8.2.1.1. Jaw crushers. Jaw crushers were invented in 19 th century and are mainly used as primary crushers to produce material that can be transported by belt conveyors to the next crushing stages. The crushing process takes place between a fixed and a moving jaw. Shaft rotation, along with the toggle plate, causes a compressive …
Iron ore primary crusher. Jaw crushers are generally used for head crushing in iron ore production operations, and gyratory crushers are used in large production units (especially large foreign mines). Jaw crusher is the most traditional and most stable and reliable primary crushing equipment, and has the widest application range.
The primary can produce these sizes at a rate of 150 to 12 000 mtph depending on the feed characteristics of the ore, the crusher setting, crusher size and the connected …
5.1 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 x 1880 mm with a cone angle of 18°.
13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.
The steam shovel began to change the entire picture of open-pit working.With the steam shovel came the really ''huge" No. 8 crusher, with its 18″ receiving opening. Up to this time the jaw crusher had kept pace with the gyratory, both from the standpoint of receiving opening and capacity, but now the gyratory stepped into the …
The majority of gyratory crushers are used as primaries, i.e. they receive the initial feed from the mine or quarry. The same type of crusher with chamber modifications is used as a secondary crusher, particularly when following a large primary crusher. The fine-reduction gyratory crusher can also be used for tertiary crushing.

The processed ore size defines the type and position of each stage. For instance, the primary crushing stage receives the extracted iron ore directly from the mine, where the iron ore diameter may reach 1 m. In the quaternary crushing stage, the size of the ore that feeds the crushers is less than 20 mm. Screens classify the ore by size and ...
