A jaw crusher is one of different types of crushers often used in crushing rocks, mining s well as in a plant where ore is being processed. In order to break and crush particles, the jaw crusher makes use of what is known to be a compressive force.
Jaw Crushers. In compression crushing, jaw crushers tend to be more of a blunt instrument compared to cone crushers, which is why they’re often used in the primary rock crushing circuit stage. Jaw crushers are also known as “rock breakers” and are used to break up larger, harder materials into more manageable pieces.
The feed size of jaw crusher is 125mm – 750mm, which is the preferred crushing equipment for primary crushing. The feed size of the impact crusher ≤ 500mm and the compressive strength ≤ 350MPa. It is suitable for all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.). The discharge particle size can be ...
Stop the feed to the crusher at the earliest opportunity; ... Jaw crushers operate by squeezing rock between two surfaces, one of which opens and closes like a jaw. Rock enters the jaw crusher from the top. Pieces of rock, that are larger than the opening at the bottom of the jaw, lodge between the two metal plates of the jaw. ...

Try to a keep crushing ratio of 4:1 to get the maximum life out of the mechanical components. Take the maximum feed size divided by the CSS to obtain the crushing ratio. Maximum feed size into the jaw is 80% of the feed opening.
Aug 05, 2021 Double-toggle jaw crusher (the eccentric shaft is pointed behind the swing jaw) Beyond these two types, many other jaw crushers are available like bull-dog jaw crushers and force-feed jaw crushers, etc. but the reason for mentioning these two as the mainstream is that they are the most widely used jaw crushers in the mining industry.
Jaw crusher: The material is crushed between a fixed jaw and a mobile jaw. The feed is subjected to repeated pressure as it passes downwards and is progressively reduced in size until it is small enough to pass out of the crushing chamber.

Jaw gyratory crushers – design and operating principle Technical data The main characteristic of jaw gyratory crushers is their enlarged feed opening which is located on one side of the crusher only. It is normally serrated and, to- gether with the upper part of the mantle, it forms the initial crushing zone. The
Jan 01, 2016 The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate. Solution

The feed material is then fed into the jaw crusher where it first enters the feed opening. Eccentric movement of the jaw stock against the material crushes it slightly so that it can move down the crushing chamber. When the material reaches almost the one third of the total height of the machine, it will experience maximum crushing force and ...

Jaw crushers are also known as “rock breakers” and are used to break up larger, harder materials into more manageable pieces.
Jaw crushers are sized based upon the dimensions of the top feed inlet (gape) or the dimensions of the jaws. For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width.
