Are your coke screening operations plagued by persistent inefficiencies that directly impact your bottom line? وتشمل التحديات المشتركة:

التوقف المفرط: Frequent screen cloth blinding and premature wear from abrasive coke fines, leading to unscheduled maintenance stops and lost production hours.
تصنيف المنتج غير متناسق: Inefficient separation resulting in offspec material—oversize particles contaminating the nut coke fraction or excessive fines in the blast furnace feedstock—compromising downstream process efficiency.
تكاليف تشغيلية عالية: Constant replacement of screen decks, excessive energy consumption from inefficient vibration mechanisms, and high labor costs for manual clearing and maintenance.
مخاوف تتعلق بالنزاهة الهيكلية: Vibration transmission to support structures causing fatigue cracks and foundation issues, creating longterm plant safety and capital expenditure risks.
انبعاث الغبار & الانسكاب: Poor sealing and excessive vibration exacerbate housekeeping issues, creating environmental control challenges and product loss.

2. نظرة عامة على المنتج

The Coke Vibration Screen is a heavyduty, highcapacity screening machine engineered for the precise size classification of metallurgical coke. It separates crushed coke into defined fractions—such as blast furnace coke, فحم الكوك, and breeze—critical for optimal furnace operation.

سير العمل التشغيلي:
1. مقدمة الأعلاف: Crushed coke is uniformly distributed onto the feed box of the inclined screen deck(ق).
2. الفصل الاهتزازي: A highefficiency vibrator assembly imparts a linear or elliptical motion, stratifying material and propelling it across the screening surface.
3. ​​SizeBased Stratification: Particles smaller than the screen aperture fall through as undersize, while larger particles travel across the deck to discharge as oversize.
4. تفريغ الكسر: Separated material streams are discharged via dedicated chutes into designated collection hoppers or conveyors for further processing or shipment.

نطاق التطبيق & القيود:
نِطَاق: Ideal for primary sizing of hot or cold metallurgical coke in coke plants, مصانع الصلب, ومحطات المناولة السائبة. Effective for capacities ranging from 200 ل 1500+ طن في الساعة.
القيود: Not designed for sticky materials without pretreatment (على سبيل المثال, التسخين). Performance is contingent on proper feed rate control and consistent moisture content management.
