Penyasaran: Pengurus Loji, Pakar Perolehan, Engineering Contractors in Coke Processing & Steel Production

1. PEMBUKAAN PAINPOINT DRIVEN

Is your coke screening operation a persistent bottleneck? Inefficient particle separation directly impacts downstream blast furnace performance and overall plant profitability. Common challenges with substandard or worn skrin getaran kok termasuk:

Pemindahan Denda Berlebihan: Poor screening efficiency allows undersized coke fines (<10mm) to enter the blast furnace charge, disrupting gas permeability, increasing coke rate, and raising production costs. Industry estimates suggest a 1% increase in fines can reduce furnace efficiency by 23%.
Masa Henti yang kerap untuk Penyelenggaraan: Premature failure of screen decks, galas, or vibrator assemblies leads to unplanned shutdowns. Each hour of lost screening capacity can stall an entire coke handling line.
Kos Operasi yang Tinggi: Constant replacement of screen cloths due to accelerated wear from abrasive coke, coupled with high energy consumption from inefficient drive systems, menghakis margin anda.
Alam sekitar & Kebimbangan Keselamatan: Excessive dust generation at the transfer points due to poor material stratification and sealing issues creates hazardous working conditions and compliance challenges.

Are you evaluating coke vibration screen suppliers to find a solution that delivers reliability without a prohibitive capital outlay? The following outlines what constitutes a genuinely affordable and highperformance coke screening solution.

2. GAMBARAN KESELURUHAN PRODUK: HeavyDuty Coke Classification Screens

This product is a heavyduty linear motion vibrating screen engineered specifically for the classification of metallurgical coke. Its design focuses on robustness and precise separation under highload, abrasive conditions.

Aliran Kerja Operasi:
1. Suapan & Pengedaran: Sized coke from the crusher is evenly fed onto the inclined screen deck via a feed box.
2. Stratifikasi & Perpisahan: Dual counterrotating exciters generate a linear throwing motion, bahan berstrata. Oversize particles (mis., +25mm) travel across the deck surface, while fines pass through the apertures.
3. Pelepasan: Coke bersaiz betul (mis., 2580mm) is discharged as product, while undersize fines are collected separately for recycling or other uses.

Skop Permohonan: Saiz utama kok metalurgi (kok relau letupan), pemisahan angin kok, dan scalping pelepasan ketuhar. Ideal for capacities from 200 ke 1500+ Tph.

Batasan: Tidak direka untuk bahan melekit atau lembap tanpa rawatan dek khusus. Maximum lump size is typically limited to 1/3 of the feed inlet width.
