Lagos Industrial Zone Plant
– Raw material: Gray limestone (CaCO₃ content ≥85%)
– Final products:
0-5mm sand (concrete grade),
5-20mm aggregate (asphalt mix),
20-40mm road base
Q1: What’s the moisture tolerance for feeding?
*A:* Recommended <10%. Wet material requires pre-screening.
Q2: How to control dust pollution?
*A:* Water spray systems + bag filters reduce dust to <30mg/m³.
Q3: Maintenance interval for wear parts?
*A:* Jaw plates: ~6 months; Cone liners: ~8 months (varies by abrasiveness).
This turnkey solution achieves 85%+ operational rate with proper maintenance, meeting Nigeria’s
