Its core is suitable for bulk material conveying and storage applications involving high impact, severe wear, and the need to prevent clogging.
Key Application Scenarios
- Heavy-duty silo and hopper linings: Impact zones for large ore or coal drops; ribbed structures help distribute impact forces and prevent material adhesion and buildup.
- Transfer chutes and feed hoppers: High-frequency impact wear areas in power plant coal handling systems, steel sintering plants, cement plant discharge chutes, etc.
- Feed ends of crushers and feeder channels: Conditions involving direct impact from raw ore, requiring both high wear resistance and fracture toughness.
- Port stacking, reclaiming, and bulk cargo handling equipment: Continuous impact wear protection under high throughput conditions.
Structural Features and Functional Logic
These liners typically feature a composite structure of steel–rubber–ceramic, with "AR bars" often consisting of surface-protruding ceramic ribs or metal reinforcing ribs:
Wear-resistant layer: High-alumina ceramic blocks provide the fundamental wear resistance.
Buffer layer: The intermediate rubber layer absorbs the impact energy from falling bulk materials, preventing ceramic breakage.
Rib function: The raised structure alters the flow path of materials, reducing direct impact wear, while also offering self-cleaning and anti-clogging properties to prevent fine powder agglomeration.
