selecting the curve radii, determining a realistic route for the conveyor, approximations of electrical loads and preliminary equipment selection. Another area of importance is the value used for idler spacing Si. Since many pipe conveyor installations have multiple curves, convex, concave and horizontal that
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 Report. For each Concave and Convex vertical curve and each Horizontal Curve in a Pipe a Conveyor, the Calculate Pipe Conveyor Curve calculation under the main form Calcs menu must be ...
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
Nov 11, 2015 The conveyor drive, etc. are chosen to suit the application situation. The minimum radius for convex curves are quite less compared to concave radius. As an example, for 1200 mm wide belt, 40 degree trough, the radius could be around 40 m for textile fabric belt and around 100 m

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.

The DSI Sandwich Belt High Angle Conveyor technology conveys materials along a series of alternating convex curves, developing radial hugging pressure through tension. The HAC remains a successful elevating system and DSI also offers our advanced version of the HAC , which we have dubbed the GPS, or Gently Pressed Sandwich.
Dec 07, 2015 CONVEX CURVES The Keystone units patented design makes it easy to construct a variety of serpentine curves. Convex curves will add gentle grace and beauty to any installation. The following information will provide a complete explanation of construction techniques for building retaining walls with convex curves.
Effectively the capacity reduction is usually less than 3. Troughing angle For standard 3 roll idlers, the most common trough angle is 35 although trough angles from 20 to 45 are not uncommon. Steeper trough angles give increased capacity but can have consequences for convex and concave curves
Figure 9.3 Recommended minimum radii for concave vertical belt conveyor curves. To insure that the belt tension is sufciently high to avoid zero tension in the belt edges at a concave curve, a check of the curve radius should be made by the use of the following formula for fabric constructions 2
