A cone crusher is generally used as a secondary crusher in a crushing circuit. Pre-crushed product (usually 3in minus depending on the cone crusher model) is fed through the top of the cone crusher and flows over the mantle. The vertical cone crusher drive shaft rotates the mantle eccentrically below the concave, or bowl liner, squeezing the product and crushing it between the mantle and concave. Cone crushers are usually run on belt drives driven by an electric motor or diesel engine. Cone crushers are used extensively throughout the aggregate and mineral processing industry.
Application
Spring cone crusher is widely applied in metallurgical, construction, road building, chemical and phosphatic industry. Spring cone crusher is suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, granite, gritstone, etc. 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.
Structure & operation principles
Spring cone crusher consist of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening.
During operation, the motor drives the eccentric shaft shell 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.
