سير العمل التشغيلي:

1. Feed Material Analysis – Beltmounted sensors measure moisture, توزيع حجم الجسيمات, and bulk density at 60second intervals
2. Crushing Stage Monitoring – Realtime power draw, CSS (إعداد الجانب المغلق), and cavity level data from primary jaw, مخروط ثانوي, and tertiary VSI crushers
3. Screening Efficiency Tracking – Vibration sensors and load cells on each deck calculate separation efficiency and blinding percentage
4. Product Quality Sampling – Automated crossbelt samplers collect specimens every 30 minutes for labgrade gradation testing
5. Adjustment Protocol – PLCbased control system automatically adjusts crusher settings, screen amplitude, and feed rate to maintain target specifications

نطاق التطبيق: Suitable for construction aggregate, قاعدة الطريق, الرمال الخرسانية, and asphalt mix production. Not designed for wet processing operations exceeding 8% feed moisture or materials with abrasion index above 0.8.
