Compare this capacity with that at belt speeds of 150 250 and 350 fpm and m min . Choose the type of conveyor and elevator to handle this material under the conditions given. Calculation Procedure 1. Find the maximum allowable product weight at the given belt speed Use the relation P KC 60 S where P maximum product weight on the belt at any one time lb kg between belt supports K load lb h kg h C center-to-center distance between belt supports ft m S belt speed ft min m min . Substituting we have P 100 000 32 50 60 lb kg . 2. Determine the maximum allowable product weight at other belt speeds Typical conveyor belt speeds vary from a low of 150 ft min m min to a high 800 ft min m min depending on belt width type of material conveyed belt construction etc. For this belt using the data given earlier P 100 000 32 150 60 lb kg when the speed is 150 ft min m min . Likewise for the two higher speeds respectively P 100 000 32 250 60 lb kg P 100 000 32 350 60 lb kg . 3. Verify the type of conveyor and elevator to use With such a wide variety of conveyors and elevators to choose from it is wise to verify the choice before a final decision is made.
