1. PEMBUKAAN PAINPOINT DRIVEN

Is your coke screening operation facing persistent, ketidakcekapan yang mahal? Untuk pengurus loji dan kontraktor kejuruteraan, the final screening stage before blast furnace charging is a critical bottleneck with direct implications for productivity and cost. Cabaran biasa termasuk:

Penjanaan Denda Berlebihan: 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.
Downtime yang tidak dirancang: 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.
Penggredan Produk Tidak Konsisten: Inaccurate separation leads to offspec material, risking blast furnace performance penalties and customer rejections.
Beban Penyelenggaraan Tinggi: Bearings and motors on conventional vibratory screens fail prematurely under heavy coke loads, driving up spare parts inventories and labor costs.
Alam sekitar & Risiko Pematuhan: 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. GAMBARAN KESELURUHAN PRODUK

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, ketahanan, and adherence to environmental substance directives.

Aliran Kerja Operasi:
1. Suapan & Pengedaran: 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 (mis., kok relau letupan, kacang kok, angin sepoi-sepoi) via single or multideck configurations.
4. Pelepasan & Pengangkutan: Sized fractions discharge onto dedicated conveyors for final stockpiling or furnace charging.

Skop Permohonan: Saiz utama kok metalurgi (2580mm), scalp removal of oven push fines (>5mm), and nut coke separation. Ideal for integrated steel plants and merchant coke facilities.

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