When installing a conveyor belt scale on a conveyor with a curve, the scale should be installed at a location where the curve does not influence the scale performance curves can be concave or convex as shown in fig 6 if the con-veyor has a concave curve, the curve will have a lifting effect on the belt in the area of the curve if this lifting.Get Price List

Conveyor belt concave in ethiopia.Concave conveyors will head your list of problem conveyors this is due to the fact that the conveyor belt will lift off the troughing idlers and return rolls as indicated by the dotted lines there will be long distances of no roller contact ad lack of tra.
Belt conveyors for bulk materials fifth edition ch.Exact calculation should be made the following formulae all involve point c, the start of the concave curve but, for the rst approximation, point c will be used to prevent the belt from lifting off the idlers with the belt conveyor running, the formula is 1 where r 1 minimum radius, ft, to prevent belt from lifting off the idlers t c.
A conveyor belt module has a conveying surface and a shaped bottom surface.The shaped bottom surface includes a concave lateral channel in the shape of a bell curve, designed to accommodate a nosebar, so that a conveyor belt formed of the modules can smoothly navigate the nosebar.The module includes hinge elements having elongated, slotted openings that are offset from the vertical center of.
Usually, conveyor belts are resistant to up to -30c.Lower temperatures may be achieved with special compounds.Constant movement of the belt may be required.Concave curve.The concave radius of a conveyor must be sufficiently large to avoid belt lifting from the conveyor.Compression set.

Common belt conveyor proles and tensions.For simplication, the text and diagrams in this chapter are principally con-cerned with vertical curves on the carrying run of the belt conveyor.Concave vertical curves a conveyor belt is said to pass through a concave vertical curve when the center of curvature lies above the belt.See figure 9.1.
Concave and convex vertical curves have a belt tube inside lower half belt tension fall - too low a tension will make the belt go into compression and cause tube and belt buckling the required minimum concave curve radius for belt lift off for item no.3 above is calculated as it is for troughed conveyors and is shown in the vertical curves.
A concave curve beyond the scale shall start no closer than 12m 40 ft from the scale.If installed on a conveyor with a concave curve, the scale must be installed in a section of the conveyor where the belt is straight not necessarily horizontal and in contact with at least 8 idlers to either side of the scale throughout the entire loading.
When installing a conveyor belt scale on a conveyor with a curve, the scale should be installed at a location where the curve does not influence the scale performance.Curves can be concave or convex as shown in fig.6.If the con-veyor has a concave curve, the curve will have a lifting effect on the belt in the area of the curve.If this lifting.
Belt running off the idlers is not an issue for closed belt conveyor systems since either the total belt or the belts axial profiles are locked up in the idlers.Figure 17 typical radii of horizontal curves for different belt conveyors figure 17 shows typical horizontal curve.
L.Concave and convex curves see figures 11 11a if the conveyor is designed with a concave curve figure 11, the belt scale must be located 40 ft.From the point of tangency as curves induce inherent mis-alignment.Concave curves require special attention, since the belt tends to.

A long belt conveyor, often called as overland conveyor, may follow a complex conveying path and may include horizontal and vertical curves.Belt tensions at different points are not needed in case of a small in-plant belt conveyor but in case of overland conveyors due to the addition of the horizontal and vertical.
Belt conveyor systems fig.4 belt conveyor system with nominal load these high belt tension forces result because power is fed at places where it is not required and has to be transferred by the belt over a long distance.In order to find optimum power distribution here, it must be known where the belt is loaded.
