Cone crusher working principle is the same with gyratory stone crusher, but only for intermediate grinding or fine crushing operation Crusher machine. Generally speaking the discharging-material size uniformity of intermediate grinding and fine crushing operation is higher than coarse crushing operation, so must be set passage parallel zone in the under-part of crushing chamber, at the same time must also speed up the cycle speed of crash cone, in order to the material get more than once extrusion in the parallel zone.
The reduction ratio of secondary crusher and fine crushing operation is larger than coarse breaking operation, so the loose volume after crushering have large increase. To prevent the crushing chamber may obstruction as this, on the premise of not increase the nesting population to ensure the required discharging-material size, must by increasing the diameter of the bottom cone to increase the total discharge section.Must be broken by increasing the diameter of the crash cone bottom to increase the total discharge section.
Cone crusher discharge opening is smaller, the non-broken material has mixed to the feeding is easier to bring about an accident, and because intermediate grinding and fine crushing operation required strictly on the discharging-material size, must be adjust the discharge opening in time after the liner wear and tear, the insurance and adjusting device of cone crusher is more necessary than the coarse crushing operation.
