1. فتحة مدفوعة بنقطة الألم

هل تعاني عملية التعامل مع فحم الكوك من اختناقات مستمرة؟, توليد الغرامات المفرطة, وتكاليف الصيانة غير المخطط لها? Inefficient screening directly impacts your plant’s bottom line through lost product, زيادة استهلاك الطاقة للعمليات النهائية, ووقت التوقف المكلف لاستبدال سطح الشاشة. Are you currently facing these challenges?
المسببة للعمى & تحمل أكثر: Moisture and sticky fines blind screen meshes, reducing effective screening area and forcing material to carry over unscreened, contaminating your product fractions.
ارتداء المفرط & صيانة: The abrasive nature of hot coke rapidly degrades standard screen panels and deck components, leading to frequent shutdowns for replacements and high spare parts inventories.
الانفصال غير الفعال: Inconsistent vibration or inadequate screening area results in poor size distribution control, sending offspec material to crushers or battery bunkers, disrupting the entire production chain.
التعب الهيكلي: The intense impact loads from coke discharge can cause premature failure of the screen body and support structures, risking major operational failure.

The right coke vibration screen is not just a separator; it’s a critical asset for throughput stability and product quality control.

2. نظرة عامة على المنتج

The heavyduty coke vibration screen is a highcapacity, linear motion screening machine engineered for the primary sizing and scalping of metallurgical coke. It is designed to withstand extreme abrasion, تأثير, and thermal stress in coke handling plants.

سير العمل التشغيلي:
1. يٌطعم & توزيع: Hot or cooled coke from a conveyor is discharged onto a robust feed box or plate, distributing the material evenly across the full width of the first screen deck.
2. Primary Stratification & التحجيم: The powerful dualvibrator motor drive generates a linear throwing motion. هذا الإجراء يطبق الطبقة المادية, forcing fines downward through the apertures of the upper deck(ق) while conveying oversize toward the discharge end.
3. Fraction Separation: مستويات سطح متعددة (عادة 2 أو 3) with precisely sized screen media (rails, سلك منسوج, أو ألواح البولي يوريثين) separate the coke into defined product streams (على سبيل المثال, فحم الكوك فرن الانفجار, فحم الكوك, نسيم).
4. تسريح: Sized fractions are discharged via separate chutes for transport to storage bunkers or downstream processes.

نطاق التطبيق & القيود:
نِطَاق: Ideal for primary screening of metallurgical coke after quenching or crushing; scalping of ovenrun coke; separation of coke breeze from larger fractions in byproduct recovery.
القيود: Not designed as a dewatering screen for slurries. Maximum feed temperature is determined by specific component selection (على سبيل المثال, heatresistant seals, motor isolators). قد تتطلب المواد اللزجة للغاية معالجة مسبقة أو أنظمة تنظيف متخصصة للسطح.

6. سيناريوهات التطبيق

مصنع الصلب المتكامل – إعداد تغذية الفرن العالي

تحدي: A major steel producer experienced rapid blinding of woven wire screens during humid conditions at their BF coke bunker station. This caused significant nut coke fraction carryover into blast furnace feed bins (~12%), disrupting burden permeability and increasing fuel rate.
حل: Implementation of two largecapacity linear motion screens fitted with nonblinding rod deck media on the upper decks for scalping oversize and openprofile polyurethane panels on lower decks for precise nut/breeze separation.
نتائج: Screening efficiency stabilized above 96%. Carryover was reduced to <3%. The plant reported an annual reduction in fuel rate attributed partly to improved burden control alongside a 65% drop in monthly screenrelated downtime.

Coke Plant – ByProduct Recovery Circuit

تحدي: A standalone coking plant needed to maximize recovery of saleable “nut” coke from its crushing circuit but struggled with excessive generation of undersize “breeze” due to aggressive screening action degrading fragile pieces.
حل:: Installation of a threedeck unit featuring adjustable stroke length via external counterweights on its vibrator motors was selected. This allowed operators finetune intensity based on feed characteristics..
نتائج: By optimizing stroke,,the plant increased yield within target nut size range (+8%) while reducing undersize generation (15%). The gentler handling also extended lowerdeck panel life by approximately 30%.
