Spring cone crusher is the earliest and one of the most widely-used crushers in the world. The standard type (PYB) is applied to secondary crushing; the medium type (PYZ) and the short-head (PYD) are applied to fine crushing.

PY series spring cone crusher is developed by absorbing the internationally advanced technologies, which is mainly used for the secondary or tertiary crushing. In this machine, overload protection device is adopted in the spring security system, moreover, grease or water is adopted or sealing. According to the applicable ores, crushing chamber are devided into standard type, medium type and short-head type. PY series cone crusher is mainly used for crushing ores with medium or high hardness and it is widely used in metallurgy, building and chemical industries.

Applicable material:Granite, dolomite, river pebble, quartz stone, iron ore, calcite and other materials.

The machine is composed of frame,transmission shaft,eccentric sleeve,bowl bearing,breaking cone,supporting sleeve,adjusting sleeve,feeding part, spring,shaft coupling,lubricating, motor,etc.

while the machine running,the motor drives the flexible shaft coupling,transmission shaft and a pair of bevel gear to make eccentric sleeve running, eccentric Sleeve gives impetus to axial lead to make it dangle. for the dangling,the distance between crushing wall and rolling acetabular wall alternate between ear and far,and material be crushed in crushing cavity by extrusion pressure and impact force.
