The counterattack crusher (counterattack crusher) is a new generation of counterattack crusher developed based on the specific industrial and mining conditions of the domestic sand and gravel industry. This equipment adopts very new manufacturing technology and unique structural design. The processed products are cubic, tension-free, and crack free, with good particle shape. It can crush various coarse, medium, and fine materials (granite, limestone, concrete, etc.) with a feed particle size of no more than 500mm and a compressive strength of no more than 350MPa. Its discharge particle size can be adjusted, and the crushing specifications are diversified. It is widely used in industries such as hydropower, highways, artificial sand and gravel, and crushing.
The counterattack is composed of a casing, rotor, and counterattack plate. The impact crusher uses impact energy to crush materials. During operation, driven by the electric motor, the rotor rotates at high speed. When the material enters the hammer action area, it collides with the hammer on the rotor and is crushed. It is then thrown towards the counterattack device for further crushing, and then bounced back from the counterattack lining plate to the hammer action area for further crushing. This process is repeated, and the material enters the first, second, third, and counterattack chambers for repeated crushing from large to small. When the particle size of the crushed ore is smaller than the gap between the hammer head and the counterattack plate, it is discharged from the lower part of the machine, which is the crushed product. Adjusting the gap between the counterattack frame and the rotor can change the particle size and shape of the material discharge.
Multi cavity uniform crushing, suitable for crushing hard rocks, with a uniform whole plate structure to make the discharge more small particle size and cubic shape;Low and large feed inlet, convenient for production line layout and feeding size;New wear-resistant materials extend the service life of plate hammers, impact plates, and lining plates;Unique structure, keyless connection, strong rigidity, and large rotational inertia of the rotor. High chromium plate hammer, impact resistant, wear-resistant.;Energy saving, large feed inlet, full crushing function, high production efficiency. Hard rock is broken, but the wear is small, and the comprehensive benefits are high.;The product has a good particle shape, with a cubic shape and good particle shape. The particle size of the discharge can be adjusted to simplify the crushing process.
