# Methods of belt conveyor calculations by cema

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
