1. فتحة مدفوعة بنقطة الألم

Is your coke handling operation plagued by persistent bottlenecks and quality control issues? لمديري المصانع المشرفين على فحص فحم الكوك, تؤثر التحديات المشتركة بشكل مباشر على الإنتاجية والربحية. يمكن أن يؤدي تلوث الغرامات المفرطة في تدفقات المنتج إلى رفض العملاء وخسارة الإيرادات. كثرة القماش الشاشة المسببة للعمى من لزجة, highmoisture coke drastically reduces effective screening area, forcing premature shutdowns for manual cleaning. The constant impact abrasion from bulk coke leads to rapid wear of screen decks and components, generating high replacement part costs and unplanned maintenance windows. Vibration isolation failures transfer destructive forces to support structures, creating longterm integrity concerns and safety risks. How do you maintain specified size fractions consistently while extending equipment service life and maximizing plant uptime? The efficiency of your downstream blast furnace or smelting operation depends on the reliability of this critical separation stage.

2. نظرة عامة على المنتج

The Coke Vibration Screen is a heavyduty, highamplitude screening machine engineered for the scalping and precise size classification of metallurgical coke, فحم الكوك البترولي, and foundry coke. Its design prioritizes durability and material throughput in harsh, abrasive environments.

سير العمل التشغيلي:
1. يٌطعم & توزيع: Bulk coke is fed onto the robust feed box, الذي يوزع المادة بالتساوي عبر العرض الكامل لسطح الشاشة الأساسي.
2. HighEnergy Separation: The exciter drive generates a powerful linear or elliptical motion, aggressively conveying coke along the deck while forcing undersized particles through the screen apertures.
3. Fractional Discharge: المنتج ذو الحجم الصحيح (كبيرة الحجم) discharges from the deck's end, while fines (أقل من الحجم) pass through to a lower collection chute or subsequent deck for further grading.

نطاق التطبيق: التحجيم الأساسي لفحم الكوك المفرغ من الفرن, إزالة نسيم (الغرامات) from blast furnace feed, classification of recirculated coke in sinter plants, وتطبيقات إزالة الغبار.

القيود: Not designed for ultrafine screening (8%) may require predrying or heated deck options.
