Working principle

Working Principle

The working principle of the impact crusher can be summarized as a process of "three-stage crushing and cyclic refinement":
 
1. The material first enters the high-speed rotating rotor area and is strongly impacted by the plate hammer at a linear speed of 30-50m/s (primary crushing);
2. The material is then ejected to the impact plate for collision and crushing (secondary crushing), and at the same time collides with other materials in the chamber to achieve free crushing (third-stage crushing).
3. By intelligently adjusting the gap between the impact plates and the rotor speed, the system can accurately control the number of crushing times and residence time of the material in the chamber to ensure that the finished product particle size is uniform and meets the standard, and the particles that do not meet the standard continue to be cyclically crushed until they are discharged.
 
This multi-stage impact crushing mechanism enables the impact crusher to have the dual advantages of efficient crushing and high-quality particle shape.

PFW Impact Crusher - FAQ

Q1. What is the difference between the PFW (European-type) impact crusher and the old PF series?

The PFW series upgrades the PF design with a hydraulic opening frame, a reinforced heavy rotor, optimized two- or three-crushing-chamber geometry, and high-chromium blow bars. It delivers a higher crushing ratio, a better cubic product, and much faster liner changes, but the core impact-crushing principle is the same.

Q2. Can the PFW impact crusher crush granite or basalt?

Yes, as a secondary or tertiary crusher – i.e., after a jaw or gyratory crusher has already reduced the rock. It is not recommended as the primary breaker for very hard, highly abrasive basalt or river pebble, because the blow bars will wear quickly. In that case, pair it with a jaw crusher or choose a cone crusher for the hard stage.

Q3. What end product size can I get?

Discharge size is adjusted by changing the gap between the last impact plate and the rotor. Typical finished fractions are 0–20 mm, 20–40 mm and 40–70 mm; for finer products, the PFW is usually followed by a VSI sand maker or a screening plant. The exact output depends on the material's work index and the gap setting.

Q4. How do I reduce wear cost on the blow bars?

Use the correct alloy for your material (high chrome for abrasive rock, martensitic for impact-heavy duties), avoid oversize feed, keep a steady and controlled feed rate, rotate the blow bars when one edge is worn, and avoid running the crusher empty with no choke feed. The hydraulic gap adjustment also helps keep a consistent, efficient setting.

Q5. Is a PFW impact crusher suitable for concrete and asphalt recycling?

Yes – it is widely used in C&D waste recycling. It crushes reinforced concrete rubble (with rebar separation via an overband magnet downstream), crushed brick, and reclaimed asphalt pavement into reusable aggregate. Because the impact action liberates mortar from the stone surface, the recycled product is often cleaner than jaw-crushed material.
