1. فتحة مدفوعة بنقطة الألم

Is your coke processing operation struggling with persistent bottlenecks and escalating costs at the screening stage? تؤثر التحديات الشائعة في الشاشات التقليدية بشكل مباشر على أرباحك النهائية. هل تعاني:
المسببة للعمى & التوقف: Moisture and fine coke particles clog screen decks, تتطلب عمليات إيقاف تشغيل متكررة للتنظيف اليدوي, تكلف مئات ساعات الإنتاج سنويا.
Inconsistent Grading: Poor separation leads to offspec product (undersize in metallurgical coke, oversize in breeze), resulting in product rejection and revenue loss.
Excessive Maintenance: The abrasive nature of coke accelerates wear on screen panels and components, driving up spare parts costs and labor for replacements.
استهلاك عالي للطاقة: Inefficient vibration mechanisms and heavyduty designs lead to disproportionately high power usage per ton of material processed.
التعب الهيكلي: ثابت, highimpact loads from bulk coke can cause weld cracks and structural failures in the screen body, risking major unplanned downtime.

السؤال المركزي لمديري المصانع واضح: كيف يمكنك تحقيق موثوقة, continuous coke classification with lower operational expenditure and maximized equipment lifespan?

2. نظرة عامة على المنتج

تعتبر شاشة اهتزاز فحم الكوك الصينية من المهام الثقيلة, linear motion vibrating screen engineered specifically for the highvolume sizing and scalping of metallurgical coke, فحم الكوك البترولي, and foundry coke. It is designed to handle the unique abrasiveness, كثافة, and size ranges of bulk coke in processing plants.

سير العمل التشغيلي:
1. يٌطعم & توزيع: Bulk coke from crushers or ovens is fed onto the screen’s robust feed box, which evenly distributes material across the full width of the screening surface.
2. التقسيم الطبقي الفعال & الانفصال: Dual vibrator motors generate a linear throwing motion, stratifying material rapidly. Coke particles smaller than the screen panel apertures pass through as undersize product.
3. تسريح: Correctly sized oversize material travels along the deck length and discharges at the end, while undersize material collects in a hopper below.

نطاق التطبيق: التحجيم الأساسي (سلخ فروة الرأس) من فحم الكوك, secondary screening of crushed coke (على سبيل المثال, 2540mm blast furnace coke), إزالة الغبار (إزالة نسيم فحم الكوك), and dewatering applications.

القيود: Not designed for extremely sticky materials without specialized deck treatments. Maximum lump size is typically limited to 200mm; alternative solutions are required for larger primary runofmine scalping.

6. سيناريوهات التطبيق

Metallurgical Coke Plant – Blast Furnace Feed Preparation

Challenge A major steel plant faced frequent blinding on traditional screens during humid months, causing a ~20% drop in throughput for their critical +25mm BF coke fraction and generating excessive 10mm fines.
Solution Installation of twotier China Coke Vibration Screens equipped with nonblinding polyurethane panels featuring tapered apertures.
Results Screening efficiency stabilized at ≥94%. Annual production of onspec (+25مم) coke increased by an estimated 75,000 طن. Maintenance downtime for screen cleaning was reduced by over 400 hours per year.

Petroleum Coke Calcining Plant – Green Coke Scalping

Challenge A calciner needed reliable precalcination scalping of green petroleum coke at high temperatures (~150°C feed) to remove sub2” fractions before kiln entry. Existing screens suffered rapid thermal warping and bearing failures.
Solution Deployment of hightemperature adapted China Coke Vibration Screens featuring heatresistant seals on bearings and thermally stable deck components.
Results The solution provided continuous operation at elevated temperatures without performance degradation. Bearing service life extended from under six months to over two years between changes.
