1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Is your coke screening operation plagued by persistent, costly inefficiencies? Dành cho người quản lý nhà máy và nhà thầu kỹ thuật, the challenges of screening bulk metallurgical coke directly impact throughput, chất lượng sản phẩm, and bottomline profitability. Rào cản hoạt động phổ biến bao gồm:

chói mắt & Chuyển tiếp: Fine coke breeze and moisture cause screen mesh blinding, giảm diện tích sàng lọc hiệu quả. Đồng thời, undersize material carries over with the product stream, contaminating blast furnace feed and degrading its performance.
Thời gian ngừng bảo trì quá mức: The abrasive nature of coke accelerates wear on screen decks, tấm bên, and exciters. Frequent component replacement leads to unplanned downtime and high spare parts inventories.
Tách tiền phạt không hiệu quả: Inadequate separation of the 010mm fraction results in lost revenue from breeze sales and inefficient recycling within the coke plant.
Mệt mỏi kết cấu & Sự thất bại: High Gforces from traditional vibrators transfer damaging stress to the screen body and support structure, leading to weld cracks and catastrophic frame failures.
Tiêu thụ năng lượng cao: Inefficient drive systems and oversized motors run continuously, contributing to significant, nonproductive power costs.

Are you seeking a solution that reduces downtime by 30% or more while ensuring consistent product sizing? The answer lies in selecting a coke vibration screen engineered specifically to overcome these materialspecific challenges.

2. TỔNG QUAN SẢN PHẨM

The equipment in focus is a heavyduty Coke Classification Vibrating Screen, designed for highcapacity sizing of hot or cold metallurgical coke (25mm 80mm) from oven discharge and the subsequent separation of coke breeze (0mm 10mm).

Quy trình hoạt động:
1. Cho ăn & Phân bổ: Bulk coke is uniformly fed onto the robust feed box, which distributes the material across the full width of the primary screen deck.
2. Định cỡ chính: A highstrength wire mesh or punch plate deck performs the primary separation, allowing undersize material (breeze and small fractions) to pass through.
3. Sàng lọc thứ cấp & Xóa tiền phạt: A second deck further refines the separation, ensuring maximum recovery of marketable coke breeze.
4. Phóng điện: Correctly sized foundry or blast furnace coke discharges from the screen end, while separated fines are collected via a dedicated chute for processing or sale.

Phạm vi ứng dụng & Hạn chế:
This equipment is designed for dry or slightly moist coke screening in fixed plant installations. It is not suitable as a replacement for rotary breakers or for handling highly sticky materials without pretreatment. Maximum lump size should not exceed 150% of the nominal top deck aperture.

6. KỊCH BẢN ỨNG DỤNG

Integrated Steel Plant Coke Oven Battery Discharge

Thử thách: A major steel producer faced severe blinding on their existing screens due to residual moisture in quenched coke. This caused frequent overloads on downstream crushers and inconsistent blast furnace feed sizing (+/15phương sai mm).
Giải pháp: Implementation of two parallel heavyduty linear motion Coke Vibration Screens featuring nonblinding balltray decks on the fines removal section.
Kết quả: Screening efficiency stabilized at ≥94%. Oversize contamination was eliminated (<1%), protecting crusher integrity. The consistent product sizing contributed to a documented ~3% improvement in blast furnace burden permeability.

Merchant Coke Producer – Breeze Recovery

Thử thách: A merchant plant was losing significant revenue due to poor fines capture; an estimated 810% of saleable breeze was being incorrectly routed back into crusher feed circuits as "circulating load."
Giải pháp: Retrofitting a dedicated Coke Vibration Screen with a finemesh secondary deck into their product classification circuit postcrushing.
Kết quả: Breeze recovery increased from ~82% to over 95%, creating an additional revenue stream exceeding project payback within one year based on market prices for fuelgrade fines.
