Is there a screening solution engineered to withstand the abrasive nature of metallurgical coke while delivering precise separation with maximum uptime?

2. نظرة عامة على المنتج

The ISOCertified Coke Vibration Screen is a heavyduty linear or elliptical motion vibrating screen specifically engineered for the dry separation of metallurgical coke into precise size fractions (على سبيل المثال, فحم الكوك فرن الانفجار, فحم الكوك, نسيم). Its robust design addresses the unique abrasiveness, كثافة, and size range of coke particles.

سير العمل التشغيلي:
1. يٌطعم & توزيع: Sized coke from crushers is evenly distributed across the full width of the screen’s feed box.
2. التقسيم الطبقي & الانفصال: HighGforce vibration stratifies material; fines pass through the configured screen cloth apertures while oversize travels toward the discharge end.
3. تسريح: Correctly sized fractions are discharged into separate chutes or conveyors for stockpiling or shipment.

نطاق التطبيق: Primary and secondary screening of metallurgical coke in coke plants, مصانع الصلب, ومحطات المناولة السائبة. Ideal for sizing ranges from 80mm down to 05mm breeze.

القيود: Not designed for wet screening applications or for materials with extreme temperature (>150درجة مئوية) without specific modifications.
