Secondary Crushing Equipment for Aggregate and Mineral Processing
LIPU impact crushers are designed for secondary crushing of medium-hard materials in aggregate production, quarrying, mineral processing, construction waste recycling, and other industrial applications.
Different models can be selected according to feed size, material hardness, required capacity, final product size, and the complete crushing process.
An impact crusher is a crushing machine that uses high-speed impact force to break material.
Material enters the crushing chamber and is struck by the rapidly rotating blow bars mounted on the rotor. The material is thrown toward the impact plates, where it is further broken by repeated impact and collision.
Compared with compression crushers, impact crushers are often selected when product shape, particle grading, and secondary crushing performance are important.
They are commonly used after a jaw crusher or other primary crushing equipment.
LIPU provides different impact crusher configurations for quarrying, aggregate production, mineral processing, and construction waste recycling. The suitable type depends on feed size, material characteristics, required capacity, final product size, and the overall crushing circuit.
PF series impact crushers are widely used for secondary crushing of limestone, dolomite, sandstone, concrete, and other medium-hard materials.
Typical features include:
PF models are available in different rotor sizes and capacities to match different production requirements.
For larger feed sizes or higher-capacity applications, LIPU can provide heavy-duty impact crusher configurations with larger crushing chambers and strengthened rotor structures.
These machines are generally selected for:
Specific rotor size, motor power, and chamber configuration should be selected according to the actual material and production requirements.
Impact crushers can also be integrated into mobile crushing plants for projects requiring flexible relocation and shorter site installation time.
A mobile impact crushing plant can combine:
This configuration is commonly used for quarry projects, road construction, demolition waste recycling, and temporary aggregate production sites.
The final crusher type and configuration should be selected according to material hardness, abrasiveness, feed size, capacity, required aggregate specifications, and site conditions.
Impact crusher performance depends on the complete crushing system rather than the crusher alone.
The feeding system, rotor configuration, blow bars, impact plates, discharge adjustment, screening equipment, and conveyors should be matched according to project requirements.
For complete aggregate production lines, an impact crusher can work together with primary crushing, screening, conveying, and return-material systems.
LIPU impact crushers can be used for a range of medium-hard rocks, ores, and recycled materials.
Typical materials include:
Typical applications include:
Material hardness and abrasiveness should always be considered before selecting an impact crusher.
For highly abrasive hard rock, a cone crusher may be more suitable depending on the application.
Material enters the crushing chamber through the feed opening.
The high-speed rotor drives the blow bars to strike the incoming material.
After the initial impact, the material is thrown toward the impact plates and is broken again.
This process may repeat several times before the material becomes small enough to leave through the discharge opening.
Particle size is controlled by factors such as:
A typical impact crusher includes:
The rotor and blow bars provide the main impact force.
Impact plates receive the thrown material and provide secondary breakage, while the adjustment system helps control the discharge size.
An impact crusher is especially suitable when the project requires secondary crushing and good particle shape.
It is commonly selected when:
However, an impact crusher is not the best choice for every material.
For hard and highly abrasive rock such as some granites, basalts, and iron-rich ores, wear costs may increase. In these cases, a cone crusher may offer better long-term wear performance.
The final selection should therefore consider both crushing performance and operating cost.
An impact crusher normally works as part of a complete crushing and screening system.
A typical aggregate process may be arranged as:
Feeding → Primary Crushing → Secondary Impact Crushing → Screening → Finished Aggregate
For example:
Vibrating Feeder → Jaw Crusher → Impact Crusher → Vibrating Screen → Finished Products
Oversized material from the screen can be returned to the impact crusher to form a closed crushing circuit.
For construction waste recycling, the process may also include:
Feeding → Primary Crushing → Impact Crushing → Screening → Metal Removal → Recycled Aggregate
The complete process should be designed according to:
Impact crusher capacity and performance depend on feed size, material hardness, rotor configuration, discharge setting, and the complete crushing circuit.

Actual processing capacity may vary according to material characteristics, feed gradation, moisture, discharge requirements, and operating conditions.
The technical parameters should therefore be used for preliminary model selection rather than as guaranteed output under all conditions.
Impact crusher selection should be based on the material and complete crushing process rather than capacity alone.
For preliminary selection, please provide:
Important selection factors include:
Material Hardness and Abrasiveness
Impact crushers are best suited to medium-hard materials. Highly abrasive rock may increase blow bar and impact plate wear.
Feed Size
The maximum feed size should match the selected crusher model and upstream crushing stage.
Required Product Size
The final product size affects discharge adjustment, screening arrangement, and closed-circuit design.
Required Capacity
Capacity should be evaluated together with feed gradation, material characteristics, and the number of finished product specifications.
Wear Parts
Blow bars and impact plates are major wear components. Material abrasiveness and operating conditions should be considered when evaluating long-term operating cost.
Complete Crushing Circuit
The impact crusher should be selected together with the feeder, primary crusher, screen, conveyors, and return system.
LIPU Heavy Industry provides equipment for crushing, screening, grinding, classification, and mineral processing projects.
For impact crusher applications, LIPU can assist with:
For complete aggregate and mineral processing projects, the impact crusher can be selected as part of the entire crushing and screening line rather than as an isolated machine.
What materials are suitable for an impact crusher?
Impact crushers are commonly used for limestone, dolomite, sandstone, concrete, construction waste, gypsum, coal gangue, and other suitable medium-hard materials.
What is the difference between an impact crusher and a jaw crusher?
A jaw crusher mainly uses compression and is commonly used for primary crushing. An impact crusher uses high-speed impact force and is more commonly used for secondary crushing and product shaping.
Is an impact crusher suitable for hard rock?
It can process some hard materials, but highly abrasive rock may cause faster wear of blow bars and impact plates. A cone crusher may be more suitable for some hard and abrasive applications.
What determines impact crusher capacity?
Capacity depends on feed size, material hardness, feed gradation, rotor configuration, discharge setting, moisture, and the complete crushing circuit.
Can LIPU provide a complete impact crushing line?
