Rohs Compliant Coke Vibration Screen Supply Chain
1. PAINPOINT driven اوپننگ
Is your coke screening operation facing persistent, قيمتي غير موثريت? پلانٽ مينيجرز ۽ انجنيئرنگ ٺيڪيدارن لاءِ, the final screening stage before blast furnace charging is a critical bottleneck with direct implications for productivity and cost. عام چئلينج شامل آهن:
وڌ ۾ وڌ فائنس پيدا ڪرڻ: 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.
غير منصوبا بند وقت: 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.
متضاد پيداوار جي درجه بندي: Inaccurate separation leads to offspec material, risking blast furnace performance penalties and customer rejections.
اعلي سار سنڀال بار: Bearings and motors on conventional vibratory screens fail prematurely under heavy coke loads, driving up spare parts inventories and labor costs.
ماحولياتي & تعميل جا خطرا: 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. پيداوار جو جائزو
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, استحڪام, and adherence to environmental substance directives.
آپريشنل ڪم فلو:
1. کاڌو & ورهائڻ: 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 (مثال, ڌماڪي جي فرنس ڪوڪ, نٽ ڪوڪ, هوا) via single or multideck configurations.
4. خارج ٿيڻ & پهچائڻ: Sized fractions discharge onto dedicated conveyors for final stockpiling or furnace charging.
ايپليڪيشن جو دائرو: ميٽالرجيڪل ڪوڪ جي بنيادي ماپ (2580ايم ايم), scalp removal of oven push fines (>5ايم ايم), and nut coke separation. Ideal for integrated steel plants and merchant coke facilities.
حدون: Not designed for sticky materials, wet screening applications, or extreme temperature variations beyond specified operating ranges without specialized modifications.

8.FAQ
Q1:What does 'RoHS compliant' mean specifically for this equipment?
It certifies that all applicable electrical components(موٽرون,سينسر,وائرنگ)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,بيئرنگ,and lubrication systems.Contact us todiscuss your specific feed temperature profile.
