Material Spillage Reduction – Slashing Waste by 50%
Project Objective:
Reduce material spillage, improve process standardization, and lower annual financial losses in grinding operations.
Executive Summary
A detailed analysis of grinding operations identified chronic material spillage caused by tray design issues, worn seals, inconsistent operating practices, and lack of visual controls. Through engineering modifications, process hardening, and SOP standardization, the organization achieved a 58% reduction in spillage and significantly reduced annual losses.
Baseline Situation
| Metric | Baseline Performance |
|---|---|
| Average Monthly Spillage | 502 Kg |
| Total Recorded Loss | 6,520 Kg |
| Number of Incidents | 13 |
| Average Night Shift Spillage | 1.3 Kg |
Root Cause Analysis
| Issue | Impact | Root Cause |
|---|---|---|
| Tray Gaps | Material Leakage | Poor tray design |
| Worn Seals | Continuous Losses | Equipment deterioration |
