1. فتحة مدفوعة بنقطة الألم

هل تعاني عملية فحص فحم الكوك من استمرارية العمل؟, أوجه القصور المكلفة? لمديري المصانع والمقاولين الهندسيين, the challenges of screening metallurgical coke directly impact throughput, جودة المنتج, والربحية النهائية. تشمل نقاط الألم الشائعة:

توليد الغرامات المفرطة: Aggressive or poorly tuned vibration can degrade premium coke into undersized fines, reducing valuable product yield and creating excess waste material.
المسببة للعمى & تحمل أكثر: Sticky coke breeze and moisture cause screen mesh blinding, بينما يؤدي الاهتزاز غير الكافي إلى ترحيل المواد. Both scenarios force frequent stoppages for manual cleaning and result in inconsistent size fractions.
ارتفاع فترات توقف الصيانة: ثابت, heavyduty operation leads to premature failure of screen decks, الينابيع, and vibrator motors. Unplanned downtime for repairs disrupts blast furnace feed schedules.
Inefficient Capacity Management: A singlescreen setup cannot adapt to varying feed rates or different size specifications, creating bottlenecks in highvolume operations.

Are you facing rising operational costs due to screen maintenance and product loss? Is your current equipment failing to deliver consistent grade separation under full load? The solution requires a purposeengineered approach to material handling.

2. نظرة عامة على المنتج

The Coke Vibration Screen is a heavyduty industrial screening machine designed for the precise separation of metallurgical coke into defined size fractions (على سبيل المثال, فحم الكوك فرن الانفجار, فحم الكوك). It operates on the principle of applied vibration to stratify and convey material across a screening surface.

سير العمل التشغيلي:
1. تغذية تسيطر عليها: Sized coke from the crusher is evenly distributed onto the inlet end of the vibrating screen deck via a feed box or conveyor.
2. التقسيم الطبقي & الانفصال: عالية التردد, lowamplitude vibration fluidizes the bed of material. Smaller particles sift through the apertures of the screen cloth (لوحة), while oversized particles travel across the deck surface.
3. التفريغ الفعال: Correctly sized material (من خلال) discharges from a lower outlet chute. مادة كبيرة الحجم (المبالغ) travels along the deck length and discharges from the end, directed to downstream processes.

نطاق التطبيق: Primary and secondary sizing of metallurgical coke in coke plants, مصانع الصلب, and ferroalloy facilities. Suitable for hot or cold coke screening.

القيود: Not designed for wet screening or slurries without significant modification. Maximum lump size is constrained by feed chute and deck design specifications.
