Targeting Sustainable Quarry Operations in Lagos: HighEfficiency Mobile Crushing & Screening Plants

1. فتحة مدفوعة بنقطة الألم

Operating a quarry site in Lagos presents distinct challenges that directly impact profitability and operational viability. Are you managing:
Escalating Operational Costs: Unpredictable fuel consumption from inefficient, aging equipment and the high expense of transporting raw material to a fixed processing site.
عدم مرونة الموقع & التوقف: Significant revenue loss when primary crushers are down for maintenance, or when you need to relocate processing to follow aggregate seams, resulting in days of nonproduction.
Strict Environmental & Community Constraints: Pressure to minimize dust, ضوضاء, and land footprint within Lagos’s rapidly developing periurban areas, alongside the need for rapid site rehabilitation.
Inconsistent Aggregate Quality: Difficulty in meeting precise grading specifications for concrete and road base due to outdated screening technology, leading to product rejection or reduced market value.
High Logistics Complexity: Coordinating multiple machines (excavator, primary crusher, شاشة, الناقلات) that are not designed as an integrated system, creating bottlenecks and management overhead.

How do you increase yield and reduce costperton while adhering to stricter environmental standards and maintaining operational flexibility?

2. نظرة عامة على المنتج

Our solution is a trackmounted Mobile Crushing and Screening Plant engineered for sustainable quarrying. This integrated system moves directly to the rock face, eliminating dump trucks between the excavation point and primary crushing.

سير العمل التشغيلي:
1. Direct Face Feeding: An excavator loads blasted rock directly into the mobile plant's hopper at the quarry face.
2. OnSite Size Reduction: The material undergoes primary and often secondary crushing directly on the tracks.
3. Precise Sorting: Integrated highcapacity screens separate crushed material into precisely graded fractions (على سبيل المثال, 05مم, 510مم, 1020مم).
4. التخزين & النقل: Finished aggregates are conveyed to designated stockpiles. The entire plant can be relocated under its own power in under 30 دقائق.

نطاق التطبيق: Ideal for mediumtolarge scale granite, الحجر الجيري, or laterite quarry operations requiring multiple aggregate products. Suitable for greenfield sites and established pits where moving processing points is necessary.

القيود: Not designed for ultrahard abrasive ores without specific liner configurations. Maximum singlefeed size is determined by plant model; oversize boulders may require prebreaking.
