For construction projects in Johannesburg, optimizing building costs per square meter requires high-efficiency sand and aggregate production. A well-designed crushing and sand-making line can reduce raw material expenses by 30-40%.
1. Primary Jaw Crusher: Processes raw granite/basalt (≤800mm) to ≤150mm
– Model example: JC98 (90-180t/h capacity)
2. Secondary Cone Crusher: Further reduces material to ≤40mm
– Hydraulic adjustment range: 6-38mm
3. Tertiary Impact Crusher: Produces cubic-shaped aggregates
– Rotor speed: 50-70m/s
4. Sand Maker (VSI): Final shaping for 0-5mm sand
– Throughput: 60-280t/h
| Equipment | Power(kW) | Max Feed(mm) | Output Size(mm) |
|---|---|---|---|
| Jaw Crusher | 110 | 800 | 150 |
| Cone Crusher | 160 | 235 | 40 |
| VSI Crusher | 250 | 50 | 5 |
– Midrand residential development (450t/day production)
– on commercial complex (using local quartzite)
– Roodepoort road construction project
Q: What’s the typical ROI period for such equipment?
A: 12-18 months when supplying major Johannesburg projects.
Q: How to control dust pollution?
A: Our systems include pulse dust collectors with ≥99% efficiency.
The right crushing configuration directly impacts your per-square-meter construction costs..
