A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).
A crusher's maximum tonnes/h output is determined when the machine is at or close to full capacity during its peak performance. Failing to maintain a full load can result in improper wear and inefficient crusher operation.
were the most common choice crushers, but in recent years impact crushers are more widely used. These crushers also are sometimes used as primary crushers for fine-grained gravel deposits. The cone crusher (a compression type) simply crushes the aggregate between the oscillating cone and the crusher wa ll (Figure 5-9). Clearance settings on
As a result, the product size distribution varies. When the feed drops into the crusher, the mantle squeezes the rock against the concave surface. When the mantle moves away and the rock drops down further and subject to additional crushing during the next cycle . Material exits the crusher through the open side setting.
Since the rating of crusher motor is high, it is operated either with 6.6 KV or 11 KV. Under the Mains power failure condition crusher ceases its operation and as a result crushing materials remain inside cause jamming and disruption of mining activity until materials are removed and crusher is made ready for next cycle of operation.
The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening (which provides a much larger area than that of the jaw crusher) and the continuous operation principle (while the reciprocating motion of the jaw crusher produces a batch crushing action).
The crushers are designed with built-in tramp relief that allows for the passing of uncrushable objects while remaining in continuous operation and returning to the initial product setting. With a variety of roll surface designs, this crusher is capable of producing a much finer product.
