American Standard without Rollers ANSI BS29-12

The smooth and stable flow of material through a process depends on the performance of the conveyor chain installed within the equipment. Bush class chains or steel knuckle chains (JKB) are of the same construction as roller conveyor chains (JKR), but with the roller excluded. This series, with a reduced number of components, has proved to be particularly successful in high duty, high abrasion applications where lubrication is not possible. For many years KING steel bush chains have been proving performance in hotstone elevators.

Our own preference is for single strand high duty centrifugal discharge elevators. Experience has seen improved performance with a central chain system. Twin strand, although commonplace, does demand extra considerations on material infeed position, equilibrium in chain loading and strand matching accuracy.
