Factors to Consider When Selecting the Proper Roll Crusher …
— A good rule of thumb for single-stage crushers is that a Single Roll Crusher provides up to a 6:1 ratio of reduction and a Double Roll Crusher provides up to a 4:1 ratio of reduction. In the event that the application requirement exceeds the guidelines discussed herein, dictating more than one crushing stage, then a determination will have to ...
Crushing in Mineral Processing
— Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.
Selecting the right crusher for your operations
— Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can …

Jaw Crushers
The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size. For Retsch jaw crushers, this lies between 26 and 220. A high value reflects the capacity of a jaw crusher to accept large sample pieces and provide powerful crushing performance, resulting in high final fineness.
Jaw Crusher BB 300
The Jaw Crusher BB 300 is specifically designed for accepting large feed sizes up to 130 mm. The gap width can be set stepless from 1-40 mm. Depending on the sample material, particle sizes down to 5 mm can be obtained, resulting in a crushing ratio of 26. A throughput of up to 600 kg/h is possible with the BB 300.
