PY Series Spring Cone Crusher
Brief introduction
PY series spring cone crusher is widely applied in metallurgy, construction, road building, chemical and phosphatic industry. It is suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, ratite, grit stone, etc. The type of the crushing cavity is decided by the application of the ores. Standard type is for PYZ (secondary crush); middle type is for PYD (tertiary crush); short-head type is for primary and secondary crush.

Features and benefits
1. High productivity; high quality.
2. Less machine stop time.
3. Easy maintenance and low cost.
4. Unique crushing ability in primary, secondary and tertiary crushing.

Working principle
The crusher consists of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting the discharge opening. During operation, the motor drives the eccentric shaft shells to turn around through a horizontal axle and a pair of bevel gear. The axle of crushing cone swings with the force of eccentric shaft shell so that the surface of the crushing wall is close to the roll mortar wall from time to time. In this way, the ores and rocks will be pressed and crooked and crushed.
