1. PEMBUKAAN PAINPOINT DRIVEN

Is your coke handling operation facing persistent bottlenecks and rising costs? 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 dek skrin buta, manakala bahan bersaiz besar dibawa ke dalam silo produk siap. Ini menghasilkan produk offspec, penolakan pelanggan, and costly rehandling.
Masa Henti Berlebihan untuk Penyelenggaraan: Kegagalan galas yang kerap, penggantian kain skrin, and structural weld cracks demand constant attention from your maintenance crew, stealing valuable production hours.
Penggunaan Tenaga Tinggi & Penghantaran Getaran: Inefficient vibratory mechanisms consume excess power and transmit destructive forces to the support structure, leading to accelerated wear on the entire screening station.
Pemisahan Gred Tidak Konsisten: An inability to maintain precise cut points leads to product contamination, reducing the market value of your metallurgical or foundry coke.

Are you evaluating how a purposeengineered Skrin Getaran Coke can reduce your total cost of ownership, increase screening availability above 95%, dan memastikan kualiti produk yang konsisten?

2. GAMBARAN KESELURUHAN PRODUK

A Skrin Getaran Coke adalah kapasiti tinggi, heavyduty screening machine designed for the scalping, saiz, and dedusting of hot or cold metallurgical coke in battery, pelindapkejutan, and sorting plants. Its core function is to separate coke feedstock into precise size fractions (mis., kok relau letupan, kacang kok, angin sepoi-sepoi) sambil menghapuskan denda.

Aliran Kerja Operasi:
1. Bulk coke from the quench car or feed conveyor is discharged onto the screen's robust feed box.
2. Highmagnitude, linear or elliptical vibratory motion stratifies the material bed and propels it across the multideck screening surfaces.
3. Undersize material passes through sequentially smaller apertures on each deck.
4. Correctly sized fractions discharge at designated outlets for conveyor transfer to storage bins or loading stations.
5. Material bersaiz besar (mis., +80mm) exits at the screen's discharge end for potential crushing or recirculation.

Skop Permohonan: Saiz utama dan sekunder kok metalurgi, pemulihan angin kok, prasaringan sebelum dihancurkan. Not suitable for sticky materials without specialized deck technology or as a replacement for a crusher.
