designers of conventional conveyors familiar with the CEMA method of conveyor belt calculation a method to modify the CEMA equations so they can be used for pipe conveyor preliminary design. The methods outlined in this paper are not meant to influence the pipe/tube conveyor manufacturer =s design and standards but to provide a
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.
Pipe belt conveyor is a new type of special belt conveyor and it is wildly used in conveying powder material. Calculation of pipe belt conveyor¿s main parameters is different from that of
In the case of perforated belts please note calculate the loadbearing belt width b 0 based on the number of perforations which decrease cross sections. Staggered perforations in particular can reduce the loadbearing belt width considerably. Reduce the figure for the loadbearing belt width b 0 by a further 20 to take tolerances for per
Based on points 16. above you need to determine the pressure distribution under and adjacent to each and every steel cord across the belt influenced by product loading belt forming forces (transverse stiffnes) horizontal and vertical pressures and belt bending forces.
The belt tension at steady state can be calculated as Tb = f L g 2 mi (2 mm) cos (δ) (H g mm) mi = Load due to the idlers in Kg/m. = Load due to belt in Kg/m. mm = Load due to the conveyed materials in Kg/m. δ = Inclination angle of the conveyor in Degree. H = vertical height of the conveyor in meters.
Pipe Conveyor Power Calculations. But pipe conveyors are more belt sensitive due to effects of transverse belt stiffness (Figure 1). Figure 1 Although transverse belt stiffness is important to the belt manufacturer of a conventional conveyor in that the belt must be stiff enough to support the load and flexible enough to sit properly in the trough it is not a consideration the conveyor .
Step 3 Estimation of Surcharge Angle. (Typically low angle of repose will result in a lower surcharge angle and vice versa.) (Highly cohesive matrls fine moist or interlocking use 5 10deg.) (Do not delete) (Do not delete) Vibrating Feeder Belt Feeder Apron Feeder to (varies with bed depth to width ratio) Bucket wheel
The Pipe Conveyor can negotiate much tighter curves than a flat belt as well as it can negotiate steep inclines and this will facilitate complex routing requiring less space than a conventional conveyor. This advantage of being able to run tight curves is an essential aspect since it can eliminate transfer points that are normally necessary
Pipe Conveyor Excel Calculation Specialswonen. Conveyor capacity is determined by the belt speed width and the angle of the belt and can be expressed as q = a v (1) where q = conveyor capacity (kg/s lb/s) = density of transported material (kg/m 3 lb/ft 3) a = crosssectional area of the bulk solid on the belt (m 2 ft 2) more info pipe wall thickness calculation asme b313 excel.
The belt tension at steady state can be calculated as Tb = f L g 2 mi (2 mm) cos (δ) (H g mm) Where Tb is in Newton. f = Coefficient of friction L = Conveyor length in meters. Conveyor length is approximately half of the total belt length. g = Acceleration due to gravity = m/sec2 mi = Load due to the idlers in Kg/m.

Motor and Gearbox Specifications. When carrying out belt conveyor load calculation the total payload on the belt conveyor as well as the area the load will take up on the conveyor need to be considered. Most belt conveyors are designed with the belt being dragged over a stainless steel deck. This causes friction between the belt and the deck.
Calculation of pipe belt conveyor s main parameters is different from that of conventional belt conveyor s. The parameters such as throughput belt speed belt width resistance tension in belt and power are described. The length of transition section is analyzed because it is important to the belt life.
Belt Load. At one time when the load is known per square foot P= G 1 x C (in feet)x W (in feet) At one time when load is known by pounds per hour P=G 2 / (S x 60) x C (in feet)

Pipe Conveyor Design. Pipe conveyor use and applications are becoming more popular around the world. Sidewinder allows pipe conveyors to be analyzed and incorporates many specific equations for their proper design. This includes inputs for power calculations as well as calculating belt stresses in combined vertical and horizontal curve areas.
Level Ground Conveyors Horsepower required for conveyors transporting material on level ground 1 hp (English horse power) = W = kW 1 ft (foot) = m = 12 in = yd Lifting Conveyors With lifting conveyors add lifting power from the chart below to the level ground power from the chart above.

In pipe conveyors the belt is rolled into a tube. These conveyors can negotiate tight curves and keep the material isolated from the environment. Our engineers invented a special carcass construction that is used by leading belt manufacturers to ensure the pipe is stable in horizontal curves (US Patent USB2).
L=belt length (IN) C=centertocenter distance (IN) π= D=large pulley s diameter (IN) d=small pulley diameter (IN) The math is not as difficult as it appears. Here s the logic behind the centertocenter distance formula 2C Multiplying the centertocenter distance by 2 accounts for the belt length on the top and bottom of the
