Food Grade Polyurethane Chute Liners

Flotation machines wear their parts quickly. Our Flotation Wear Parts are essential spares for flotation equipment, including impeller covers, stators, rotors, and wear liners. These parts contact slurry and bubbles directly, enduring high-speed rotation and corrosion.

Cushions impact between grain and metal walls
Reduces grain breakage by 50%–80%
Prevents metal contamination
Ideal for grain storage, flour mills, feed mills, and port loading lines
