For construction projects requiring budget-friendly raw materials, recycled tiles from Durban’s secondhand market can be crushed into high-quality sand and aggregates. A tailored crushing-screening line transforms these discarded tiles into reusable resources.
1. Jaw Crusher (Primary Crushing)
– Model: PE-400×600
– Feed Size: ≤340mm
– Capacity: 16–64t/h
– Power: 30kW
2. Impact Crusher (Secondary Crushing)
– Model: PF-1214
– Rotor Diameter: 1250×1400mm
– Capacity: 70–130t/h
– Power: 132kW
3. Vibrating Screen
– Layer: 2–3 decks
– Mesh Size: 3–50mm (adjustable)
| Product | Grain Size (mm) | Application |
|—————-|—————–|—————————|
| Coarse Sand | 2.5–5 | Concrete mixing |
| Fine Sand | 0.15–2.5 | Mortar, plaster |
| Gravel | 5–20 | Road base, drainage |
Q1: Can recycled tile sand replace natural sand?
Yes, after proper grading and impurity removal, it meets ASTM C33 standards for non-structural concrete.
Q2: What’s the production cost per ton?
Approximately $8–12/ton, including power and labor (Durban rates).
Durban Urban Renewal Initiative (2023)
– Material Source: Demolished ceramic tiles from residential buildings.
– Output: 120t/day of mixed sand/gravel for sidewalk paving.
– Equipment Used: PE-400×600 + PF-1214 + 3YK1860 screen.
This setup demonstrates how secondhand tiles can be repurposed efficiently, reducing landfill waste and material costs simultaneously.
