The JOYAL Hydraulic Cone Crusher is widely used for secondary and fine crushing in the fields of mining, building materials, metallurgies and so on. The hydraulic cone crusher can crush materials with middle and high hardness such as ironstone, copper ore, granite, basalt, cobblestone, marble, limestone and so on. The Hydraulic Cone Crusher is widely used in highly automatic crushing line which has strict requirements for the fineness of the end products and crushing ratio.

Features

1. Unique hydraulic protecting system, including protecting oilcan, locking oilcan and hydraulic driving oilcan, which can not only protect the machine, but also deal with operational troubles without disassembling the whole machine.
2. Easy to operate, reliable performance and adjustable in terms of size of the end products.
3. The crushing chamber is specially designed according to particles-layer- pressure principle. The special chamber and the suitable rotating speed improve the crushing ratio and capacity, and also the percentage of cubic products.
4. If something abnormal happens, for instance, the iron is fed into the crushing chamber or there is a jam in the chamber, the up-cover of the machines will be lift up and the materials will be discharged automatically, thus eliminating the chance of machine stoppage to discharge the material by workers. Besides, it’s easy to maintain, and the cost is much lower than Spring Cone Crusher.
5. Unique hydraulic device and diluted oil lubricating system ensures the reliable performance of the equipment. The labyrinth-like sealing obviates the mixture of water and oil, which is hard to avoid in the traditional Spring Cone Crusher.
6. The mantle and bowl liner are made of high-manganese steel. The special design of crushing chamber and particles-layer- pressure protection device reduce the abrasion, extending the service life of spare parts by 30%-80%.

Working Principle

During the working process, the eccentric shaft will force the motor to make a swing movement at a fixed point by the conveyor, counter shaft, couplings, and the cone parts, which can make the crushing cavity close or leave the rolling shirakable now and then.And the ores will be crushed by shock, crack and warp.And HP Cone Crushers spring secure system is a kind of overloaded protection equipment, which can let the non-metal materials pass the crushing cavity with no harm to the machine.Adoption of the glycerol or water seal forms can seprate the stone powder and lubricating oil, which ensure the reliable work.The spring secure system will take effects and the discharge opening will become largest so that the foreign bodies can be discharged from the discharge opening when the non-crushed materials can not pass the crushing cavity or the overloaded phenomenon has happened on the machine.If the foreign bodies get stuck in the cavity, we can continue to increase the discharge opening and let them pass the cavity.Due to the spring, the discharge opening wil recover and go back to the normal work.
