belt moves onto the pulley the tensions must equalize quickly across the belt width and “belt creep” in the low tension areas can occur. Adequate transition distances are extremely critical with the use of today’s high modulus, low stretch, conveyor belt carcasses. The stresses resulting from a short half trough transition distance at the

When constructing a new conveyor, you should select the belt to match the transition distances. In the case of replacement belting for existing conveyors, the belt should be selected to match the existing transition distances.

Belt Transition in a Troughing Application Most bulk haulage utilizes troughing idlers to carry loads. Conveyor idlers support the belt as it conforms to the angle of the outside rolls. When the belt goes from “flat to Minimum Transition Distances, and Locations of Transition

6 Insufficient edge sealing distance. The free belt edge outside of the skirtboards in the loading zone of a conveyor is called the edge sealing distance. The CEMA standard is based on the distance between the inside dimensions of the skirtboards being equal to 2/3 the flat belt width, which does not account for the toughing angle.

Conveyor belts on installations, where the belt width is equal or larger than the conveying length, are increasingly difficult to guide. Namely thin belts with little lateral stiffness, particularly at high speed, have a tendency to buckle and potentially fold over when fitted on short conveying distances

Ensure proper transition distances. Potential Cause: Belt has been stretched or is worn out. Fix: Replace belt. Potential Cause: The top cover is too heavy for the thin-ply belt. Fix: Consult a quality belt manufacturer. Problem: Belt is hardening and/or cracking. The hardening and/or cracking of a rubber conveyor belt is a result of exposure

– The conveyor belts’ arc of contact on the drive drums is to be increased; The distance between the top and return side must be small for design or construction reasons. When using belts with a patterned sur-face, we recommend lagging the drums to reduce noise. If the arc of contact of snub rollers, sup-

conveyor belt carcasses. As you can see from the picture shown, the belt is flat over a terminal pulley and troughed at various degrees on the conveyor. The distance measured along the edge of the belt in the transition area is greater than the distance measured along the center of the belt

Feb 18, 2020· Smooth transition between different set of idlers or idlers and pulley are key for proper operation and reliability of a belt conveyor. In particular, an improper transition between the troughed belt section and terminal pulley(s) has been reported as the root cause of many problems including misalignment, and it is often necessary to adjust
