Product Introduction：

European jaw crusher is a crushing equipment that is quite popular in the market. It is suitable for medium and fine crushing of ores and rocks with a compressive strength not higher than 280MPa, especially for hard and highly corrosive materials. It is suitable for industrial sectors such as metallurgy, mining, chemical industry, cement, construction, refractory materials and ceramics.

Applications:

Sand and gravel yards , mining , coal mining , concrete mixing stations, dry mortar , power plant desulfurization , quartz sand, etc.

Processed Materials:

River pebbles , granite , basalt , iron ore , limestone , quartz, diabase, iron ore , gold ore , copper ore , etc.

Working Principle：

European jaw crusher is mainly composed of frame part, eccentric shaft rotating part, crushing chamber working part, safety device, discharge port adjustment device, etc.

The European version of the jaw crusher adopts the cam-type crushing method. The motor drives the belt and pulley to swing the movable jaw forward and backward and up and down through the eccentric shaft. When the movable jaw pushes the movable jaw plate to move toward the fixed jaw plate, the material is crushed or split. When the movable jaw and the movable jaw plate retreat under the action of the eccentric shaft and spring, the previously crushed or split material is discharged from the lower discharge port of the jaw plate. As the motor rotates continuously, the movable jaw of the crusher periodically crushes and discharges the material, realizing mass production.

 Performance Advantages：

1.Refined Materials and Technologies

Using finite element analysis technology, the movable jaw assembly is made of high-quality steel castings, the heavy eccentric shaft is processed from forging billets, and the bearing seat uses an integral cast steel structure, which not only improves the strength of the equipment and the stability of operation, but also reduces the weight.

2.Save manpower and time

The discharge port adopts a hydraulic wedge adjustment device, which is simple and quick; a centralized lubrication device is used, which makes lubrication more convenient; the jaw plate is fixed by a quick installation method such as a pressure strip and support; multiple methods save manpower and time and improve work efficiency.

3.Improve efficiency and yield The V-shaped crushing chamber has the same width of the actual feed opening as the nominal feed opening, which can meet the requirements of larger feed and higher crushing efficiency. The toothed guard plate is used to increase the effective length of the jaw plate to achieve the purpose of increasing production.

4.Safety device to ensure safety When non-crushed materials enter the crushing chamber, the toggle plate breaks to protect the valuable parts of the equipment from being damaged; the hydraulic cylinder has an overload protection function. When overloaded, the reverse flow valve discharges the hydraulic oil in the hydraulic cylinder, the wedge moves outward, and the discharge port becomes larger.
