Introduction of impact rock crusher :
Impact crusher is suitable for mining, metallurgy, cement, building materials industry, chemical industry, hydropower and other industries. It crushes hard rock and brittle materials with compressive strength not exceeding 350MPa. Impact crusher is especially suitable for highway hydropower station projects. Aggregate, fabric and artificial sand, such as the crushing of hard materials such as basalt, river pebble, granite, hard lime and so on.
Working principle of impact crusher :
Impact crusher is a crushing machine that uses impact energy to crush materials. When the counterattack crusher works, the rotor rotates at high speed driven by the motor. The material enters the action area of the hammer and breaks with the hammer on the rotor. After being thrown on the counterattack device, it is broken again. Return to the area where the hammer is broken and re-crush. This crushing process is repeated. The materials enter the one, two, three, and counterattack chambers from large to small. The crushing is repeated until the material is crushed to the required particle size. .
Adjusting the gap between the counterattack and the rotor can achieve the purpose of changing the material discharge size and shape.
Counterattack stone crusher performance characteristics
1. The back plate of the impact crusher rotor can withstand the extremely high moment of inertia of the rotor and the impact crushing force of the hammer head.
2. The impact crusher is optimized to be a low-speed, multi-crushing-chamber impact crusher . Its line speed is 20% -25% lower than that of a normal impact crusher, and it has a high production capacity with low energy consumption.
3. The counterattack stone crusher has three levels of crushing and shaping functions, so the crushing ratio is large, the product shape is cubic, and it can be selectively crushed.
4. The counterattack stone crusher adopts a reasonable plate hammer structure, which has the advantages of fast loading and unloading and multiple position changes, which can greatly shorten the time of changing the plate hammer.
5. With new manufacturing technology, Fangda Company has successfully developed a chromium, molybdenum, vanadium alloy material with high wear resistance and high toughness, which solves the problem of crushability of hard materials. Greatly improved the service life of the hammer.
6, Fangda counterattack stone crusher with unique counterattack plate, keyless connection.
7. The PF1315 hard rock counterattack crusher is equipped with a multifunctional hydraulic station, with hydraulic high-speed discharge clearance, stable damping of the counterattack and automatic opening of the body.
