1. فتحة مدفوعة بنقطة الألم

هل تعاني عملية فحص فحم الكوك من استمرارية العمل؟, أوجه القصور المكلفة? لمديري المصانع والمقاولين الهندسيين, the vibration screen is a critical yet vulnerable point in the material handling chain. وتشمل التحديات المشتركة:

التوقف المفرط: Premature screen deck failure and bearing seizures due to coke abrasiveness and high temperatures, leading to unplanned maintenance stops that cost thousands per hour in lost production.
Poor Separation Efficiency: Inconsistent sizing of metallurgical coke or petroleum coke, resulting in offspec product that fails to meet blast furnace or anode grade requirements, directly impacting your revenue and customer contracts.
تكاليف صيانة عالية: The constant battle against wear on screen panels, لوحات جانبية, and exciters creates a relentless cycle of parts replacement and labor expenditure.
Structural Integrity Risks: Fatigue cracks in the screen body from relentless, highcycle loading threaten catastrophic failure, posing safety risks and requiring major capital repair.

Are you searching for a vibration screen engineered not just to handle coke, but to withstand its punishing demands while protecting your bottom line?

2. نظرة عامة على المنتج: شاشة اهتزاز فحم الكوك الثقيلة

This equipment is a specifically engineered linear motion or elliptical motion vibrating screen for the classification and sizing of hot or cold metallurgical coke and petroleum coke (المكلس أو الأخضر). تصميمه يعطي الأولوية للمتانة, وقت التشغيل, and precise separation under severe operating conditions.

سير العمل التشغيلي:
1. يٌطعم & توزيع: Bulk coke from the crusher or oven is evenly distributed across the full width of the feed deck via an integral feed box.
2. التقسيم الطبقي & التحجيم: Controlled vibratory motion stratifies material by size; undersize particles pass through precisely sized screen panel apertures.
3. Material Conveyance: Larger particles travel along the deck length for discharge as oversize product.
4. فصل المنتج: Properly sized fractions are collected via sealed discharge spouts for downstream processing or shipment.

نطاق التطبيق: Primary and secondary screening of metallurgical coke (فحم الكوك فرن الانفجار), فحم الكوك البترولي (anode grade, fuel grade), recarburizers. Suitable for hot screening applications postquenching (with appropriate material specs).
القيود: Not designed for wet screening processes or as a replacement for scalping screens handling extremely large (+300مم) feed with high impact loads without prior modification.
