Lean Implementation of Screw Conveyors: Efficiency Revolution and Quality Enhancement in a Feed Production Line

During expansion, a major feed manufacturer faced multiple challenges including low production efficiency, severe dust pollution, and cross-contamination of materials. To overcome these bottlenecks, the company implemented a new enclosed automated conveying system centered around screw conveyors.

Horizontal Conveying: U-shaped trough screw conveyors were selected for primary ingredient transport. Their enclosed structure completely prevents dust leakage, operates smoothly, and ensures precise subsequent ingredient blending.

Vertical Conveying: Vertical screw conveyors elevate finished pellet feed into storage silos. These compact units maximize vertical space utilization and deliver high lifting efficiency.

Precision Conveying: For trace premixes prone to residue buildup, shaftless screw conveyors were deployed. Their unique shaftless design prevents material entanglement and residue accumulation, significantly reducing cross-contamination risks.

Following system implementation, notable improvements were achieved:

Efficiency Enhancement: Continuous automated conveying increased production efficiency by approximately 30%.

Quality Enhancement: Enclosed conveying eliminates contamination, ensuring consistent product quality.

Cost Reduction: Reduced labor and material losses with simplified equipment maintenance.

Safety and Environmental Protection: Substantially lowered dust concentration in the work environment, eliminating safety hazards.

This case study demonstrates how the flexible application of different screw conveyor types successfully resolved critical bottlenecks in feed production, fully validating their core value in achieving modern, automated, and clean production.
