PF SERIES IMPACT CRUSHER
High-reduction crushing with a controlled discharge shape
An impact crusher uses a high-speed rotor and replaceable blow bars to accelerate incoming stone. The material strikes impact plates inside the chamber, fractures along natural weaknesses and is recirculated through successive impact zones until it can pass the discharge opening.
This breakage mechanism is particularly effective where operators need a more cubical finished product, fewer flaky particles and a flexible secondary crushing stage.
- Typical role
- Primary or secondary crushing
- Suitable hardness
- Soft to medium-hard rock
- Finished product
- Well-shaped aggregate
- Plant format
- Stationary or mobile
WORKING PRINCIPLE
Four stages from feed to finished aggregate
- 01
Controlled feeding
Material enters the crushing chamber at a stable rate and falls into the rotor's working radius.
- 02
High-speed impact
Blow bars mounted on the rotor transfer kinetic energy and project the stone toward the impact plates.
- 03
Repeated breakage
Material rebounds between rotor and impact curtains, creating repeated stone-on-steel and stone-on-stone reduction.
- 04
Calibrated discharge
Particles leave when they are small enough for the adjusted gap; oversized pieces remain in the impact path.
WHY CRONUS
Designed around production, maintenance and product quality
Each configuration is selected around the actual feed, moisture, abrasiveness, required output and downstream screening circuit.
Cubical aggregate
Impact breakage improves particle shape for road base, concrete aggregate and manufactured sand preparation.
Heavy-duty rotor
A balanced rotor, robust shaft and securely locked blow bars are engineered for stable high-speed operation.
Adjustable output
Impact curtain position and rotor operating parameters can be matched to the required grading envelope.
Service access
Opening housings and accessible wear zones reduce inspection effort and support faster replacement of wear parts.
Application engineering
Cronus engineers integrate feeders, screens, conveyors and dust-control equipment into the complete plant design.

MAIN COMPONENTS
Wear parts and assemblies that determine performance
Blow bars
Transfer rotor energy to the feed. Material grade is selected for feed abrasiveness and impact load.
Impact plates and liners
Form the crushing chamber and provide the rebound surface for repeated material breakage.
Rotor assembly
Includes rotor body, shaft, blow-bar locking system and wear protection for stable high-speed operation.
Shaft and bearings
Support radial loads and rotor alignment; correct lubrication and temperature monitoring extend service life.
APPLICATIONS
Materials and industries
Best suited to low- and medium-abrasive feed. Highly abrasive silica-rich rock requires careful wear-cost evaluation and may favor a cone crusher in some duties.

FAQ
Impact crusher selection and operation
Practical answers to the questions buyers most often ask before equipment selection.
Ask a project-specific questionWhat is an impact crusher used for?
It is used for primary or secondary reduction of soft to medium-hard rock and recyclable mineral materials where high reduction and a cubical final shape are important.
What materials can a PF impact crusher process?
Common feeds include limestone, gypsum, dolomite, coal gangue, concrete, brick and selected ores. Abrasiveness, silica content and compressive strength must be checked before final selection.
How is an impact crusher different from a jaw crusher?
A jaw crusher compresses material and is often used for primary reduction. An impact crusher uses high-speed impact and is commonly selected for higher reduction and improved product shape.
How is an impact crusher different from a cone crusher?
Cone crushers use compression and usually perform better with hard, abrasive rock. Impact crushers often deliver better shape and reduction on less abrasive feed but may have higher wear costs on silica-rich material.
What capacity can the PF series achieve?
The reference range is approximately 20-550 t/h across the listed models. Actual capacity depends on feed grading, density, moisture, hardness, rotor speed, discharge setting and screen efficiency.
How is the discharge size adjusted?
Product size is influenced by the gap between rotor and impact curtains, rotor speed, feed grading and the downstream screen circuit. Adjustment procedures depend on the selected model.
Which parts wear most quickly?
Blow bars, impact plates, chamber liners and associated locking or protection components are the main wear items. Wear rate is driven by feed abrasiveness, contaminants, throughput and operating practice.
How often should blow bars be replaced?
There is no universal interval. Operators should measure wear profile, monitor vibration and product grading, and rotate or replace bars according to the maintenance manual and remaining safe section.
Can the crusher handle wet material?
Moderate moisture may be manageable, but sticky feed can reduce capacity and cause chamber buildup. Material testing and an appropriate feeder or pre-screen are recommended for wet applications.
Can an impact crusher be used in a mobile plant?
Yes. The crusher can be integrated with tracked or wheeled feeders, screens and conveyors. Transport limits, power source, foundation loads and site movement frequency must be considered.
What information is needed for equipment selection?
Provide feed material, maximum size and grading, bulk density, moisture, compressive strength, abrasiveness, hourly capacity, operating hours, final product sizes and available power.
Does Cronus supply complete crushing lines?
Yes. Cronus can configure feeders, primary and secondary crushers, screens, conveyors, dust-control equipment, electrical systems and spare-parts packages around the required process.
What after-sales support is available?
Support can include installation guidance, commissioning assistance, operator training, maintenance planning, remote troubleshooting and supply of matched wear and spare parts.
