1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Is your coke screening operation facing persistent, sự kém hiệu quả tốn kém? Dành cho người quản lý nhà máy và nhà thầu kỹ thuật, the final screening stage before blast furnace charging is a critical bottleneck with direct implications for productivity and cost. Những thách thức chung bao gồm:

Tạo tiền phạt quá mức: Aggressive vibration from standard screens can degrade coke, creating excessive 5mm fines that reduce furnace permeability and increase fuel rates. This can lead to a 25% loss in saleable product.
Thời gian ngừng hoạt động ngoài kế hoạch: Frequent screen deck replacements due to abrasive wear from sharp coke edges halt production lines. A single changeover can cost over 8 hours of lost processing time.
Phân loại sản phẩm không nhất quán: Inaccurate separation leads to offspec material, risking blast furnace performance penalties and customer rejections.
Gánh nặng bảo trì cao: Bearings and motors on conventional vibratory screens fail prematurely under heavy coke loads, driving up spare parts inventories and labor costs.
Môi trường & Rủi ro tuân thủ: Noncompliant components or excessive dust generation can conflict with stringent plant environmental policies.

Are you searching for a screening solution that protects your product integrity, extends equipment life, and ensures consistent compliance? The right RoHS compliant coke vibration screen directly addresses these operational and financial pressures.

2. TỔNG QUAN SẢN PHẨM Rohs Compliant Coke Vibration Screen Supply Chain

The RoHS Compliant Coke Vibration Screen is a heavyduty linear or elliptical motion vibrating screen engineered specifically for the sizing and scalping of metallurgical coke. Its design prioritizes material preservation, độ bền, and adherence to environmental substance directives.

Quy trình hoạt động:
1. Cho ăn & Phân bổ: Sized coke from the crusher or cooler is evenly distributed across the full width of the screen’s feed box.
2. Stratified Screening: Controlled vibratory motion stratifies the bed, allowing nearsize particles to contact the robust screen deck surface efficiently.
3. Accurate Separation: Material is separated into precise fractions (ví dụ., than cốc lò cao, coca hạt, gió nhẹ) via single or multideck configurations.
4. Phóng điện & vận chuyển: Sized fractions discharge onto dedicated conveyors for final stockpiling or furnace charging.

Phạm vi ứng dụng: Định cỡ sơ cấp của than cốc luyện kim (2580mm), scalp removal of oven push fines (>5mm), and nut coke separation. Ideal for integrated steel plants and merchant coke facilities.

Hạn chế: Not designed for sticky materials, wet screening applications, or extreme temperature variations beyond specified operating ranges without specialized modifications.

8.Câu hỏi thường gặp

Q1:What does 'RoHS compliant' mean specifically for this equipment?
It certifies that all applicable electrical components(động cơ,cảm biến,hệ thống dây điện)and homogeneous materials within wear parts(specific alloys,polyurethane compounds)are restrictedto levels below thresholds setfor lead,cadmiummercury,and other hazardous substances.This is criticalfor operationin oremarketing productsinto regulated regionslike the European Union.

Q2:Canyour screen handle 'green'orcoke directlyfromthe oven?
Our standard models are ratedfor material temperaturesup to100°C continuous.For hotcoke directlyfromthe oven(whichcan exceed300°C),we mustengineer aspecialized solutionwithhightemperaturedecks,vòng bi,and lubrication systems.Contact us todiscuss your specific feed temperature profile.
