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° - 12° = 15°) 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 speed. 5. Convert the desired tonnage per hour (tph) to be conveyedScrew Conveyors for DISTRIBUTION,Scre Conveyors for Bu Materias ANSI/CEMA Standard 350. 144. The derivation of the basic formula for the horsepower of horizontal screw conveyors is as follows: C = 3Capacity, (ft/hr) 3W = Apparent density, (lbs/ft) L = Length of conveyor, (ft) F. m.Belt Conveyors for Bulk Materials - Fifth Edition - Chapter 6,the belt and the idler rolls can be calculated by using the multiplying factor K x . K x is a force in lbs/ft of conveyor length to rotate the idler rolls, carrying and return, and to cover the sliding resistance of the belt on the idler rolls. The K x value required to rotate the idlers is calculated using equation (3).

### Belt Conveyors for Bulk Materials Practical Calculations

and therefore an adjustment is made to calculate the effective tension. L C = L + 70 m (metric) L C = L + 230 ft (imperial) Therefore, the belt length correction is: C = L c L All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping.CEMA Screw Conveyor Engineering Standard 351-2007,1. Perform screw feeder speed calculations for normal operating conditions to determine operating speed at the desired capacity, lowest density, degree of incline and screw pitch. Set the trough loading to 95-percent. Be sure to use the speed calculated for the appropriate housing style if the screw feeder is inclined. 2. Perform screw feeder horsepower calculations for worst-case operating conditions usingCEMA Belt Book First Printing - Home - Conveyor Equipment,,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). This allows for surge loading and reduces spillage due to,
