Product Description

Production Introduction 
Jaw crusher is a common crushing equipment in mine crushing production. Because of its simple structure and reliable work, it is highly praised by customers. The highest compressive strength of the jaw crusher produced by our company is 320MPa. It can meet the crushing process of a variety of materials, and a variety of models are available for you to choose from.



Advantages of Jaw crusher 

Jaw crushers have been developed for a long time. They have been used since 1806 and have been widely used by the public. They have been making progress and innovation with the progress of science and technology, and are still occupying a leading position in mine production. however, there are some reasons of why Jaw crushers have been so popular and what are the advantages of jaw crushers: 

1. The structure is simple and easy to operate, and the maintenance is convenient and quick: after reasonable design, the overall structure of the equipment is simple and efficient, and the crushing ability is enhanced while improving the performance of the machine. The operation of the whole equipment is simple in the process of use, which makes the daily maintenance work more convenient and faster, and reduces the downtime. 
2. Low noise at work, environmental protection and high efficiency: designed in strict accordance with environmental standards, equipment in the work of low noise, can reduce noise pollution. At the same time, it can be equipped with dust removal, resulting in less dust. Thus, it can effectively protect the surrounding environment and reduce pollution. 
3. The crushing process is adopted, and the digital parts processing equipment is used to make the internal structure precise. If the deep cavity is broken without dead zone, the material will not be blocked in the crushing cavity, which improves the production efficiency. 
4. The equipment is flexible and versatile: the adjustment range of the discharge port is large, which increases the flexibility of the equipment and can meet a variety of processing requirements. And the equipment structure is reasonable, the occupation area is small, can play a big role in the limited space. 
 

Although there are many advantages, but in the choice of regular quality or good equipment, otherwise everything is nonsense. In addition, the correct use, regular inspection and maintenance is also very important, otherwise no matter how good equipment, but also almost as much as a pile of scrap iron. If you want the equipment to work properly, the output, efficiency, discharge of finished materials to meet the standard must do a good job of daily work.

Working Theory 
The jaw crusher is working, the movable jaws make periodic reciprocating motions to the fixed jaws, sometimes approaching and sometimes leaving. When approaching, the material is crushed, split, and impacted between the jaws; when it is removed, the broken material is discharged from the discharge opening by gravity.
In the process of breaking large stones into small stones, the first crusher is usually a "main" crusher. The longest and most solid crusher is a jaw crusher. When feeding the jaw crusher, the material is poured from the top inlet into the crushing chamber containing the rake teeth, and the rake teeth force the material against the wall of the chamber and break it into smaller stones. An eccentric shaft is supported for the movement of the caries, and the eccentric shaft penetrates the frame of the fuselage. Eccentric motion is usually generated by flywheels fixed at both ends of the shaft. Flywheels and eccentrically supported bearings often use spherical roller bearings, which must withstand large shock loads, abrasive sewage, and high temperatures.
