PY-series Cone Crusher Structure:

    Zhengzhou Toone PY-series cone crusher consist of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening.
    Zhengzhou Toone PY-series cone crusher divided into coarse cone crusher, cone crusher and the fine crushing crusher according to the different needs of users. Which is helpful for production of different size ore materials. Users ca choose the machine type according to their actual requirements.

Working principle of PY-series Cone Crusher:

    1. When Zhengzhou Toone PY-series cone crusher is working, the eccentric sleeve is rotated by the motor. The eccentric sleeve drives the transmission shaft and cone part to make swing movement. When they swing to the extent that the surface of the crushing wall is close to the roll mortar wall, the rocks and ores are pressed and crushed.
    2. Joint between supporting sleeve and frame is compressed by spring. When metal block and other materials that can not be crushed fall into the crusher, spring will be out of sharp and discharge the objects.
    3. When the materials that can not be crushed pass through the crushing chamber or the machine overloads, the spring safety system makes the cone discharging hole become larger. When objects are discharged from crushing chamber, discharging hole will automatically reset. Cone crusher resumes normal operations.
    4. The surface of crushing chamber is covered with wear-resisting high manganese steel lining plate. Size of discharging hole can be adjusted hydraulically or manually.
