Media Life Cycle Analysis
Durability, Recyclability & Total Cost of Ownership
1. Introduction to Media Lifecycle
Media life cycle analysis evaluates the complete operational lifespan of abrasive media from initial deployment through final disposal. Understanding media lifecycle is crucial for optimizing blasting operations, reducing costs, and minimizing environmental impact.
Lifecycle Cost Factors
Media cost per kg (varies by type)
Recycle cycles achievable
Cost savings through recycling
2. Lifecycle Stages
1. Initial Deployment
Fresh media is loaded into the blasting system. Initial performance characteristics are established.
2. Active Service
Media undergoes repeated impact cycles, gradually losing effectiveness through fragmentation and contamination.
3. Recycling & Reclamation
Used media is collected, cleaned, and separated for reuse. Quality control ensures consistent performance.
4. End of Life
Media is depleted beyond economical recycling. Disposal or alternative use is determined.
3. Total Cost of Ownership (TCO)
TCO Formula
TCO = (M₀ + ΣMᵢ + L + E + D) / A| Media Type | Initial Cost | Cycles | TCO/m² | Cost Efficiency |
|---|---|---|---|---|
| Steel Shot | $1,200 | 100+ | $2.50 | Excellent |
| Garnet | $400 | 5-10 | $4.20 | Good |
| Aluminum Oxide | $1,800 | 20-30 | $3.80 | Good |
| Glass Beads | $800 | 1-3 | $8.50 | Average |
