Zhengzhou Great Wall Heavy Industry Machinery Co., Ltd. is one large supplier of cone crusher. There are three types of cone crushers in our company; they are spring cone crusher, CZS high efficient cone crusher and hydraulic cone crusher. High efficient hydraulic is the latest high-hard materials crusher at the basis of many years production of, through the improvement of crushing chamber and optimized design of dynamic and kinematic aspects, which have the following features:

1) Long service life of quick-wear parts, large capacity, more suitable for crushing high hardness materials;
2) With hydraulic protection and hydraulic chamber cleaning, the machine is high-automatic. If something abnormal happens, such as iron is feed into the crushing chamber or there is a jam in the chamber, the machine will lift up the cover and discharging the materials automatically.
3) In recent years, the cone crusher is widely used in the iron ore industry, as well as basalt, pebbles, granite and so on. There are hundreds of customers at home and abroad.

In addition, the hydraulic cone crusher has other special features as follows:
1. The hydraulic cone crusher crushing cavity is special designed according to particles layer pressure principle, the special cavity and the suitable rotary speed improve crushing ratio and capacity, so does the cubic product percentage.
2. With hydraulic protection and hydraulic cavity cleaning, the machine is high automatic, if something abnormal happens, such as iron is feed into the crushing cavity or there is a jam in the cavity.
3. The mantle and bowl liner are made by high abrasion materials.
4. Hydraulic cone crusher is adjusted by hydraulic device and lubricated by diluted oil. The labyrinth seal eliminates the defect of
