1. فتحة مدفوعة بنقطة الألم

Is your coke processing line plagued by persistent bottlenecks and escalating operational costs? لمديري المصانع والمقاولين الهندسيين, the screening phase is often a critical failure point. وتشمل التحديات المشتركة:

المسببة للعمى & Poor Separation: Fine, moist coke particles adhere to screen decks, causing rapid blinding. This forces either frequent manual cleaning or the acceptance of contaminated product streams, directly impacting product quality and saleable tonnage.
التوقف المفرط للصيانة: Conventional screens require frequent shutdowns for screen cloth changes and bearing inspections. This unplanned downtime halts your entire processing line, تكلف الآلاف في الساعة من الإنتاج المفقود.
استهلاك عالي للطاقة & الإجهاد الهيكلي: Inefficient vibratory motion translates to wasted electrical power. بالإضافة إلى, unbalanced forces can cause premature fatigue and cracking in the screen body and support structure, leading to catastrophic failures.
Inconsistent Grade Control: Inability to maintain precise cut points results in offspec material—either oversized contaminants in the final product or valuable onspec coke reporting to waste.

Are you searching for a screening solution that delivers sustained throughput, minimizes unscheduled stops, and protects your profit margins? The right industrial vibration screen is not just a piece of equipment; it is a strategic investment in plant reliability.

2. نظرة عامة على المنتج

تتميز شاشة اهتزاز فحم الكوك شديدة التحمل بقدرة عالية, linear motion screening machine engineered for the rigorous dry or slightly moist separation of metallurgical coke and petroleum coke. It is designed to handle abrasive materials at high temperatures with continuous 24/7 عملية.

سير العمل التشغيلي:
1. يٌطعم & توزيع: Sized coke from crushers or ovens is evenly distributed across the full width of the screen's feed box.
2. التقسيم الطبقي & الانفصال: Twin counterrotating vibratory motors generate a linear throwing motion, stratifying material. Smaller particles pass through precisely sized screen panel apertures.
3. تسريح: Correctly sized fractions are discharged via separate chutes—typically oversize (for recrushing), حجم المنتج, والغرامات.

نطاق التطبيق: التحجيم الأساسي (سلخ فروة الرأس) and final grade separation of coke ranging from lump (على سبيل المثال, +50مم) to nut coke (على سبيل المثال, 1025مم). Suitable for sinter plants, blast furnace charging systems, and anodegrade coke preparation.

القيود: Not designed for wet washing applications or for materials with extreme adhesive properties without specialized screen media.

6. سيناريوهات التطبيق

[Steel Mill Blast Furnace Feed] تحدي: A major integrated steel mill experienced frequent blinding on its final coke screens before skip charging, causing oversized material (+80مم) to enter the furnace burden at rates exceeding plant specifications (>3%). This disrupted furnace permeability.

[حل]: Implementation of a tripledeck Coke Vibration Screen equipped with nonblinding rubber screen panels on the top deck for effective scalp removal of oversized pieces.

[نتائج]: Oversize contamination reduced consistently below <0.8%. Annualized reduction in fuel rate attributed partly to improved burden distribution was measured at approximately ~1%.

[Petroleum Coke Calcining Plant] تحدي: An anodegrade calciner needed precise separation of calcined petroleum coke into multiple fractions (12mm+6mm, 6mm+3mm). Their existing screens suffered rapid wear from abrasion required biweekly shutdowns for cloth changes.

[حل]: Installation of two parallel doubledeck Coke Vibration Screens fitted with modular polyurethane screen panels rated for high abrasion resistance.

[نتائج]: Screen panel life extended from two weeks average upto eight weeks between changes resulting in an estimated gain of over two hundred production hours annually per line while maintaining sharp separations
