PF series impact crusher, Chinese name is PF impact crusher, foreign name is PF impact crusher. The equipment has the advantages of simple structure, large crushing ratio, low energy consumption, high output, and cubic shape of materials after crushing. It is widely used in industrial sectors such as mining, cement, construction, refractory materials, coal, glass, etc., for medium and fine crushing of various medium-hard materials with compressive strength not higher than 100Mpa, such as limestone, dolomite, clinker, slag, coke, coal, etc.

 

 

The working principle of PF impact crusher is based on high-speed impact principle. When working, the stone falls directly from the upper part of the machine into the high-speed rotating turntable, and the rotor rotates at high speed driven by the motor. The material entering from the feed port collides with the plate hammer on the rotor, and under the action of high-speed centrifugal force, it collides with the other part of the flying stones that are diverted around the turntable in an umbrella-shaped manner to produce high-speed collision and high-density crushing. The crushed materials are then impacted onto the lining plate for further crushing. After the stones hit each other, eddy currents are formed between the turntable and the casing, causing multiple impacts, friction, and crushing, and finally discharged from the discharge port. This forms a closed-loop multiple cycle. Adjusting the gap between the impact frame and the rotor frame can achieve the purpose of changing the material discharge particle size and shape.

 

 

1. High efficiency and energy saving: This machine is optimized and designed as a low-speed, multi-crushing chamber impact crusher. Its linear speed is 20%-25% lower than that of general impact crushers, and high production capacity is obtained with low energy consumption.

 

2. Unique structure: Using keyless connection and new manufacturing technology, a highly wear-resistant and high-toughness chromium, molybdenum, and vanadium alloy material has been successfully developed, which solves the problem of crushing hard materials and greatly improves the service life of the hammer.

 

3. Good crushing effect: It has the functions of three-stage crushing and shaping. The finished product is in the shape of a cube, without tension cracks, with good particle shape, and the discharge particle size is adjustable, simplifying the crushing process.

 

4. Easy maintenance: PFW hard rock impact crusher is equipped with a multifunctional hydraulic station, which has hydraulic high-speed discharge gap, impact plate stable vibration reduction and automatic opening of the machine body, which is convenient for maintenance and replacement of wearing parts.

 

5. Strong adaptability: multi-cavity uniform crushing, suitable for crushing hard rock; low and large feed port, convenient for production line layout and increasing feed size.
