when HP hydraulic cone crusher works, only mantle rotates, and strong main shaft keeps still to lessen the vibration in the speed of 400r/min. While the spring can only work at 200r/min with both the mantle and main shaft rotating, and the whole machine is easier to break .So obviously HP is more stable and efficient.
    HP has its edge of separate control in three ways. Firstly, the oil lubrication used for heat or cool the temperature recycles automatically. While the spring cone crusher uses grease without a separated system, so you have to add it frequently, no doubt there is oil leak.
    Secondly, the hydraulic control system is used to recharge the hydraulic cylinder. If the crushing cavity is filled with too much material, the system will automatically lift the bowl and the break the electricity to discharge the big materials. This is controlled all by the system without hand and it can save you a lot from person to improving the capacity.
    Last but not least, the electric control cabinet will simultaneously control all the other two system, and it's easy to operate with the computer. However, in spring cone crusher, you have to control the bowl only all by human's power.
    Also, the totally sealing design keeps the machine from the dust, impurities, so the self protection guarantees the long life span and less cost in mountainous.
