influence of eccentricity in the conical crusher

Adhesion influence on the oil velocity and friction forces ...

2016-2-29 · In conical micro-bearings, the influence of adhesive forces on friction forces is visible in friction forces caused by the hydrodynamic pressure and oil flow velocity. Up to now, the influence of adhesion forces on oil velocity and friction force changes in the conical micro-bearing gap were not considered in an analytical way.

For higher values of X the trend is reversed at lower values of eo and more hydrodynamic effects occur at higher values of ey. The influence of the cone angle under conditions of eccentricity and rotation is shown in Fig. 5.

What is the eccentric throw? — SRP

The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesn''t stay in the center of the chamber – it sweeps around moving closer and further away from the concave. This is what creates the crushing action.

Generally speaking, the problem of conical crusher''s adjustment ring beating or exceeding the rated power is caused by material blockage, feeding eccentricity, uneven feeding, excessive fine material in the feeding, large proportion of mud, and incorrect use of liners. It may also be because the operator has made the CSS too small.
