Features a counterattack crusher, impact crusher feed opening, high crushing chamber, can crush high hardness, block degree materials. 2, back-breaking counterattack board and the board hammer gap can be easily adjusted, can effectively control the expected size, particle shape better broken material. 3, crusher overall structure is compact, machine rigidity, the rotor has a large moment of inertia. 4, crusher equipment high chrome hammer, impact, abrasion, impact force, is ideal for crushing equipment. 5. Impact Crusher keyless access, easy maintenance, economical and reliable. 6, back-breaking equipment crushing full-function, high efficiency, small mechanical wear, high overall efficiency. Impact crusher working principle of impact crusher is a use of impact energy to crush materials broken machinery and equipment. When the machine work, driven by the motor, the high-speed rotation of the rotor, while the material into the zone plate hammer, hammer and rotor material impact crusher, and then was thrown back on the device again broken, and then from the back liner bounced back on board again broken hammer district, this process is repeated until the material is broken to the desired size, from the discharge port. The operator to adjust the gap between the impact rack and rotor, changing the material until it reaches the expected size and shape of the material purposes.
