The Speed Of The Rolls Depends On The Angle Of Nip . The larger the angle of nip i, the coarser the feed, the slower the rotational speed must be to ensure nippingor most materials used to make rolls, an angle of nip larger than 30 deg means that the roll will not grip the coal. Doubleroller Crusher Jiangxi Hengcheng Mining
Explains how the Close Side Settings of Crushers controls the product size and ultimately the complete reduction ratio.
zone of a roll crusher and is about to be nipped [4], [5]. For rolls that have equal radii and length, tangents drawn at the point of contact of the particle 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
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.

Jan 01, 2016· The angle of nip for large crushers varies between 21° and 24° (average about 22°) but for curved surfaces it is about 27–30° . The distances of openings between the concave and the breaking head at the top and the bottom ends are usually used to describe the size of the gyratory crusher. The other modes frequently adopted are 1.

A proposal of the nip zone angle determination in high-pressure grinding rolls (HPGR) crush-ing process is presented in the paper. Knowledge of the nip zone angle value makes it possible to deter-mine the real maximum pressing force in the high-pressure comminution. Two methods of determination of this maximum pressure were proposed and verified.
