For primary crushing with a reduction ratio of 6 to 1. When a relatively coarse product is desired, top size usually larger than 38 mm (1 1/2") Closed Circuit Crushing System To control top size from a single crusher operating in an open circuit, material must remain in the crushing chamber until the material is reduced to top size.
Jaw crushers are a popular alternative to primary gyratory crushers, since they can process large amounts of hard material efficiently. For 45 years, Fruitful C Series jaw crushers have proven their reliability in different primary crushing operations in aggregates, mining and recycling applications, with up to 11,000 jaw crusher installations.
