Jaw Crushers are not a shaping crusher. Because they typically produce an elongated, flat and slabby product, Jaw Crushers are usually followed by a secondary crusher, such as a cone, impactor or roll crusher, for refining and further size reduction.. These crushers come in a range of styles and sizes and are capable of handling low …

Jaw crushers are mainly used in operations where the volumes involved do not justify a gyratory crusher. The throughput of a jaw crusher ranges between 30 and 1200 tph (Wills and Napier-Munn, 2015). Jaw crushers have been modelled previously; in 1953, Gauldie conducted a performance study of the jaw crusher, including a capacity …
