1. PEMBUKAAN PAINPOINT DRIVEN

Adakah operasi pengendalian kok anda menghadapi kesesakan yang berterusan dan kos yang semakin meningkat? Peringkat saringan selalunya merupakan titik kegagalan kritikal, directly impacting downstream processing and overall plant profitability. Cabaran biasa termasuk:

Membutakan & Pemindahan: Kelembapan dan zarah kok halus melekat pada dek skrin, blinding apertures and forcing material to bypass the screening process. This leads to product contamination, inefficient size separation, and increased wear on crushers.
Masa Henti Berlebihan untuk Penyelenggaraan: Frequent breakdowns of vibratory mechanisms, perubahan kain skrin, and structural fatigue repairs halt your entire production line. Unplanned downtime in a coke plant can cost tens of thousands per hour in lost throughput.
Penggunaan Tenaga Tinggi & Tekanan Struktur: Inefficient vibration systems draw excessive power while transmitting damaging forces to the support structure. This increases operational costs and creates longterm integrity concerns for the screening station.
Penggredan Produk Tidak Konsisten: Variable feed rates and inefficient screen action result in offspec product. This can lead to rejected loads from steel mill customers or reduced efficiency in anode baking plants.

Are you evaluating a coke vibration screen manufacturer based on initial cost alone, or are you calculating the total cost of ownership—factoring in uptime, buruh penyelenggaraan, and energy efficiency?

2. GAMBARAN KESELURUHAN PRODUK: Skrin Bergetar Coke HeavyDuty

Peralatan ini berkapasiti tinggi, linear motion vibrating screen engineered specifically for the abrasive and demanding environment of met coke and petroleum coke sizing. Its design focuses on reliable separation of coke fractions (mis., kok relau letupan, kacang kok, angin sepoi-sepoi) after crushing.

Aliran Kerja Operasi:
1. Suapan & Pengedaran: Kokas yang dihancurkan dimasukkan ke dalam kotak suapan yang teguh, which evenly distributes the material across the full width of the primary screen deck.
2. Positive Material Stratification: A dualshaft vibrator assembly generates a forceful linear motion. Tindakan ini menstratakan katil material, forcing fines downward to contact the screen media while conveying oversize along the deck.
3. Precise Size Separation: Multiple deck levels (biasanya 13) equipped with tailored screen panels (Wire mesh, poliuretana, or perforated plate) separate the coke into precise size fractions (mis., +50mm, 50mm+25mm, 25mm).
4. Pelepasan & Pengangkutan: Correctly sized fractions are discharged via dedicated chutes onto separate conveyors for stockpiling or direct loading.

Skop Permohonan: Saiz utama dan sekunder metalurgi (bertemu) coke and petroleum (haiwan peliharaan) coke in steel plants, carbon anode plants, and bulk coke handling terminals.

Batasan: Not designed for sticky materials without predrying or specialized deck treatments. Maximum feed size is limited by deck construction and impact resistance.

6. SENARIO APLIKASI

Penyediaan Suapan Relau Letupan Loji Keluli

Cabaran: A major integrated steel mill experienced chronic blinding on their secondary coke screens due to seasonal moisture increases. This caused excessive 10mm fines ("angin sepoi-sepoi") reporting to the BF skip fraction (>12%), disrupting furnace permeability.
Penyelesaian: Installation of two tripledeck linear motion screens featuring nonblinding polyurethane deck panels on lower decks combined with heated deck technology on top decks.
Keputusan: Screening efficiency for 10mm removal improved from 84% ke 96%. Fines content in BF feed stabilized below 5%, menyumbang kepada anggaran 2% reduction in specific coke rate within six months.

Loji Pengkalsinan Coke Petroleum

Cabaran: An anodegrade calciner needed precise sizing (30mm+15mm) of green petroleum coke but faced rapid wear of wire mesh panels every three weeks due to extreme abrasiveness.
Penyelesaian: Implementation of customdesigned vibrating screens using modular tensioned polyurethane panel systems with ultrahigh abrasion resistance ratings.
Results Screen panel life extended from three weeks to over fourteen weeks between changes Annual maintenance costs for screen media fell by approximately $65k per unit

Bulk Coke Handling Terminal

Challenge A transshipment terminal required highcapacity screening (>2200 MTPH) but had strict limitations on allowable dynamic load transferred into their existing elevated gallery structure
Solution Engineers specified low dynamic force linear motion screens incorporating outofbalance motors configured specifically for force cancellation
Results Required throughput was achieved while transmitted dynamic forces were measured at 28 below the gallery s design limits eliminating need for costly structural reinforcement
