Description
The impact crusher is named according to its working principle, both the use of "stone iron" counter-crushing principle to break the material, is a more fine crushing equipment than the jaw crusher, in the stone production line is mainly used in the fine crushing operation, and jaw crusher cooperation crushing. It has the advantages of large crushing ratio and cubic particles after crushing. It is widely used in building materials, ore crushing, transportation, energy, chemical and other industries for medium and fine crushed materials, the size of the discharge particles can be adjusted, and the crushing specifications are diversified.

Performance Advantages
- Strong processing capacity, high crushing efficiency
High-precision heavy-duty rotor design with large moment of inertia, combined with the overall manufacturing process of CNC machine tools, the rotor running speed is greatly increased, and the processing capacity is significantly increased; The optimized design of involute crushing chamber has high crushing efficiency and good finished particle shape. - Stable and reliable, low failure rate
High wear-resistant material plate hammer, impact plate, high strength and good quality steel, international brand bearings and other multi-directional reliability design, to ensure that the product is always in continuous and reliable operation, and early failure rate is reduced. - Convenient operation and maintenance, low operating cost
The machine adopts Ansys finite element computer aided design, the weight is greatly reduced, and the transportation and installation are more convenient; Multi-functional full hydraulic operating system, ergonomic design theory, innovative design of bearing seat positioning device, etc., make the replacement of wearing parts and operation and maintenance simple and convenient, and reduce the operating cost; Accurately matched drive motor power, the unit product cost control in a good state.
Working Principle
A crushing machine that uses impact energy to break materials. When working, the motor drives the rotor to rotate at a high speed, when the material enters the plate hammer action zone, it is broken by the high-speed impact of the plate hammer, and the broken material is thrown along the tangential direction to the counter plate installed above the rotor to break again, and then springs back from the counter plate to the plate hammer action zone to break again. This process is repeated until the material is broken to the desired size and discharged through the discharge port. Adjusting the gap between the counter frame and the rotor can achieve the purpose of changing the particle size and shape of the material.

Question&Answer
Q:What is the difference between a curved counter plate and a curved counter plate? Which is better?
A:There are two common structural types of counterattack plate: broken line shape and circular arc. The linear impact plate is simple in structure, but it cannot guarantee the most effective impact crushing of the ore. Circular arc counterattack plate, more commonly used with an asymptote shape, the characteristics of this structural form in each point of the counterattack plate, the ore is impacted in a vertical direction, so the crushing efficiency is higher.
Q:They're the usual two breaks. When do you break with a counterattack and when do you break with a cone?
A:First of all, the two applicable crushing materials are different, and the counterattack is suitable for small and brittle materials with hardness and below in crushing, such as limestone, limestone, etc.; Cone breaking can break some materials with greater hardness, such as granite, basalt, tuff, river pebbles and so on.
Secondly, the grain shape of the counterattack is good, the finished product has less corners and more powder; There are more needle flakes in the finished products of conical breakage, and the grain shape is not good, which is why some sand making production lines choose counter breakage.
