95% Loaded Conveyors

Conveyor loadings may sometime exceed the recommended % of Loading, listed in the materials table. Considerations as to the material characteristics may justify up to 95% loading of tubular or shrouded conveyors. The following table lists maximum speeds limited with regard to the percentage of loading normally recommended for the specific listed materials.
