Initial Feed Size Size Reduction Process Details; Primary Crushing: To reduce large and bulky materials to a manageable size. Jaw Crusher: 500 mm to 800 mm: Reduced to about 125 mm to 150 mm. Large chunks of material are fed into the jaw crusher where strong compressive forces break them down. Secondary Crushing
In-line feeding limits opportunities for the material to clog the Jaw Crusher. 2. Choke feeding. Jaw Crushers work best when the entire crushing chamber is used for material size reduction. Choke feed a Jaw Crusher to maintain a crushing chamber that is at least 80% full.
Here above is shown a family of curves for primary crushing of unscreened feed, such as the average quarry-run material in which the undersize (minus crusher setting) rock is present in proportions normally resulting from blasting operations.
the character of the material. amount of fines in the feed. liner shape; whether the crusher is operated as choke fed or regulated fed ... A jaw crusher size is obtained by looking at its feed opening (gape) and length. As an example, a monster 7959 of 79″ x 59″ (2m x 1.5m) will have its fixed jaws 79″ apart where the feed enters on a 59 ...
Perhaps the first and most fundamental aspects to consider are application and feed material. A variety of crushers exist and each is tailored to meet the demands of very specific applications or materials. The most critical factor with feed material is its degree of hardness. ... depending on the size of the crusher. Cone crushers can form ...
Material exits the crusher through the open side setting. Thus, the top size of the product is determined by the open side setting. ... Therefore, if a 3 mm crusher product is required, maximum feed size to the secondary crusher would be 240 mm. Thus, the feed to the primary crusher should not exceed 2400 mm. Gyratory Operation. Performed in ...

Because the space between the two jaws becomes narrower towards the discharge outlet, the material size is progressively reduced. The gap between the jaws at the discharge outlet dictates the material output size. A typical jaw crusher will have a crushing ratio of between 6:1 to 8:1 i.e. the feed material size is reduced by a factor of 6 or 8.
The primary crusher receives the materials directly from the mine or quarry, and its size reduction ratio ranges from 3:1 to 7:1. The primary crusher can be a jaw crusher, gyratory crusher, or impact …
