Profile: Duromech specializes in providing jaw crushers, vibrating screens, feeders, cone crushers, and vertical shaft impact crushers. Our jaw crushers are often used for primary and secondary crushing. These compressive crushers are suitable for most any type of materials. In this type of crusher, reduction takes place between a stationary jaw plate and a moving jaw plate. The moving jaw plate is mounted on the lever/pitman, which is given a reciprocating motion.
