How is the conveyor idler spacing affecting conveyor belts?

IDLER SPACING. Excessive sag between conveyor idlers can cause load shifts that abrade belts, spill materials, and in the case of steeply sloped belts, create an avalanche. Belt sag can be kept to a maximum of 2% with conveyor idler spacing at four-foot intervals along the carrying side. By increasing the tension, the idler spacing can be increased and still maintain the 2% maximum …

Superior Conveyor Idlers: Maximizing Efficiency

Idler Spacing on Curves： Special considerations are needed for idler spacing on convex and concave curves. On convex curves, idlers need to be spaced closer to prevent the belt from lifting off the idlers due to centrifugal force. Conversely, on concave curves, larger idler spacing can help prevent excessive belt edge tension and potential ...
