Marcy Double Roll Crushers are useful for intermediate size reduction of hard to medium hard materials such as rock or ore in preparation for finer reduction in a pulverizer after processing in a jaw crusher. They also bridge the gap between laboratory, and continuous production or pilot plant crushing capacities. Topsize is approximately 13mm and final fineness typically passes a No.10 (2mm) opening, depending on material type. Output size is controlled by adjusting the gap between the rollers using a hand lever. Feed hoppers open easily for cleaning and maintenance access, and feature an electrical safety interlock that shuts power to the unit when the hopper is lifted.
