Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …
Jaw crushers are sometimes also referred to as "rock breakers," which speaks to their brute force. They are almost exclusively used as primary crushers because they excel at breaking up some of the largest and hardest materials into more manageable pieces for further reduction by different crushing equipment. Jaw cr…
Cone crushers and jaw crushers both work by compression, reducing materials by squeezing them until they break apart. The benefit …
A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer's data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.
For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw …
