Longzhen HP hydraulic cone crusher takes the technology of Nordberg, and our HP220 equals to Metso HP300. We follow the technology of Metso. Technically, Longzhen HP series hydraulic cone crusher is much better than PY series cone crusher. We can see the difference in two aspects.
Firstly, we can see from the operating principle. When hydraulic cone crusher works, Only mantle rotates, and strong main shaft keeps still, make sure less vibration even in high speed of 400 r/min. So the whole machine is more stable. However, spring cone crusher's Nail-shape Main shaft rotates to bring the rotating of the mantle. It causes more vibration when rotating, and also main shaft's easily breaking.
Hydraulic cone crusher’s 400r/min high speed, full crushing cavity, besides,
there is not only extruding, but also milling, which make the stone shape more cubic and a really high capacity. Spring cone crusher only crushes between mantle and concaves, so the stone shape is less cubic and lower capacity.
Secondly, hydraulic cone crusher has separated control systems. The hydraulic system, generally speaking, has three control systems.
