Abrasion-Resistant Lining: Thickness 10-50 mm, Hardness ≥58 HRC

Component Specifications

Definition

A specialized protective component installed inside rotary granulation drums to shield the drum surface from abrasive wear caused by continuous material processing. It consists of high-hardness plates or segments that absorb impact and friction, maintaining drum integrity and preventing material contamination.

Working Principle

Works by providing a sacrificial wear surface that absorbs the abrasive forces from processed materials (e.g., fertilizers, chemicals, minerals) during granulation. The lining distributes impact energy, reduces friction between materials and drum walls, and prevents direct contact that would cause rapid deterioration of the base metal.

Materials

High-chromium cast iron (Cr15-Cr27), ceramic-alumina composites, or hardened steel alloys (AR400-AR500). Surface hardness typically 58-65 HRC.

Frequently Asked Questions

How often should abrasion-resistant lining be replaced?

Replacement intervals depend on material abrasiveness and operating conditions, typically ranging from 12-36 months with proper maintenance.

Can different lining materials be combined in one drum?

Yes, strategic combination of materials (e.g., ceramic in high-wear zones, steel in impact areas) can optimize performance and cost-effectiveness.
