Pipe belt conveyor is a new type of environmentally friendly and efficient bulk conveying equipment. In the design of the roller, the belt and the driving motor of pipe belt conveyor, the sag resistance is a key parameter. Meanwhile, the normal force between the conveyor belt and the roller group is the other important factor need be considered and has a great influence on the sag resistance.

· Conveyor belt sag, also known as catenary sag, refers to the tensionless section of the belt that hangs down on the return side (or underside) of the conveyor. It is an intended section of the belt that is required to keep your conveyor running smoothly. The catenary sag is a natural way to tension the belt.

Belt Conveyors are also a great option to move products through elevations. Incline Belt Conveyors from low to high and Decline Belt Conveyors from high to low. This manual is short, with quick and easy reading paragraphs, very practical for calculations of belt, chain conveyors and mechanical miscellaneous, in the metric and imperial system.

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.

Next it is important to calculate T2 sag (slack side tension required to prevent belt sag.) Sag is a phenomenon which can occur at the point of minimum tension in the carrying strand of a conveyor belt. On an inclined conveyor, it is usually in the vicinity of the loading zone.

PPI''s Stretch-Rite calculations provide the opportunity to use manual (fixed) take-ups on conveyors that are longer than 150''. The Stretch-Rite analysis in the Precision Conveyor Design provides guidance on the selection of travel length and initial belt stringing conditions to achieve proper tension to prevent slip or excessive sag.

OCC has significant experience designing and evaluating pipe conveyors utilizing its proprietary power calculation methodology. We will work with qualified belt manufacturers to ensure a belt with the proper stiffness is selected for your specific project. OCC can provide an independent and expert analysis into why and how conveyor issues occur.

Belt sag can be eliminated by correctly supporting the belt. For an effective, minimum-spillage transfer point, the belt line of travel must be stabilised with proper belt support in the conveyor''s loading zone. A flat, sag-free belt line in the skirted area is essential to successfully sealing the load zone.

Therefore, the horizontal stiffness of the belt acts against the belt sag. Figure 4.2 shows the belt sag for the example turnover with and without quarter point support rolls. The belt sag is reduced from 1.1% (673 mm) sag to 0.2% (114 mm) sag at low tension. This is a very significant reduction in sag. Also, if the tensions vary in the ...
