Hard Rock Impact Crusher

Technical Parameters

Working Principle

Hard rock impact crusher is a kind of crushing machine which uses impact energy to crush stone materials. When working, driven by the motor, the rotor rotates at high speed. When the material enters the impact area of the blower, it collides with the plate hammer on the rotor and breaks again. Then it is thrown to the impact device and breaks again. After that, it bounces back from the impact lining plate to the plate hammer action area and breaks again, and this process is repeated. The stone material enters the first, second, third, and impact cavities from large to small and does repeat crushing until the material is crushed to the required particle size and discharged from the discharge port. Adjusting the gap between the impact frame and the rotor can achieve the purpose of changing the size and shape of the stone material.

Advantage of Hard Rock Impact Crusher

1.Hard rock impact crusher can crush the ore and rock with the compressive strength of 350Mpa, with large feeding port, high crushing chamber, high hardness of materials, large fragmentation, and less stone powder.

2.Impact crusherhas a large feeding port, high crushing chamber, high hardness of adaptable materials, large lumpiness, and less stone powder.

3.The energy consumption is small with the energy consumption per unit output is about 1kW/t, which reduces the production cost.

4.The gap between the impact board and the hammer is easy to adjust, which can effectively control the discharging particle size to be cubic with good grain shape. Needle flakes is below 8%, which can improve the quality of concrete products.
