HPC series hydraulic cone crusher adopts computer optimization design to speed up main shaft speed. The unique crushing chamber replace system can quickly replace components in crushing chamber to meet different size requirement. The friction disc design and rotation of eccentric shaft bushing around fix cone plus more reasonable "labyrinth seal" system are unique features of HPC series, which have more advantages like easier operation, larger application scope, more reliable, more smooth functioning comparing with spring and traditional cone crusher. It is the most ideal equipment for large stone crushing factory and mining industry.
