The angle of nip in gyratory crushers has definite limitations. In the older straight element crushing chamber, the angle ranges from 20 to 24 . On large primary crushers, using curved or nonchoking concaves and where gravity is of marked aid to nip with the

Effect A Nip Angle In A Gyratory Crusher Samac. Jan 20, 2019 The angle of nip in gyratory crushers has definite limitations. In the older straight element crushing chamber, the angle ranges from 20 to 24. On large primary crushers, using curved or nonchoking concaves and where gravity is of marked aid to nip with the large pieces at the mouth

For example, for relatively large nip angles, material entering the crusher will quickly fall to the bottom of the crushing chamber, and the bottom portion of the jaw faces will tend to wear faster than the top portion of the jaw faces.

Angle of nip varies for large crusher between 21 to 24 . For curved surfaces, the nip varies from 27 to 30 . The distances between the concave surface and the mantle on top and bottom are usually used to describe the size of the crusher. Other characteristic identifications: Bowl diameter at the discharge x

The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees. Too large of an angle causes boiling in the crushing chamber. This is where the jaw plates cannot grip onto the rock, and it keeps slipping up and down, avoiding being crushed. The nip angle gets flatter as the machine is set tighter

Feb 12 2008160183 jaw crusher nip angle the nip angle describes the angle the stationary jaw plate and the pitman make with each other the exact value of this angle isnt quoted or even determinable due to curvature in the jaws themselves but what is important is how wide vs narrow it is wide nip angles can tend to expel material as the jaw closes as a large

Examples of crushers include jaw crusher, gyratory crusher and roll crusher. A double roll crusher consists of two rolls. ... and the two rolls meet to form the nip angle By simple geometry the nip angle between two rolls of radius R, the size of the particle to be crushed i.e. size of the feed ( ) and the

and the nip angle or crushing angle. Standard crushers have nip angles which vary between 25 degrees and 30 degrees. However, by increasing the crusher chamber length, nip angle can be reduced in some cases to less than 20 degrees. When combined with the improved non-choking jaw plates a more efficient crusher results

gyratory, jaw, and cone crushers, are not designed or evaluated for geometry nip angle efficiency. Herein we illustrate a performance gain of a new comminution machine (Conjugate Anvil-Hammer Mill - CAHM first presented at SAG 2011 [3]). The CAHM machine digests rock sizes 400% larger than HPGR

This is dependent on the area of the discharge opening, the properties of the rock, moisture, crusher throw, speed, nip angle, method of feeding and the amount of size reduction. In order to calculate the capacity of crushers, Taggart [8] considered the size reduction, R 80 , as the reduction ratio of the 80% passing size of the feed, F 80, and
