The primary impact crusher offers high capacity and is designed to accept large feed sizes. The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71") in the largest model. Primary impact crushers are generally used in nonabrasive applications and where the production of fines is not a problem.
The particles produced are then further fragmentated inside the crusher as they collide against crusher chamber and each other, producing a finer, better-shaped product. Vertical shaft impact crushers, on the other hand, are used in the last stage of the crushing process, especially when its required that the end product has a precise cubical ...
Gyratory crusher is generally used as a primary crusher. The crusher is popular due to its high throughput capacity and the large sized opening. The crusher is well suited for handling direct feed from haul/dump trucks. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength.
In addition to the fixed cone crushers, many cone crusher models are also available as mobile versions. This type of cone crusher can be combined with the jaw crusher, vibrating screen, and other equipment to form a mobile crushing station. The crushing station has two types: crawler type and tire type. Learn more about the Mobile …
