This machine is widely used for hard and middle-hard stones. It is the original and first developed cone crusher stone mostly for the secondary crush. As a long-term constructor and businessmen, you need a machine that can bear longer crushing without frequently changing the wearing parts to save the total money. Though spring crusher is of higher price comparing impact crusher, you can save large sums of money to do the maintenance, and the high efficiency and technology it brings can help you make it once and for all.
    While, as the early-developed cone crusher, PY is weak in the a few aspects, so you ought to think twice before you really make the choice. First, PY has relatively low capacity. Also, the oil it uses is grease, which will turn to solid when is gets cold. Third, while it is working, the mantle and main shaft swing with the a speed under the same electrical voltage. Once the system is stuck by the bigger rock, it has to break down, adjust, and start again.
    One thing to advice: you can also choose from what type of rock you are to process. If you use the soft rock like limestone, you can choose the impact crusher with lower price; if the hard rock, then you may need the cone crusher for the sake of long-term consideration.
    If you think the PY cannot meet your need technically, we recommend you to choose HP Hydraulic cone crusher, which is our company's most strength.
