  • Double Roll Crusher Osborn

    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
