Capacities and performance characteristics of jaw crushers

Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of the proper machine difficult. Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw crusher.

throughput | Overhead Eccentric Jaw Crushers
