Improved flow- and pressure model for cone crushers
Simulation results show that the new flow model has improved the accuracy in the prediction of operating parameters of the rock crusher, such as hydraulic pressure, power draw, and close side setting, CSS. There is also some improvement of the prediction of worn geometry as compared to the old model. 1.

Cone Crusher
Cone crushers have gained such wide acceptance that they may be regarded as standard in the intermediate-range size-reducing machines. A schematic diagram of a cone crusher is shown in Fig. 4.6 A.The drive is similar to that of a gyratory crusher. The inner cone or 'crushing head' is supported by the tapered concentric spindle, which is rotated by the …

Understanding the Cone Crusher Working Principle For …
In summary, a cone crusher operates by rotating the mantle and the concave at high speeds, which compresses and breaks down rocks into smaller pieces. The gap between the mantle and the concave is used to determine the size of the output material, and the adjusting mechanism is used to control the gap and adjust the size of …
