Great Wall - Model HPC -Hydraulic Cone Crusher

1. Adopt fixed spindle and small spherical bush structure. Crushing stroke, crushing speed and crushing cavity type are combined reasonably which leads to high crushing efficiency and production capacity is significantly higher than traditional cone crusher.
2. The peculiar principle of "intergranular lamination crushing" significantly increases the cube content in the finished products and also the number of fine-grained materials, which can meet the requirements for the use of high-quality aggregate.
3. When iron or other non-breakable materials enter the crushing chamber, the hydraulic protection device will automatically release them, then automatically reset and back to normal operation state.
4. Hydraulic technology is adopted for the adjustment of discharge mouth and cavity cleaning, which is convenient and fast to operate, reduces downtime and improves work efficiency. 

Movable cone of crusher swings by force of eccentric bushing which makes material between mantle and concave squeezed and rolled. Material is crushed according to its own texture under strength from different directions, finally it would form stable stone shape. End product which meets the requirement would fall from swing gap of mantle, other materials would be crushed again until it meets requirement.
