1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Is your coke processing operation struggling with persistent bottlenecks and escalating costs at the screening stage? Common challenges with conventional screens directly impact your bottom line. Bạn đang trải nghiệm:
chói mắt & Thời gian ngừng hoạt động: Độ ẩm và các hạt than cốc mịn làm tắc nghẽn sàn lưới, yêu cầu tắt máy thường xuyên để làm sạch thủ công, tiêu tốn hàng trăm giờ sản xuất hàng năm.
Inconsistent Grading: Poor separation leads to offspec product (undersize in metallurgical coke, oversize in breeze), resulting in product rejection and revenue loss.
Excessive Maintenance: The abrasive nature of coke accelerates wear on screen panels and components, driving up spare parts costs and labor for replacements.
Tiêu thụ năng lượng cao: Inefficient vibration mechanisms and heavyduty designs lead to disproportionately high power usage per ton of material processed.
Mệt mỏi kết cấu: Không thay đổi, highimpact loads from bulk coke can cause weld cracks and structural failures in the screen body, risking major unplanned downtime.

Câu hỏi trọng tâm dành cho các nhà quản lý nhà máy là rõ ràng: làm thế nào bạn có thể đạt được sự tin cậy, continuous coke classification with lower operational expenditure and maximized equipment lifespan?

2. TỔNG QUAN SẢN PHẨM

Màn hình rung Coke Trung Quốc là một nhiệm vụ nặng nề, linear motion vibrating screen engineered specifically for the highvolume sizing and scalping of metallurgical coke, than cốc dầu mỏ, và than cốc đúc. It is designed to handle the unique abrasiveness, Tỉ trọng, and size ranges of bulk coke in processing plants.

Quy trình hoạt động:
1. Cho ăn & Phân bổ: Bulk coke from crushers or ovens is fed onto the screen’s robust feed box, which evenly distributes material across the full width of the screening surface.
2. Phân tầng hiệu quả & Sự tách biệt: Dual vibrator motors generate a linear throwing motion, stratifying material rapidly. Coke particles smaller than the screen panel apertures pass through as undersize product.
3. Phóng điện: Correctly sized oversize material travels along the deck length and discharges at the end, while undersize material collects in a hopper below.

Phạm vi ứng dụng: Kích thước chính (lột da đầu) than cốc runofoven, secondary screening of crushed coke (ví dụ., 2540than cốc lò cao mm), tẩy bụi (coke breeze removal), and dewatering applications.

Hạn chế: Not designed for extremely sticky materials without specialized deck treatments. Maximum lump size is typically limited to 200mm; alternative solutions are required for larger primary runofmine scalping.

Metallurgical Coke Plant – Blast Furnace Feed Preparation

Challenge A major steel plant faced frequent blinding on traditional screens during humid months, causing a ~20% drop in throughput for their critical +25mm BF coke fraction and generating excessive 10mm fines.
Solution Installation of twotier China Coke Vibration Screens equipped with nonblinding polyurethane panels featuring tapered apertures.
Results Screening efficiency stabilized at ≥94%. Annual production of onspec (+25mm) coke increased by an estimated 75,000 tấn. Maintenance downtime for screen cleaning was reduced by over 400 hours per year.

Petroleum Coke Calcining Plant – Green Coke Scalping

Challenge A calciner needed reliable precalcination scalping of green petroleum coke at high temperatures (~150°C feed) to remove sub2” fractions before kiln entry. Existing screens suffered rapid thermal warping and bearing failures.
Solution Deployment of hightemperature adapted China Coke Vibration Screens featuring heatresistant seals on bearings and thermally stable deck components.
Results The solution provided continuous operation at elevated temperatures without performance degradation. Bearing service life extended from under six months to over two years between changes.
