Reducing Belt Speed and/or Loading
Reducing Friction in The Belt Circuit
- If stainless steel snub rolls, grooved end rolls, and tracking rolls must be used due to process requirements, all rolls should be made as large as possible and be able to rotate freely to reduce friction in the belt circuit. Large diameter sprockets pull the belt more evenly with smoother hinging action, reducing rubbing of the belt mesh at its hinge points and the sprocket teeth, thus …
Improve Natural Lubrication of Conveyor Components
- When the processes are dry, such as conveying frozen or baked products, and natural lubrication of the conveyor components from the product or process is minimal, Wire Belt Company recommends plastic drive sprockets, end rolls, and belt support strips. Both Delrin® (or equivalent), or UHMW polyethylene plastics provide smooth and relatively strong alternatives to …
Creating Awareness of Rinsing Requirements
- Sanitation crews should be made aware that all belts, sprockets, end rolls, nose bars and support strips must be thoroughly rinsed of all product residue and cleaning products.
Continuous Cleaning Systems
- Many conveyor systems use clean-in-place, wash and brush systems to continuously keep the belt free of any type of product or residue build-up on the belt.
Correct Belt Selection
- Flat-Flex belts are available in a variety of mesh sizes and wire diameters. Selection of the correct mesh and wire size is important with respect to the application’s belt speed, length of the conveyor, size, weight and distribution of the load. Always select the largest mesh size and wire diameter available consistent with the application. Wire Belt Company’s Technical Sales depart…
