2.1.5 Thickness of the RollFigure 1 is the geometry of a double roll crusher with a spherical particle about to enter the crushing 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 angleRoll Crushers TAKRAF TAKRAF GmbH,25: 2,500 mm pitch circle roll diameter. 37: 3,700 mm roll length. Our largest roll crushers are equipped with TAKRAF designed and developed gearboxes that are specifically applicable to heavyduty crushing applications at up to 1,500 kW of motor power. Each gearbox is manufactured and tested at our workshop in Lauchhammer, Germany.Diameter of Roll Crusher for the Given Feed and Product Size,Diameter of Roll Crusher Home> ChE Learning Resources > Solved Problems > Mechanical Operations> A pair of rolls is to take a feed equivalent to spheres of 3 cm in diameter and crush them to spheres having 1 cm diameter. If the coefficient of friction is 0.29, what would be the diameter of rolls? Angle of nip = 2 α
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 Mechanical Operations Questions and Answers Size,Explanation: The angle of nip i.e. cos α = r+d/r+R, where R and r are the radius of feed particle and the roll and d is the diameter of largest possible product. Roll crusher c) Jaw crusher d) Gyratory Mill View Answer.

In a roll crusher, rolls of diameter 1 m each are set in such a manner that minimum clearance between the crushing surfaces is 15 mm. If the angle of nip is 31o.,the maximum diameter of the particle (in mm) which can be crushed is ____________ (rounded off to third decimal place). Roll crusher Cos ∝ = r + Rp / r + Rf d = 1m min clearanceMechanical Operations Chemical Engineering Questions ,38. Half the angle of nip, (α), for a roll crusher is given by (where, dr, dp and df are diameters of crushing rolls, feed particles and rolls gap respectively).Determination of the nip zone angle ,Knowledge of the nip zone angle value makes it possible to determine the real maximum pressing force in the highpressure comminution.

The closedside 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.
