Impact crusher is a kind of crusher that utilizes impact energy to crush materials. When the machine is running, the rotor rotates at high speed driven by the electric motor. When the material enters the crushing chamber area, it collides with the hammers on the rotor, and then passes through the counterattack device to be broken again, and then returns from the counterattack to the area where the hammers act, and repeats the process. The material is repeatedly driven into the first, second and third counter-impact chambers until it is crushed to the desired particle size and discharged through the discharge outlet.
The stone falls directly from the upper part of the machine into the high speed rotating turntable. Under the action of high-speed centrifugal force, the flying stones diverging around the turntable in another part of the turntable will produce high-speed collision and high-density crushing. After the stones hit each other, they will form a vortex movement between the turntable and the machine shell, thus causing multiple strikes and crushing.
Impact crusher can handle materials with side length below 100-500mm, with compressive strength up to 350 MPa, with large crushing ratio, the crushed materials are cubic particles and other advantages. It is widely used in building materials, ore crushing, railroad, highway, energy, transportation, energy, cement, mining, chemical industry and other industries for medium and fine crushing materials. The size of the discharged material can be adjusted, and the crushing specifications are diversified.
Impact crusher, also called impact crusher, is mainly used in metallurgy, chemical industry, building materials, hydropower and other materials that often need to relocate the operation of material processing, especially for highways, railroads, hydropower projects and other mobility stone operations, according to the type of raw materials to be processed, the scale of the finished product and the material requirements of the different configurations of the form.
Advantages of impact crusher:
First, the impact crusher is more effective in dealing with materials with high moisture content, effectively preventing material blockage.
When dealing with materials with high water content, the feed chute and impact plate of the impact crusher can be equipped with a heating device to prevent the bonding of materials. The impact crusher does not need to be equipped with bottom screen plate to effectively prevent clogging.
Second, the impact crusher is applicable to a wider range of material hardness.
The plate hammer of the impact crusher adopts mechanical clamping structure and is firmly fixed on the rotor, which has a large moment of inertia when rotating with the rotor. Compared with the hammer crusher (the hammer head is hanging), the rotor of the impact crusher has greater momentum, adapting to the crushing of harder materials, and at the same time, lower energy consumption.
Third, it can be convenient and flexible to adjust the discharge size, a wide range of adjustment
The impact crusher can adjust the granularity of the discharged material in many ways, such as adjusting the speed of the rotor, adjusting the gap between the impact plate and the grinding chamber, etc. The gap can be adjusted mechanically or mechanically. The gap adjustment can be made mechanically or hydraulically, and the hydraulic adjustment system can be conveniently used to complete the gap adjustment through the on-site operation button or the transportation control system.
The development of the national economy is bound to drive the rise of some infrastructure, the construction of China's infrastructure has entered a boom, so in this context, it is bound to promote the progress of China's mining machinery market. Take the sand and gravel industry as an example, because projects like the railroad, in the development process requires a large number of mechanism sand, concrete aggregate. And in the future, whether it is highway or construction projects, sand and gravel aggregates (or concrete aggregates) have high requirements, and its particle size, quality requirements are increasingly stringent. What does it mean that the impact crusher equipment helps the sand and gravel industry to fulfill the construction demand? Based on the strict requirements of construction sand, but also in order to develop a broader market, the new high-efficiency impact crusher, used in a full set of fine gravel production line, for advanced crushing, with the normal operation of the entire production line.
