SHIBANG  PY series Cone Crusher has been developed to crushe high or medium hardness material ,such as iron ore ,copper ore, limestone, quartz, granite, and sand stones, ect., in metallurgical, construction, road building, chemical, silicate Industries. This crusher has the advantage of reliable construction, high prod activity , easy adjustment and less cost in operation. The spring release system of crusher acts an overload protection system that allows tramp to pass through the crushing chamber without damage to the crusher, use dry oil, water, two kinds of sealed formation. It made plaster stone and engine oil separated, assured reliable performance. The type of crushing chamber depend upon the size of feed and fineness of the crushed product. The standard type is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head is applied to fine crushing.

Features
The PY series crushers crushes by the change of the gap in the crushing cavity .The gap is opened and closed by the gyration of main shaft, which is derived by motor through cone gears. The PY series cone crusher is of high reduction ratio, high performance, low power consumption, and uniform size products. It has been used in the secondary and tertiary crushing.
The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher.
The gap is opened and closed by the gyration of main shaft, which is driven by the eccentric sleeve.
The eccentric sleeve is driven by the motor through elastic coupling , transmission shaft and cone gears .
The cone crusher consists of body frame, transmission shaft, eccentric sleeve, cone bearing, breaking cone, supporting sleeve, adjusting sleeve, feeding part，spring，elastic coupling ，lubrication part , electric part, ect..
