BELT CONVEYORS FOR BULK MATERIALS 1. INTRODUCTION: Belt conveyors consist of two powered pulleys with a continuous loop of belting material used to convey products. Belt conveyors are the most economical powered conveyor and are typically used for conveying products over long distances, at high speeds, or for incline/decline applications.
Calculation Of Counter Weight In Belt Conveyor Pdf Feb. Belt conveyor counter weight calculation scribd counter weight calculation the following steps can be taken to calculate the required take up weight for a conveyor calculate total resistance for the conveyor, this includes the lift of material, acceleration, skirt friction, idler friction, belt get price

side. This prevents excessive belt sag from the belt’s own weight. In standard conveyors for light materials handling, the conveyor belt runs over two end drums (in this case end and drive drums). The best configuration, called a head drive, is where the drive drum is at the end of the conveyor where the pro-ducts are discharged. In this case
WB = Weight of Belt (lbs/ft 2) B = Belt Width (feet) WL = Weight of Load on Belt (lbs/ft 2) L = Conveyor Length (ft.) (c/l of drive shaft to c/l of tail shaft) 2. Calculate the drive tension per foot of belt width by dividing Td by the belt width (B). 3. If using the belt at an elevated temperature, multiply the maximum allowable tension per foot
the inspection and testing of belt-conveyor scale systems. Consider the diagram of a simple conveyor belt in Figure 1 below. As one would likely expect, an appropriate amount of friction must be maintained between the conveyor belt and the drive pulley to transfer the motion from the drive pulley to the belt.
conveyor belt. If the conveyor belt is under-supported on its return side, the weight of the belt in that section is supported by the pulleys as a catenary load, and greater belt tension is needed to prevent excessive sagging. Belt return support rollers should be spaced so that the belt does not sag excessively between each roller.
WB = Belt weight (lbs/ft) use actual or estimate from Table 5-5 WM = Material weight (lbs/ft) = (Q x 2000) / (60 x Vee) Q = Quantity of material conveyed (tons per hour) Vee = Design belt speed (fpm) SI = Spacing of idlers (ft) Kl = Lump adjustment factor (see Table 5-6)

In the case of perforated belts please note: calculate the load-bearing belt width b 0 based on the number of per-forations which decrease cross sec-tions. Staggered perforations in partic-ular can reduce the load-bearing belt width considerably. Reduce the figure for the load-bearing belt width b 0 by a further 20 % to take tolerances for per-
89 Belt Tension Calculations W b =weight of belt in pounds per foot of belt length. When the exact weight of the belt is not known, use average estimated belt weight (see Table 6-1) W m =weight of material, lbs per foot of belt length: Three multiplying factors, K t , K x , and K y , are used in calculations of three of the components of the effective belt tension, T

As one would likely expect, an appropriate amount of friction must be maintained between the conveyor belt and the drive pulley to transfer the motion from the drive pulley to the belt.
6.2.2 Counter Weight 1. Stop the conveyor belt, when it is empty. Never stop the belt in load. 2. Do the positive isolation of all the electrical power sources of conveyor system. 3. Spillage material accumulated on counter weight should be removed on regular interval. 4. A counterweight and its pulleys suspended above the floor
Counterweight Formula REACH BACKSPAN COUNTERWEIGHTS Note: All rigging devices must be securely tied back. Counterweights = (4) x (Rated hoist capacity) x (Reach) (Backspan) Labels on all Spider devices requiring counterweights provide actual number of 50 lb. (22.7 kg) weights needed or total counterweight required for each reach. No guesses. No

If, for example, T2 = 1,000 lbs, in the case of a counterweighted take up, the weight of the counterweight must be 2,000 lbs. That is because the 2,000 lbs provided by gravity will be resisted with an equal and opposite force of 1,000 lbs in each of the two strands of conveyor belt.
that our belt widths do not always coincide with those used internationally. From the SABS Standard Specification for Steel-cord- reinforced conveyor belting we are able to determine the preferred belt widths used in the South African market. Using these as a basis and tabulating the various face widths we arrive at the following table (Table 3).
