1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Is your coke handling operation plagued by persistent inefficiency and unplanned maintenance? For plant managers overseeing coke screening, common challenges directly impact throughput and profitability. Excessive fines contamination in product streams can lead to customer rejections and revenue loss. Frequent screen cloth blinding from sticky, moist coke results in extended downtime for manual cleaning, tạm dừng toàn bộ dây chuyền xử lý. Premature wear of screen components due to the abrasive nature of coke forces a higherthanbudgeted spend on replacement parts. Vibration isolation failures transmit damaging harmonics to support structures, creating longterm asset integrity concerns. Are you facing rising operational costs, inconsistent product grading, and unreliable equipment availability? The right Màn hình rung Coke is not just a component; it’s a critical determinant of your plant’s continuous performance and bottom line.

2. TỔNG QUAN SẢN PHẨM

MỘT Màn hình rung Coke is a heavyduty industrial screening machine designed for the scalping, định cỡ, and dedusting of metallurgical coke and petroleum coke (than cốc). Its purpose is to separate material efficiently by particle size after crushing or prior to shipment and blast furnace charging.

Quy trình hoạt động:
1. Giới thiệu nguồn cấp dữ liệu: Bulk coke is conveyed onto the feed box of the inclined screen deck.
2. Tách rung: HighGforce linear or elliptical vibration stratifies material, forcing undersize particles through the specified screen cloth apertures.
3. Particle Stratification: Fines pass through first, followed by correctly sized product; nearsize material requiring more time to pass continues down the deck.
4. Phóng điện: Correctly sized oversize and undersize fractions are discharged from separate outlets onto designated conveyors or bins.

Phạm vi ứng dụng & Hạn chế:
This equipment is engineered for highcapacity dry screening of bulk solid coke. Optimal performance assumes controlled feed rates and material with surface moisture typically below 5% to minimize adhesion. It is not suitable as a substitute for a dewatering screen for slurry applications or for materials with significantly higher moisture content without specialized modifications.

6. KỊCH BẢN ỨNG DỤNG

[Steel Mill – Blast Furnace Feed] Thử thách: A major integrated steel mill experienced inconsistent blast furnace burden permeability due to excessive fines (<10mm) in their screened metallurgical coke feed.

[Giải pháp] Implementation of a customdesigned primary Coke Vibration Screen featuring a twodeck configuration with stringent cut points and aggressive antiblinding panels on the top deck.

[Kết quả] Fines content in furnace feed was reduced from an average of ~12% to a consistent <7%. This contributed to improved gas flow in the blast furnace, resulting in an estimated ~3% reduction in specific coke rate (kg coke/tonne hot metal).

[Petroleum Coke Processing Plant] Thử thách: A petcoke processor faced severe screen cloth blinding within hours when handling material with residual surface hydrocarbons ("sticky petcoke"), requiring multiple daily shutdowns.

[Giải pháp] Deployment of a specialized Coke Vibration Screen utilizing nonadhesive heated screen decks combined with ultraflexible urethane screen panels.

[Kết quả] Continuous operating time between blinding events increased from ~8 hours to over one week (~168+ hours), increasing plant availability by approximately two full production days per month.
