  • Osborn Double Roll Crushers can be used for primary and secondary crushing. The Double Roll Crusher is generally regarded as a 4:1 feed to product ratio crusher; however in some instances, dependent upon material friability and hardness, it is possible to achieve a 6:1 crushing ratio.

    The feed material should enter the centre of the gap between the two rolls and spread across the full roll width for maximum efficiency and this ensures a uniform product size distribution.

    Double toggle jaw crushers are heavy duty designs primarily utilized to crush the hardest of ores and ferro materials. Although extremely rugged,...

  • Jaw crushers process medium to hard quarry rock or other materials by compressing it between the fixed jaw and the swing jaw. The swing jaw being the moving part is attached to a rotating eccentric shaft. The fixed jaw is an integral part of the crusher frame. Both jaws are fitted with manganese jaw liners that can be replaced or reversed when worn.

    During the crushing operation, the toggle plate which acts as a pivot point for the jawstock, controls movement of the lower part of the...
