The impact crusher can crush large, medium, and small particle-size materials (granite, limestone, concrete, etc.) The maximum feed particle size is less than 500mm, and the compressive strength is less than 350MPa. It is widely used in all kinds of ore crushing, railway, highway, and construction industry artificial sand and gravel production. application area JZF impact crusher is widely used in metallurgy, mining, cement, chemical industry, refractory materials, ceramics, and other industrial sectors, as well as highway construction, water conservancy engineering, construction gravel, machine-made sand processing, and other fields. The main crushed materials are river pebbles, granite, basalt, iron ore, limestone, quartz stone, diabase, etc. Working Principle Impact crushers use impact energy to crush material. When working, driven by the motor, the rotor rotates at a high speed. When the material enters the action area of the blow bar, it collides with the blow bar on the rotor and breaks, and then is thrown to the impact device to be crushed again, and then bounces back from the impact liner. Re-crushing in the action area of the blow bar, this process is repeated, the material enters the first, second, and third counter-attack chambers from large to small and repeats 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 material discharge granularity and material shape.
