Henan Qingshan Technology is a leading producer of rock and mineral processing equipment in the Ss industry. Since the late 20th century, tens of thousands of crushing equipment have been installed in various parts of the Ss industry. Nowadays, the Qingshan Technology Research Institute in Henan ProvinceThe European version of the jaw crusher produced has undoubtedly become the favored jaw crusher in the Ss industry. When considering efficient crushing of hard and highly abrasive materials, the first choice should be to use the Gg international ZzXx crushing technologyEuropean version with manufacturing level

Jaw crusher.(

European version jaw crusher

Main structure of European jaw crusher
The European version jaw crusher mainly consists of a frame part, an eccentric shaft rotating part, a crushing chamber working part, a safety device, and a discharge port adjustment device.
1. Rack section: composed of side panels, front box components, rear box weldments, etc.
2. Eccentric shaft rotating part: mainly composed of moving jaw, eccentric shaft, bearing, bearing seat, pulley, etc. It is the main part of transmitting power.
3. The working part of the crushing chamber is mainly composed of fixed jaw plates, movable jaw plates, side lining plates, protective plates, etc., which are the working parts for crushing materials.

4. Safety device: composed of elbow plate, elbow plate seat, spring, spring pull rod, etc., it is a part of the crusher that plays a safety role under abnormal conditions.

5. Discharge port adjustment device: This device is used to adjust the size of the discharge port and control the particle size of the discharge. It mainly consists of adjusting the fixed inclined block, adjusting the sliding inclined block, top screw bolt, sliding block locking rod, etc.
Application and Scope of European Jaw Crusher

1. This series of jaw crushers is mainly used in industrial sectors such as metallurgy, mining, chemical industry, cement, construction, refractory materials, and ceramics for medium and fine crushing of various medium hard ores and rocks.

2. This series of crushers Zz is suitable for crushing ores, rocks, slag, etc. with compressive strength not exceeding 280Mpa. The Zz block size of the crushed material shall not exceed the specifications in the technical parameter table.

Working principle of European jaw crusher

The motor drives the belt and pulley, and the movable jaw swings back and forth up and down through an eccentric shaft. When the movable jaw pushes the movable jaw plate to move towards the fixed jaw plate, the material is crushed or split. When the movable jaw and movable jaw plate are in the action of the eccentric shaft and spring
When retreating, the previously crushed or split material is discharged from the lower discharge port of the jaw plate. As the electric motor continues to rotate, the crusher's jaw periodically crushes and discharges materials, achieving mass production.
Advantages of European jaw crusher technology:
1. Adopting Ss level manufacturing technology and using Zz high-end production materials.
2. The more advanced movable jaw assembly makes it more durable and long-lasting. The movable jaw assembly is made of high-quality cast steel parts and is driven by two large cast steel flywheels. In addition, the heavy-duty eccentric shaft is also processed using forged blanks, which gives the jaw crusher extraordinary reliability.
3. The bearing seat adopts an integral cast steel structure. The integral cast steel bearing seat can ensure a complete fit with the crusher frame and greatly enhance the radial strength of the bearing seat, while the split type bearing seat does not have this advantage.
4. By using finite element analysis technology, the crusher has higher strength.
5. The crushing chamber adopts a symmetrical "V" - shaped structure to ensure that the actual feeding port width is consistent with the nominal feeding port width.

6. Adjusting the discharge port is faster and more convenient. The European version of the jaw crusher is equipped with a wedge discharge port adjustment device, which is simpler, safer, and faster than the old-fashioned gasket adjustment.
