Longer-service-life PF series impact crusher

Use the hydraulic to open, easy to maintain and change wear-parts.New anti-abrasive material makes longer service life of impact

PF series impact crusher

PF series impact crusher is mainly used in secondary crushing,and can crush material its crushing cpmression strength not more than 320Mpa. It is suitable to produce aggregate for highway,hydroelectric and building material industry,etc.

Featrues and benefits

1. Many cavity to crush,suitable for crushing hard rock.

2. Reasonable design of leveling plate making charge finer and cubic without interior cracks.

3.Low and big feed opening makes the production line easy to arrange and increase the size of feeding material.

4. Use the hydraulic to open, easy to maintain and change wear-parts.

5.New anti-abrasive mateial makes longer service life of impact bar,inmpact plate and liner.

1) Applicationof stone impact crusher

Impact Crusher is mainly used to crush many kinds of large, medium, small materials whose side length is less than 500mm, and compression resistance should not be more than 350Mpa. The impact crusher is widely used in hydroelectricity, highway, artificial stone and sand, building material, etc. 

 2) Characteristics of stone impact crusher: 

1. Big feeding open, high crushing cavity,suitable crushing the materials with high hardness, big block and less final stone powder.

2. Easily adjust the gap between the impact plate and plate hammer, control the final size effectivly and good grain size;

3. Compact structure, strong steel characteristics of the machine and motor with large moment of inertia

4. High chrome hammer, Impact and abrasion resistance and great impact

5. Keyless access, easy maintenance, econimical and reliable

6. Full Broken function, high productivity, little mechanical wear and high overall efficiency

  

3) Working Principle of stone impact crusher:

 When the impact crusher works, the motor drives the rotor rotate of the impact crusher with high speed, on the rotor where installed the hammers. When the materials get into the area which the hammers effect, under the impact function of the hammer at a high speed, the materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects for being recrushed. The materials from large to small all to be crushed at the impact chamber repeatedly. The process won’t stop till the material are crushed to the required size and then discharged from outlet of the impact crusher.
