1. فتحة مدفوعة بنقطة الألم

Is your coke handling operation plagued by persistent inefficiency and hidden costs? لمديري المصانع والمقاولين الهندسيين, the screening phase is a critical bottleneck with direct consequences for profitability. وتشمل التحديات المشتركة:

توليد الغرامات المفرطة: Inefficient screening leads to overbreaking of coke, converting valuable product into lowvalue fines. This represents a direct loss of revenue per ton.
انسداد الشاشة المتكرر & التوقف: Sticky coke particles and moisture cause blinding, تتطلب عمليات إيقاف تشغيل متكررة للتنظيف اليدوي. يؤدي هذا التوقف غير المخطط له إلى إيقاف خط المعالجة بالكامل.
تصنيف المنتج غير متناسق: An unreliable screen fails to deliver precise size separation, compromising the quality specifications demanded by your blast furnace or foundry customers, risking contract compliance.
صيانة عالية & تكاليف الاستبدال: Vibrating screens that are not engineered for the abrasive nature of coke suffer rapid wear on decks, الينابيع, والمثيرين, مما يؤدي إلى ارتفاع استهلاك قطع الغيار وتكاليف العمالة.

Are you ready to reduce your costperton, increase plant availability, and ensure a consistently onspec product? The solution lies in specifying a purposebuilt شاشة اهتزاز فحم الكوك.

2. نظرة عامة على المنتج

أ شاشة اهتزاز فحم الكوك is a heavyduty industrial screening machine designed for the dry separation of metallurgical coke into precise size fractions after crushing. Its core function is to ensure only correctly sized coke proceeds to blast furnace charging or shipment.

سير العمل التشغيلي:
1. مقدمة الأعلاف: Crushed coke is uniformly fed onto the inclined screen deck(ق) via a feed box or chute.
2. الفصل الاهتزازي: كثافة عالية, linear or circular vibration stratifies the material. Smaller particles pass through the screen media apertures (أقل من الحجم), while larger particles travel across the deck surface (كبيرة الحجم).
3. Product Diversion: Separated fractions are discharged via distinct chutes—typically into oversize (return for recrush), حجم المنتج, and fines hoppers.

نطاق التطبيق: Primary sizing of metallurgical coke in coke plants, مصانع الصلب, ومحطات المناولة السائبة. Suitable for hot or cold coke screening.

القيود الرئيسية: Not designed for wet screening processes or for materials with extreme adhesive properties without specialized deck treatments.
