· Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute mediumhard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.

Double Roll Crusher Osborn Double Roll Crushers can be used for primary and secondary crushing. The Double Roll Crusher is generally regarded as a 4:1 feed to product ratio crusher, however in some instances, dependent upon material friability and hardness, it is possible to achieve a 6:1 crushing ratio.
Definition of angle of nip. In a rockcrushing machine, the maximum angle subtended by its approaching jaws or roll surfaces at which a piece of ore of specified size can be gripped. See Also: nip.

Roll crushers SlideShare. Apr 24, 2015 A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls; 5. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle.
6. Nip angle of the crusher machine. For the jaw crusher and cone crusher, the nip angle is the angle between the two crushing faces (when the two faces are closest to each other). For the double roll crusher, the nip angle is the angle of two tangent lines that derivate from the contact point between the ore block and roller.

· The nip angle is affected by the distance between the rolls. 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°.
angle of nipping derivation roll crusher Crusher Mining Usually the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°.+ LCYL)]082 kW.
A proposal of the nip zone angle determination in highpressure grinding rolls (HPGR) crushing process is presented in the paper. Knowledge of the nip zone angle value makes it possible to determine the real maximum pressing force in the highpressure comminution. Two methods of determination of this maximum pressure were proposed and verified.
Nip angles were also calculated using the widely used Johanson model. However, wall friction measurement on serrated roll surfaces could be impractical. The Johanson modelderived nip angles could differ by 3°8° just by altering the roughness of the
Nip Angle For Roll Crusher. 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. Get Price
Results of the nip zone angle calculations according to both methods are similar and show that the nip zone angle is (1989) run an investigations over the pressing forces in roller crushers.
