The new generation mill master chains are designed for the highest duty cement and aggregate industries applications. The chain combines the proven performance of the US central strand bush chains, but incorporates a high alloy heat treated K style dismountable attachment (KD) which mounts on an extended pin retained with a heavy duty circlip. It is the bucket location that secures the KD attachment. The design allows for quick replacement in the event of damage and the potential to turn the attachment to utilise the unworn diameter of the bushing. Clearly the revolutionary double life chains have a positive impact on the cost of ownership.
Refer to John King Millmaster catalogue for our range of high capacity bucket elevators manufactured by John King in the UK since the 1950s.
