Impact crushers contain several wear components that perform different functions during material reduction.
Qirun provides replacement components for rotor striking surfaces and crushing chamber protection.
Blow bars are mounted on the crusher rotor and directly strike incoming feed materials.
As the rotor rotates, the blow bars accelerate and fracture the rock, sending material toward the impact plates for further crushing.
Blow bars are exposed to repeated impact and abrasion, making material selection and dimensional compatibility important.
Available Material Options:
CR26 High Chromium Alloy
CR27 High Chromium Alloy
CR27Mo2 High Chromium Alloy
Martensitic Steel
Selected Ceramic Composite Designs
Material selection depends on feed size, abrasiveness, impact intensity, and the risk of uncrushable material entering the crusher.
Impact plates, also called breaker plates or apron liners in certain crusher designs, form secondary crushing surfaces inside the chamber.
Rock accelerated by the blow bars strikes these surfaces and fractures into smaller particles.
Wear-resistant liners help protect the impact apron structure while maintaining the intended crushing geometry.
Key Characteristics:
Wear-resistant casting construction
Customized impact surface profiles
Replacement dimensions according to drawings
Material grades suited to operating conditions
Mounting configurations matched to the crusher
Side liners protect the interior side walls of the impact crusher from abrasive material contact.
They help reduce direct wear on the crusher housing during continuous operation.
Qirun supports replacement liner manufacturing according to customer drawings, dimensions, and mounting requirements.
Selected impact crushers use protective wear components around the rotor assembly.
These components help shield vulnerable rotor surfaces from abrasive particles and repeated material contact.
Replacement specifications must match the actual rotor design and equipment configuration.
High chromium alloys contain hard chromium carbides that provide resistance to abrasive wear.
CR26, CR27, and CR27Mo2 are material options for selected wear components operating in abrasive crushing environments.
High chrome materials are generally most suitable when feed size and severe impact risks are controlled.
Impact crusher applications vary significantly.
Some operations process abrasive natural stone, while others handle demolition materials or recycled aggregates.
Qirun provides different material options to accommodate requirements for hardness, toughness, and abrasion resistance.
Blow bars and liners must match the crusher's rotor, apron, or frame installation requirements.
Qirun supports replacement manufacturing based on original part numbers, customer drawings, and confirmed dimensional specifications.
Different impact crushers use different blow bar geometries and liner arrangements.
Available customization requirements may include:
Blow bar length, width, and height
Impact plate thickness and working profile
Mounting and contact surfaces
Liner dimensions and hole positions
Material specifications and heat treatment
Casting weight and machining requirements
Qirun provides wear-resistant casting and machining capabilities for mining machinery components.
Products can be manufactured according to customer-approved drawings and technical requirements.
Different alloys provide different combinations of hardness, toughness, and abrasion resistance.
Material | Main Advantage | Impact Tolerance | Typical Applications |
|---|---|---|---|
CR26 High Chrome | High Abrasion Resistance | Relatively Low | Abrasive aggregates and controlled-feed crushing |
CR27 High Chrome | High Hardness and Wear Resistance | Relatively Low | Selected abrasive crushing applications |
CR27Mo2 High Chrome | Alloyed Wear Resistance | Grade and Heat-Treatment Dependent | Demanding abrasion-related applications |
Martensitic Steel | Balance of Hardness and Toughness | Moderate to High, depending on grade | Mixed aggregate and selected recycling applications |
Ceramic Composite | Localized Abrasion Resistance | Matrix and Insert Dependent | Selected high-abrasion wear zones |
Tough Alloy Steel | Greater Impact Tolerance | Material Dependent | Applications requiring resistance to higher mechanical shock |
Exact material chemistry, hardness, and operating limits should be confirmed for each casting specification.
