The Abu Tartur phosphate deposit in Egypt is one of the largest globally, requiring efficient grinding solutions to produce high-quality sand and aggregates. A tailored crushing and grinding line ensures optimal particle size distribution for downstream processing.
1. Primary Jaw Crusher (e.g., JC5460)
– Capacity: 800–1,200 t/h
– Feed Size: ≤1,500 mm
– Output: 150–300 mm
2. Secondary Cone Crusher (e.g., HPT500)
– Capacity: 500–800 t/h
– Closed Side Setting (CSS): 20–50 mm
3. Tertiary Impact Crusher/VSI (e.g., B9100SE)
– Capacity: 300–600 t/h
– Output Fineness: 0–5 mm (adjustable)
4. Ball Mill/Vertical Roller Mill (e.g., Ф5×15m Ball Mill)
– Grinding Fineness: 80% passing 200 mesh
| Product | Size Range (mm) | Moisture (%) | Application |
|—————-|—————–|————–|—————————|
| Coarse Sand | 0.5–2.5 | ≤3 | Construction aggregates |
| Fine Sand | 0.075–0.5 | ≤4 | Phosphoric acid production |
Q1: How to reduce overgrinding in phosphate rock processing?
A: Optimize crusher CSS and use multi-stage screening to bypass fines.
Q2: What wear parts require frequent replacement?
A: VSI rotor tips and cone crusher mantles typically last 600–800 hours in abrasive phosphate rock.
A project in Abu Tartur deployed a three-stage crushing + ball mill circuit, achieving 95% yield for sand meeting ISO 14688 standards. Dust suppression systems reduced airborne particles by 70%.
