HP Series high efficiency Hydraulic Pressure Cone Crusher is a world-level cone crusher developed from the up-to-the-minute technology of Germany. The cone crusher not only improves the production capacity and crushing efficiency, but also widen the applying area, the hardness of materials

range from limestone to basalt. It has a second-to-none crushing performance in the work of medium-size crushing, fine crushing and super fine crushing. The crusher is the improved type of spring cone crusher and can be used to replace ordinary hydraulic pressure cone crusher in the

line of mining and construction. It is the most ideal equipment for large stone crushing factory and mining industry.
Character and technical advantages of Hydraulic pressure Cone Crusher:
HP Series high efficiency Hydraulic pressure Cone Crusher has a better performance compared with spring cone crusher and ordinary Hydraulic pressure Cone Crusher:
1. A high crushing ratio and production efficiency
-the connection of higher turning speed and stroke makes the rated power and passing capacity improved greatly and the crushing ratio and capacity increased.
2. Less spare part consuming and low operation cost
-advanced crushing principal and technical data, reliable operation and low operation cost. All parts of the crusher have anti-wearing protection, which can make the life time of spare parts increased by 30% and the maintenance costs decreased to the lowest. The crusher avoids the disadvantages of impact crusher like low average crushing ratio, large energy consumption, fast abrasion of hammer, impact plate and lining board.
3. between-layer pressuring crushing and better finished product shape.
-The crusher adopts between-layer pressuring crushing principal and the suited turning speed, not the traditional single particle crushing principal. The special crushing cavity can makes the crusher crush materials selectively, thus the proportion of fine product and products of cubic

shape be increased distinctly and products of lump size decreased by a large extent.
4. Hydraulic pressure protection and hydraulic pressure cavity clearing, high automatization and less stop production and repairing time.
-the discharge opening adjusted by hydraulic pressure and overload protection makes performance of the crusher increased by a large extent, the maintenance and operation easier, the repairing time shorter; the bidirectional metal releasing hydraulic pressure vat makes slab pass through crushing cavity; the crusher can discharges materials automatically when the hydraulic pressure works under the conditions of iron passing and instantaneous overloading, thus there is no trouble of stopping the crusher to discharge materials by hand.
5. Thin oil lubrication makes the life time increased.
-Unique design of thin oil lubrication system prolongs life time of the crusher, high performance and not touchable labyrinth airproof part blocks off the dust and remove the common disorders like the mixture of oil and water in spring cone crusher.
6. Manifold crushing cavity
-It is only need to change fixed cone lining board and movable cone lining board; the type of crushing cavity can be changed from standard coarse cavity to short head fine cavity, which can meet various kinds of need.
7. Easy maintenance and operation.
-all parts of HP cone crusher can be assembled, disassembled and repaired from the top and side part, including the fixed cone and movable cone. For the changing no need to disassemble the crusher body and fasten the bolts. Hydraulic motor makes the performance of crusher better.
8. The crusher can provide customers a higher capacity, better product shape, and easy be operated.
Common problems for Hydraulic pressure cone crusher:
The performance of ordinary hydraulic pressure cone crusher can acts as the reference for the performance of HP series cone crusher. As a composing unit of the production line, its performance can be influenced by other units like feeder, belt conveyor, vibrating screen, motor, transmission part and hopper, etc.Take care of the following factors which can influence the performance of hydraulic pressure cone crusher:
1. choose the right crushing cavity according to the materials be crushed;
2. the feeding size should be right;
3. materials distributed equally around the round of crushing cavity;
4. automatically control system;
5. discharge opening of cone crusher works normally;
6. the model of belt conveyor be seasoned with the max. processing ability of the crusher;
7. choose the right screen model for advance screening and closed screening.
The following character can decrease the capacity of Hydraulic Pressure:
1. the fine particle with size less than that of feeding hole surpass the max. capacity of the crusher by the extent of 10%;
2. Sticky materials mixed in the feeding;
3. no feeding control;
4. materials allocated improperly around the crushing cavity;
5. the recommended power not used;
6. screening capacity not enough;
7. discharge opening now works normally;
8. Materials too hard or too elastic.
