When it is working, motor's rotating makes swinging motion around one circle of fixed point by pulley or linkage shaft device, transmission shaft of cone crusher and cone crusher's taper section under the forced move of eccentric set. It makes the crushing debir of cone crusher is sometimes near and sometimes deviation, it is installed in the rolling mortar wall of adjustment ring, and makes the ores be impacted, squeezed and bended in the crushing cavity and realizes the crushing of ores.
PY series cone crusher is quite suitable for crushing stones which is hard enough and middle-hard. It has higher technical content , so it has longer useful life time and high efficiency. PY series cone crusher makes fine products take a bigger proportion which reduces secondary crushing and gets much more final products. Working life of easy-worn parts of the product is long, so it is easy maintenance, less investment at one time, smaller operating cost and higher general economic profits.
