This series of jaw crusher runs smoothly and has a long service life. It is equipped with a double-wedge discharge outlet adjustment system, which can adjust the discharge outlet of the equipment conveniently and quickly. Even if it is idling, the discharge outlet can be adjusted within a few minutes. When the preset value is reached, it can be automated with the cooperation of the hydraulic system or screw system, which is simpler, safer and faster than the traditional jaw crusher gasket type discharge adjustment system.
When the DHP multi-cylinder hydraulic cone crusher is working, the motor rotates through the pulley or the coupling, the transmission shaft and the cone part to rotate around a fixed under the force of the eccentric sleeve, so that the crushing wall of the cone crusher sometimes approaches From time to time, it leaves the surface of the rolling mortar wall fixed on the adjusting sleeve, so that the ore is continuously impacted, squeezed and bent in the crushing cavity to realize the crushing of the ore.
When working, the rotor is driven by the motor to rotate at a high speed. The material entering from the feed inlet collides with the blower on the rotor, and is broken by the high-speed impact of the blower; the broken material is hit back to the lining board and broken again; Finally, it is discharged from the discharge port. Adjusting the gap between the counterattack frame and the rotor frame can achieve the purpose of changing the size and shape of the material.
Most of the engineering stones are hard rock such as basalt, and the hardness of the material is relatively large. The traditional jaw crusher is not only low in output but also easy to wear. Compared with traditional jaw crushers, PEW European version jaw crusher shows its unparalleled superiority in terms of service life, maintenance rate, and failure rate. Compared with the supporting cone crusher and stone shaping machine, it has That said, the cost is still low.
When working, the motor drives the eccentric sleeve to rotate through the V-belt, large pulley, transmission shaft, small bevel gear, and large bevel gear. The axis of the crushing cone rotates and swings under the force of the eccentric shaft sleeve, so that the surface of the crushing wall sometimes approaches It also leaves the surface of the rolling mortar wall from time to time, so that the material is continuously impacted, squeezed and bent in the annular crushing cavity composed of the fixed cone and the movable cone to be broken.
PFW European impact crusher is a crushing machine that uses impact energy to crush materials. This series of impact crushers have outstanding performance advantages, good discharge particle shape and a wide range of material applications, which enable users to effectively reduce production and construction costs and operation inputs.
Explore our events
A certain construction site introduced a crawler cone crusher mobile crushing station produced by our company for on-site treatment of demolition construction waste. The output of this equipment can reach 200 tons per hour. It has a high crushing ratio and can handle concrete blocks of construction waste with a particle size greater than 700 cm. It can be directly driven into the site for on-site operation. It is convenient and fast, the equipment is easy to transport, and the installation time is short. It is suitable for operation in some remote places such as cities, quarries, open-pit mines, etc.
- 30 Times Square
The equipment of the production line is mainly used to crush marble and iron ore to serve the construction of the national highway network. This is the third cooperation between Red Star and the company, and the fourth aggregate production line ordered by the customer will be installed and commissioned. The materials are first sent to the mobile jaw crushing station for rough crushing. The crushed materials are screened by the vibrating screen and enter the counter-attack mobile crushing station for fine crushing. The crushed products are output by the conveyor belt.

Crawler mobile crushing station
The mobile crushing station is a product of the new era of high-tech crushing technology. Its main characteristics are mobile operation, free walking, more convenient transfer, ensuring the safety of equipment production, and more reliable operation.
Cone Crushing Station
Cone crushers generally have the characteristics of simple crushing operation, low cost, energy saving, environmental protection, and convenient maintenance. At the same time, the crushed material has excellent particle size and better quality.
In the mining and construction crushing industry, the performance of the jaw crusher at the front end of the production line directly affects the quality and operation of the entire production line, which makes people have higher and higher requirements for the capacity and stability of the jaw crusher.
