1. فتحة مدفوعة بنقطة الألم

Managing consistent, highquality aggregate supply from quarry sites in Lagos is a persistent operational bottleneck. Are you facing these critical challenges?

Variable Feedstock Quality: Inconsistent rock hardness and contamination from laterite or clay directly impact crusher efficiency and final product specification, leading to rejected loads and contract penalties.
التوقف غير المخطط له: Equipment failure at the primary crushing stage due to uncrushable materials or excessive wear causes cascading delays, idling your entire processing line and haul fleet.
Inaccurate Yield Forecasting: Without realtime data on material hardness and size distribution, planning optimal crusher settings and maintenance windows is guesswork, تقليل الإنتاجية الإجمالية للمصنع.
Quality Control Lag Times: Waiting for lab results from sampled stockpiles means potentially shipping substandard material or failing to blend correctly, damaging your reputation with key clients in Lagos’s construction sector.

How can you gain realtime insight into your feed material to proactively protect your crushers, guarantee product specs, and optimize your entire production chain?

2. نظرة عامة على المنتج

The solution is an integrated onbelt analytical system for primary feed control. This industrial equipment provides continuous, noncontact elemental and material analysis of the raw feed on your primary conveyor.

سير العمل التشغيلي:
1. The system’s sensor is mounted above the conveyor carrying runofquarry material to the primary crusher.
2. As material passes underneath, it performs instantaneous elemental analysis (على سبيل المثال, detecting silica, الألومينا, الكالسيوم) and assesses material characteristics.
3. Data is transmitted to the plant’s control room software, which displays realtime composition and creates a compositional map of the feedstock.
4. Alerts can be configured to warn operators of harmful contaminants or significant grade changes.
5. This intelligence allows for proactive adjustments—such as minor feeder speed changes or initiating diversion—to protect downstream equipment and stabilize product quality.

نطاق التطبيق & القيود:
نِطَاق: مثالية للحجر الجيري, الجرانيت, and other aggregate quarries. Used for quality control of feed to primary crushers, grade control, and contaminant detection.
القيود: Requires consistent belt loading for optimal accuracy. Not a replacement for precise laboratory chemical analysis for final product certification but eliminates the delay for process control.
