Project Background 4-Seam & 5-Seam Plant Chutes in the Plant Liners on Chutes
Wear liner on chutes Wear liner is a material used on the interior of a chute as a sacrificial surface. It serves as an easily replaceable sacrificial wear surface to protect the walls of the chute.
Materials used on chutes Mild steel (Chutes) -Low maintenance -Price is relatively low -It is neither brittle or Ductile -Corrosion resistance Stainless Steel  (Liner material) - Abrasion resistance - Antibacterial - Passivation - High strength - Corrosion resistance
Liner results Greater Savings associated with using Polyurethane Installation & maintenance is very cheap 6 Times lighter Therefore very safe to work with Lasts longer than stainless steel Great reduction in noise levels Decrease in downtime
Functions of an effective chute To feed the receiving conveyor in its direction of travel To centralize the material load
Functions of an effective chute To minimize the impact on the receiving belt and material degradation - Chute angles - Material buffer Grizzly Bars installed on Chutes
Functions of an effective chute To supply the stream of material at a speed as close as possible to the speed of the receiving conveyor. To minimize the generation of spillage and the release dust.
Functions of an effective chute Traditional chutes
