spring cone crusher PK hydraulic cone crusher

From the looks of it , spring cone crusher body Equipped with spring around the surrounding iron release over protection device and hydraulic cone crusher is equipped with a hydraulic cylinder body as a protective mechanism . Since the beginning of the last century, the advent of the hp cone crusher to the mid-1980s , has been dominate mechanical spring cone crusher , hydraulic cone crusher limitations due to its own technology has been in a relative disadvantage. With the mechanical spring cone crusher structure continuous improvement and perfection , such cone crusher is widely used worldwide recognition .

Cone crusher is the use of the two cones being inverted gap of crushing equipment. Crushing machine during operation is pulsating forces , particularly the crushing process sometimes mixed with iron , all cone crushers are equipped with a spring protection agencies . Depending on the nature of the different springs can be divided into mechanical spring cone crusher and hydraulic cone crusher spring cone crusher ( referred to as hydraulic cone crusher ) .

But mechanical spring cone crusher there are some key issues:

1. the spring is too small stroke iron protection ;

2. must be limited to the spindle rotation speed of the moving cone assembly , so as not to burn coaster sets of copper ;

3. once the blocking material crushing chamber , cleaning difficult ;

4. adjust the port of discharge is not convenient ;

5. the cone demolition takes too long ;

6. water ring seals often sneak oil , causing oil waste.
