# Conveyor Formulae For Convex Curves

### Belt Conveyors For Bulk Materials Fifth Edition Chapter 6

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 belt tension, lbs, at point c (or c 1) W b weight of belt per foot, lbs 1.11 constant, based on maximum conveyor incline of 25 to horizontal See Figure 9.3.

### Formulae For Convex Curves

Dec 09, 2004 Id like to get some idea of the formulas typically used for say stockpile yard belts with convex vertical curves. My understanding is that the minimum radius is calculated to prevent overstress at belt centre, and minimum tension at the edge of the belt. The ones Ive seen are from suppliers such as Dunlop (old), Goodyear, Apex, and the CEMA formulas.

### Belt Continuous Siemens

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 Figure 3. If the conveyor has a concave curve, the curve will have a lifting effect on the belt in the area of the curve.

### Belt Scale Reference Guide

belt speed at the scale. The conveyor speed and slope should not exceed that at which material slippage occurs. Typically this is less than a 20% pitch for most materials. 2.2.5 Convex Curves. Conveyors having convex curves should be avoided or the scale should be located in a section of the conveyor not affected by the curve.

### Sidewinder Conveyor Design Software Sidewinder Conveyor

Vertical Curve Calculations. Both convex and conveyor curve radii are incorporated in the software. Belt lift off, center and edge stresses, belt buckling, and lift off distances are calculated for each concave curve and every load case. Likewise, belt stresses in convex curves and required idler spacing is also calculated.

### Overland Belt Conveyors

Jun 22, 2017 The convex vertical curve must be large enough to prevent excessive belt tension in the outer fibers, thereby overstressing the belt. It must be large enough to prevent low tension in the center of the belt, which will cause the belt to buckle and result in spillage. The curve must also be large enough to prevent excessive forces on the idlers.
