1. Addressing Critical Screening Challenges in Coke Handling

Is your coke screening operation a source of consistent cost overruns and production bottlenecks? Inefficient particle separation directly impacts blast furnace efficiency, جودة المنتج, وميزانيات الصيانة. وتشمل التحديات الرئيسية:
Blindness & انسداد: Adhesive coke fines and moisture cause rapid screen mesh blinding, تتطلب عمليات إيقاف تشغيل متكررة للتنظيف اليدوي. This can result in 1530% downtime on a single line.
ارتداء المفرط & صيانة: The abrasive nature of metallurgical coke accelerates wear on screen decks, الينابيع, وآليات الاهتزاز, leading to high parts replacement costs and unpredictable failures.
توزيع حجم غير متناسق: Poor separation allows undersize fines into the blast furnace feed or oversize material into the byproduct stream, disrupting furnace permeability and reducing yield.
التعب الهيكلي & نقل الاهتزاز: High Gforces needed for effective coke screening can damage support structures and transmit harmful vibrations to adjacent equipment.

Are you evaluating screening solutions that offer higher availability, تكلفة أقل, and precise grading to protect downstream processes?

2. نظرة عامة على المنتج: HeavyDuty Coke Vibration Screens

أ شاشة اهتزاز فحم الكوك هي قدرة عالية, bruteforce separator designed for the rigorous dry or slightly damp screening of metallurgical coke. Its primary function is to ensure a consistent, specificationgrade feed for blast furnaces while removing undersize coke breeze for other uses.

سير العمل التشغيلي:
1. مقدمة الأعلاف: Runofoven (ROO) coke is uniformly distributed onto the inlet end of the inclined screen deck.
2. الفصل الاهتزازي: An eccentric vibrator assembly imparts a linear or elliptical throwing motion, stratifying material and propelling it along the deck.
3. فصل الحجم: Particles smaller than the screen aperture fall through as undersize (نسيم فحم الكوك), while larger particles travel across the deck as productsized coke.
4. تسريح: Correctly sized coke discharges at the deck end for furnace charging; undersize material is collected separately.

نطاق التطبيق: التحجيم الأولي لفحم الكوك المعدني (typically 25mm80mm fractions), scalping of oven discharge material, and recovery of coke from slag. Not recommended for wet screening or extremely sticky materials without specialized deck technology.

6.سيناريوهات التطبيق

مصنع الصلب المتكامل – إعداد تغذية الفرن العالي

تحدي: A major mill experienced frequent blinding on its primary coke screens during humid months. This caused backfeeding onto conveyors and inconsistent size feed (<25mm fines exceeding spec), disrupting blast furnace stability. Manual cleaning was required every two shifts.
حل: Installation of a new heavyduty Coke Vibration Screen featuring a polyurethane balltray antiblinding system and variablespeed drives.
نتائج: Screen blinding was eliminated entirely between scheduled monthly inspections. The ability to adjust vibration parameters ensured consistent sizing yearround, resulting in a measured <2% oversize/undersize fraction. Furnace permeability improved by an estimated 8%.

Merchant Coke Producer – Byproduct Revenue Optimization

تحدي: The client’s existing screens allowed excessive productsized coke (25مم+) into the breeze stream sold as lowvalue fuel. This represented a significant loss of premium product revenue.
حل: Retrofitting their screening station with precision Coke Vibration Screens featuring multideck configurations for tighter cutpoint control.
نتائج: A postinstallation audit showed a reduction in misplaced product from ~12% to under 3%. This recovery added approximately $180k annually in recaptured revenue at prevailing market prices.
