The rated capacity at 5" closed-side setting was 490 stph based on standard 100lbs/ft3 feed material. These crushers were fed a very fine ore over a 4″ grizzly which allowed the 1000 TPH the SAG mills needed. For crushing operations under 500 TPH, the design engineer will typically select a jaw crusher as they are of lower cost. ...
JAW CRUSHERS. Since the jaw crusher was pioneered by Eli Whitney Blake in the 2nd quarter of the 1800s, many have twisted the Patent and come up with other types of jaw crushers in hopes of crushing rocks and stones more effectively. Those 'other' types of jaw crusher inventors have given birth to 3 groups: Double Toggle of the Blake Type; Dodge Type
Additionally, gyratory crushers have a higher crushing ratio (meaning that they can crush large material into smaller pieces), a larger feed opening, and a more consistent product size and shape compared to cone crushers. However, cone crushers have a more efficient crushing action for smaller materials but can produce more fines.
Cone crushers resemble gyratory crushers from the technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. ... This can be …
Impact crushers are suitable for materials that are soft or easily cleaving from the surface. The crusher consists of a fast spinning rotor and beaters attached to the rotor. The feed is entering to the crusher from the top and crushing starts immediately when the feed is impacted with beaters towards the crusher's inner surface.
