belt conveyors for bulk materials practical calculations,short belt conveyors require relatively more power to overcome the resistance to friction than long ones 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.belt conveyors calculations,belt conveyors calculations piotr kulinowski, ph. d. eng. piotr kasza, ph. d. eng. - [email protected] ( 12617 30 92 b-2 ground-floor room 6 consultations: mondays 11.00 - 12.00 conveyors www.kmg.agh.edu.pl.belt capacity chart - supplier & distributor of conveyor,belt capacity chart the following conveyor belt capacity charts show tons per hour (tph) based on material weighing 100 lbs. per cubic foot, 20° material surcharge angle with three equal length rolls on troughing idlers. capacity (tph) = .03 x belt speed (fpm) x material weight (lb. per cu. ft.).calculation methods – conveyor belts,conveyor and power transmission belts made of modern synthetics worldwide leaders in technology, quality and service further information on machine design can be found in our brochure no. 305 “recommendations for machine design”. the formulae, figures and recommenda-tions in this brochure are state of the art and a result of our years of experience. the calculation results can however differ.

step 1 estimation of surcharge angle. (typically low angle of repose will result in a lower surcharge angle and vice versa.) angle of repose.
conveyor capacity is determined by the belt speed, width and the angle of the belt - and can be expressed as. q = ρ a v (1) where . q = conveyor capacity (kg/s, lb/s) ρ = density of transported material (kg/m 3, lb/ft 3) a = cross-sectional area of the bulk solid on the belt (m 2, ft 2)
maximum belt pull f 1 factor c 1 (applies to the drive drums) factor c 2 checking the transilon type selected c 2 indicates the max. permitted belt pull per unit width for the belt type: c 2 = ε max. k 1% you can find details on the maximum elongations in the product data sheets. if these are not available, the following can be assumed (but not guaranteed): nf
these capacity factors, taken from the preceding charts are: cut and folded flights 30% loading = 3.75 short pitch flights (2/3 pitch) = 1.50. with capacity factors included, capacity will now be calculated: sc = 3.75 * 1.50 * 323 sc = 1817cu.ft. this selection capacity value will be used in the capacity table, for calculating correct size and speed.
the troughability of a conveyor belt can be estimated by using this equation, where . m'g = belt mass in kg/m². b = belt width in m. sz = carcass thickness in mm. cq = transverse rigidity factor (polyamide = 18, steel cord = 42) test

generally,all components of a conveyor should be checked at once. check the condition of the chain/belt regularly,and replace links/modules which are damaged. important in this matter is to try to find the cause of the damaged links/modules.wear patterns or damage on a chain or belt can often lead to a problem area elsewhere in the conveyor.
