1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Hoạt động xử lý than cốc của bạn có gặp khó khăn do tắc nghẽn dai dẳng và chi phí bảo trì leo thang không?? Dành cho người quản lý nhà máy và nhà thầu kỹ thuật, sàng lọc không hiệu quả ảnh hưởng trực tiếp đến kết quả kinh doanh. Những thách thức chung bao gồm:

chói mắt & Chuyển tiếp: Khỏe, sticky coke particles blind screen decks, reducing effective screening area and forcing material carryover into the wrong product streams. This contaminates product grades and necessitates costly reprocessing.
Thời gian ngừng hoạt động quá mức & BẢO TRÌ: Traditional screens with complex drive mechanisms and numerous moving parts require frequent lubrication, belt changes, and bearing replacements, dẫn đến việc ngừng hoạt động ngoài kế hoạch.
Tiêu thụ năng lượng cao: Inefficient vibratory systems operate at constant high power, regardless of feed conditions, wasting significant energy over thousands of operational hours.
Mệt mỏi kết cấu & Sự thất bại: The intense, reciprocating forces from conventional exciters transmit high stress to the screen body and support structure, leading to weld cracks, side plate failures, and shortened equipment lifespan.

Are you seeking a coke vibration screen solution engineered to minimize these operational burdens while maximizing throughput and product consistency?

2. TỔNG QUAN SẢN PHẨM

Our engineered service provides heavyduty Coke Vibration Screens, specifically designed for the abrasive and demanding environment of coke handling in steel production, cây anode, and calcining operations.

Quy trình hoạt động:
1. Cho ăn & Phân bổ: Sized coke from crushers or ovens is fed onto the screen’s robust feed box for even distribution across the full width of the screening deck.
2. HighEfficiency Stratification: Một sức mạnh, linear vibratory motion stratifies the material bed, forcing fines downward through the screen media while conveying oversize toward the discharge end.
3. Precise Separation: Multiple deck configurations allow for precise separation into two or three distinct product streams (ví dụ., nut coke from breeze).
4. Xả có kiểm soát: Separated fractions are discharged via dedicated chutes for downstream processing or stockpiling.

Phạm vi ứng dụng: Primary and secondary screening of metallurgical (đã gặp) than cốc, petroleum coke (than cốc), and calcined coke in sizing ranges typically from 080mm.

Hạn chế: Not designed for extremely fine classification (<1mm) which requires specialized fine screening technology, or for materials at temperatures exceeding 250°C without specific design adaptations.
