Impact Crusher Side Liners
Chrome White Iron, Alloy Steel & Bimetallic Wear Liners
Heavy-duty side liners designed to protect impact crusher housings from abrasion and wear. Available in chrome white iron cast liners, alloy steel cut liners, and chrome-brazed bimetallic liners for extended service life in demanding crushing environments.
What Impact Crusher Side Liners Do and Why They Matter
Side liners are protective wear plates installed along the internal housing walls of horizontal shaft impact (HSI) crushers. During crushing, material accelerated by the rotor and blow bars moves rapidly through the chamber and continuously impacts or slides along the crusher housing. Side liners protect the main crusher structure from this abrasion and impact, preventing damage to the housing and extending the service life of the machine.Without side liners, the structural steel housing of the crusher would wear quickly under the constant flow of abrasive material. By acting as sacrificial wear components, side liners absorb the majority of this wear and can be replaced periodically without affecting the crusher frame.
Side liner wear patterns vary depending on the material flow path and chamber position. Areas close to the rotor discharge or high-velocity material streams typically experience significantly higher abrasion than zones near the feed opening. For this reason, side liners are manufactured in different materials such as chrome white iron, alloy steel, or bimetallic liners to match specific wear conditions. Selecting the correct liner material helps reduce maintenance frequency, improve crusher availability, and lower total wear part cost. Our engineering team can recommend the most suitable side liner solution based on your crusher model, feed material characteristics, and operating conditions.

Side Liners Maintenance Guide
Proper inspection and maintenance of side liners help protect crusher housings and extend equipment service life.
- Regular Wear Inspection
Inspect side liners regularly for excessive wear, cracks, or deformation. Early detection helps prevent damage to the crusher housing and other wear components. - Monitor Liner Thickness
Measure liner thickness during scheduled maintenance shutdowns. Replace liners before wear reaches the minimum safe thickness to maintain proper housing protection. - Check Mounting Bolts and Fasteners
Ensure mounting bolts and fixing hardware remain securely tightened. Loose liners can cause abnormal wear patterns and damage to the crusher housing. - Observe Wear Distribution
Uneven wear across side liners may indicate incorrect material flow or improper crusher settings. Adjust feed distribution to improve liner life. - Replace Liners Before Housing Exposure
Side liners act as sacrificial wear plates protecting the crusher housing. Replace liners before wear reaches the base structure to avoid costly repairs.
Inspection Before Rotation
Always inspect blow bars for cracks before rotation or flipping.
Cracked blow bars should be replaced instead of reused, as cracks may propagate under impact and lead to unexpected failure.
Also check mounting holes and fasteners for elongation, wear or damage.

Side Liners FAQs
Find answers to common questions about impact crusher side liners, liner materials, wear life, and replacement recommendations.
How often should impact crusher side liners be replaced?
The replacement interval for side liners depends on feed material abrasiveness, crusher operating conditions, and liner material type. High-wear zones near the rotor discharge typically require more frequent replacement than areas near the feed opening. In most aggregate and quarry applications, side liners may last several blow bar change cycles before replacement is required. Regular inspection and thickness monitoring are recommended to determine the optimal replacement timing.
What is the minimum acceptable liner thickness?
Side liners should be replaced before wear reaches the base structure of the crusher housing. As a general guideline, replacement is recommended when the remaining liner thickness reaches approximately 25–30% of the original thickness. Operating liners beyond this limit may expose the crusher housing to excessive wear and increase the risk of structural damage.
Can different liner materials be used in different crusher positions?
Yes. Different areas inside an impact crusher experience different wear conditions. High-impact zones may benefit from manganese steel liners, while abrasion-dominated areas are better suited to chrome white iron or bimetallic liners. Selecting the correct liner material for each position can significantly improve wear life and reduce overall maintenance costs.
Can worn side liners be rebuilt or repaired?
In some cases, liners made from steel plate materials can be repaired using hardfacing or overlay welding. However, heavily worn or cracked liners should be replaced to ensure proper crusher protection and safe operation. For high-chrome or bimetallic liners, replacement is typically recommended once wear reaches the specified limit.
How do side liners protect the crusher housing?
Side liners act as sacrificial wear plates that protect the internal housing walls of the impact crusher. During crushing, material moving through the chamber creates continuous abrasion and impact against the crusher structure. By absorbing this wear, side liners prevent damage to the main crusher frame and can be replaced periodically as part of normal maintenance.
