Flow Liner

A flow liner is a specialized industrial component designed as an internal lining for collection chutes, hoppers, and transfer points in material handling systems. It serves as a sacrificial wear surface that protects the primary structure from abrasion, impact, and corrosion while ensuring smooth, consistent material flow without bridging, rat-holing, or segregation. Typically manufactured as modular plates or custom-shaped sections, flow liners are engineered to match specific material characteristics and flow patterns, with optimized surface properties to reduce friction and buildup. They are critical for maintaining system efficiency, reducing maintenance downtime, and extending equipment lifespan in continuous processing operations.

The flow liner operates on principles of tribology and material science to manage interfacial interactions between flowing materials and equipment surfaces. By providing a low-friction, wear-resistant barrier, it minimizes adhesion and mechanical resistance, allowing materials to slide smoothly under gravity or mechanical force. The liner's geometry and surface texture are designed to match material flow angles (such as angle of repose and slide angles) to prevent stagnation points. It functions as a sacrificial element that absorbs kinetic energy from impacting particles, protecting the underlying structure from degradation while maintaining consistent cross-sectional flow area to prevent flow restrictions.
