Hadfield jaw crushers are used in certain mines to break oversize rocks before going into the mill.
Previously phosphor bronze was used for the two 200 mm (8") outside diameter x 170 mm (6.7") inside diameter
bushes, each of which was 270 mm (10.6") long.
Due to a lack of regular lubrication, the bronze bushes tended to wear out quickly. The bronze bushes were
replaced with Vesconite. After 12 months of operation the crusher was overhauled and the Vesconite bushes showed
very little wear.
Vesconite survives the irregular lubrication and the dirt and dust which characterise crusher operation, giving
longer wear life and reducing costs.
