the Ceq using the following formula: Equivalent Capacity (Ceq) = C *100 / FPM Conveyor speed is an important factor in conveyor design.
The CPM throughput capacity can be calculated once the average length of the cases and the speed of the metering belt are determined. Conveyor Issues and Improving Performance To maintain optimal performance of the conveyor system, engineers suggest that the CPM throughput should be within 10% of the maximum limit.

Conveyors for Bulk Handling of Seed Soybeans Abstract Six soybean-seed conveyors were evaluated for capacity and seed damage. The belt conveyor, the flight conveyor, and the nylon-brush auger did not cause significant damage to soybean seed during conveying. The capacity of the belt conveyor declined significantly at 30° angle of inclination.
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.
The belt capacity has many variables, belt material and thickness, width, speed, distance between support rollers, trough angle (between vertical Centerline of the belt and the face of the belt) determining the depth of the material on the belt, the density and clumping factors ( usually tied to moisture content) determining the amount of stack ...
BELT CONVEYORS II TRANSPORT CAPACITY • The belt speed has to be as big as possible so that width is short. •Speed depends on material properties: –Fluidity. Dust risk. –Abrasion. Belt cut risk. –Friable. Material split risk. –Size. Great impacts on the belt take place for big sizes and heavy ones, thus weakening the belt.
Mar 13, 2018· The speed at which the conveyor belt moves depends on the size of the rollers and their revolutions per minute. Measure the diameter of the rollers around which the conveyor belt is wrapped. Multiply the diameter of the roller by pi, 3.14159.
