Read More2016年1月1日 The angle of nip for large crushers varies between 21° and 24° (average about 22°) but for curved surfaces it is about 27–30° [2]. 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.
Read More2016年1月1日 The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle. It depends on the surface characteristics of the rolls. Usually, the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°. 6.2.1. Roll crusher sizes and design

Read Moremum admissible nip angle; the real nip angle of the crusher chamber remained approximately constant. Eventually, the critical moment arrived when the admissible nip angle for the given 8 became smaller than the real angle. The piece could no longer be held by the forces of friction and was ejected.
Read More2016年1月1日 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

Read MoreGyratory and Cone Crusher. In Mineral Processing Design and Operations (Second Edition), 2016. 5.1 Introduction. Gyratory crushers were invented by Charles Brown in 1877 and developed by Gates around 1881 and were referred to as a Gates crusher [1].The smaller form is described as a cone crusher. The larger crushers are normally known as
Read MoreBy 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 distance between the two rolls is given by, Cos θ = (2) where, x1 =diameter of feed particle, R = radius of the rolls, L
Read More2008年2月12日 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 isn't 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 ball
