Georgia hosts numerous rock quarries producing granite, limestone, and basalt for construction aggregates. Key quarry regions include Elberton (granite), Columbus (marble), and Macon (limestone). Efficient crushing and sand-making lines are critical for transforming raw stone into high-quality aggregates.
A typical crushing-sand production line includes:
1. Primary Jaw Crusher: Breaks large rocks (<800mm) into smaller pieces (150–300mm). Example model: PE-600×900 (Capacity: 50–160 t/h).
2. Secondary Cone Crusher: Further crushes material to 20–70mm. Model example: HP300 (Capacity: 120–200 t/h).
3. Tertiary Impact Crusher/VSI Sand Maker: Produces 0–5mm sand or cubic-shaped aggregates. Model: VSI-1140 (Capacity: 60–180 t/h).
| Equipment | Model | Feed Size | Output Size | Capacity (t/h) |
|---|---|---|---|---|
| Jaw Crusher | PE-600×900 | ≤500mm | 65–160mm | 50–160 |
| Cone Crusher | HP300 | ≤230mm | 10–40mm | 120–200 |
| VSI Crusher | VSI-1140 | ≤50mm | 0–5mm sand | 60–180 |
Screens (e.g., 3YK3070 vibrating screen) separate aggregates by size, while sand washers remove impurities. A closed-loop water recycling system minimizes environmental impact.
Q1: What’s the ideal crusher for granite?
A: A jaw + cone + VSI combo ensures high yield with low flakiness.
