Secondary Crushing Equipment For Sale
With the development of the crushing and mining industry, crushing equipment plays important role in the whole process. In the crushing process, it can be divided into primary crushing and secondary crushing. Jaw crusher is mainly used in the first crushing process. The secondary crushing equipment often involves cone crusher and impact crusher.
Secondary crushing equipment
Impact crusher and cone crusher are the main machines in the secondary crushing equipment.
Impact crusher works using the energy contained in falling stone, plus the power imparted by the massive impellers. Rock fed into the breaker falls directly on to the impellers and rotates away from each other, turning up and outward, at speeds from 250 to 1000 rpm depending on the desired size of finished product. Pieces of rock are sent crashing against steel breaker bars mounted in specific positions around the breaking chamber or crash against other rocks hurtling through the chamber and are further reduced without the use of extra horsepower. The stone falls again onto the impellers to repeat the cycle until reduction is complete. Size is controlled by impeller speeds and the vertical and horizontal spacing of adjustable breaker bars.
In cone crusher the stress to the feed is applied between a stationary and a movable surface. The crushing head is employed in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place around the cone.
