In the industrial field, there are many industries that develop rapidly with the growth of social economy, such as construction, highway, railway, water conservancy and so on. These industries also drive the demand for sand and gravel, so the sand and gravel factory is an ideal investment project at present. Many users have many questions about the configured equipment when they understand the sand and gravel production line. Such as jaw crusher. Jaw crusher is irreplacable，the process flow of the sand and gravel production line is primary feeding – secondary crushing – crushing and screening. The equipment selected in the primary crushing stage is basically a jaw crusher. Why? Can’t you choose other equipment? Let’s analyze the specific advantages of jaw crusher and the uniqueness of its application.

The jaw crusher has a history of more than 100 years since its birth, and can be widely used in mining, sand and gravel, building materials and other major industries. It is irreplaceable. We see the following aspects.
1、Working method
Each type of crusher works differently and therefore is suitable for different materials. The working mode of jaw crusher is drive and extrusion. The movable jaw of the crushing chamber forms an angle with the fixed jaw. Driven by the motor, the movable jaw moves up and down, and the angle with the fixed jaw changes back and forth to achieve crushing. jaw crusher for sale The functions of materials and structures are relatively simple, but the crushing force and crushing ratio are very large, which is suitable for processing materials with high hardness and large particle size, and everyone knows that after mining, the particle size of ore is relatively large.
2、Operating costs
The main purpose of investing in sand and gravel is for economic benefits. However, if the equipment often needs to be replaced in the later stage or there is a problem in the work, it will cause excessive operating costs and the profit will naturally decline. The vulnerable parts of the jaw crusher are mainly the two jaw plates in the crushing cavity. Since the movable jaw plate and the fixed jaw plate are in direct contact with the material, they are easily damaged under friction and strong crushing force. It adopts optimized and high wear-resistant materials, and has bushings installed on the surface, which greatly prolongs the service life, saves the investment in replacing wearing parts, and effectively reduces the operating cost.
3、Crushing efficiency
Primary crushing equipment is always at the front end of the production line. The crushing efficiency of the equipment will directly affect the operation of the entire production line. CJ series European version jaw crusher is based on the traditional jaw crusher. By optimizing the motion parameters: when the material enters the crushing cavity, it begins to crush. The stroke of the material in the lower part of the crushing chamber will be larger. The curved design of the jaw plate makes the overall work efficiency higher and can achieve an efficient operation level.

Generally speaking, it seems that jaw crusher is undoubtedly a more suitable machine for primary crushing, and the price of jaw crusher is economical, the initial investment is not high, and the later operation cost is low, but it can bring great benefits to users.
This is why most users prefer to choose a jaw crusher. When choosing a jaw crusher, don’t ignore the quality issue because you pay too much attention to the price. The premise of low operating costs is that the quality of the equipment must be reliable, otherwise it is difficult to guarantee that there will be problems in the work.
