1. Jaw crushers The jaw crusher is V shaped consisting of two jaws – one movable and the other fixed making an angle of 10-20 ° between them. The materials for size reduction are introduced between the two jaws at the top and compressive force is exerted by the movable jaw. The size reduction happens from top to bottom with larger

Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.
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).
HOW DO JAW CRUSHERS WORK? / THE WORKING PRINCIPLE OF JAW CRUSHERS. All jaw crushers feature two jaws: one of which is fixed while the other moves. The working principle of jaw crushers is based on …
Jaw Crusher Working Principle. A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or …
Working Principle of a Jaw Crusher. A jaw crusher mainly works on the principle of reciprocating motion exhibited by the moveable jaw of the jaw crusher. The repeated movement of the jaws results in the development of compression force that further causes the breakdown of the rock or the ore placed …

The feed size of gyratory crusher varies from ____ a) 150-190 mm b) 200-800 mm ...
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).
Typically, jaw crushers produce less fine material than impact crushers. The reduction ratio of a jaw is approx. 4 to 1. Fines are necessary to meet certain gradations and increase material compaction. This is the reason why a jaw crusher is predominenatly used as a primary crusher for an intial reduction in size or to produce a non-spec material.

The feed-material, which has passed a 0.75-in. screen-opening, is thus reduced in a single operation to a size at which 94 per cent, passes 100-mesh screen, at the rate of 60 tons per hour. This use of rolls carries the principle of choke-crushing to so extreme a limit as to involve practically a new function.
The movable jaw compresses material against the fixed jaw, crushing the material to the desired size. The material exits the jaw through a discharge opening, allowing it to be further processed or used for various purposes like construction materials, road building, and much more. The working principle of a jaw crusher is straightforward.
