1. PEMBUKAAN PAINPOINT DRIVEN

Adakah operasi pengendalian kok anda dibelenggu oleh kualiti produk yang tidak konsisten, penjanaan denda yang berlebihan, and unplanned maintenance halts? Bagi pengurus loji yang mengawasi pemeriksaan kok, common challenges directly impact profitability and throughput. Adakah anda mengalami:

Membutakan & Pemindahan: Moisture or sticky fines blinding screen decks, causing product contamination and forcing premature shutdowns for manual cleaning.
Excessive Downtime: Frequent bearing failures or structural fatigue on vibrating screens leading to 2040 hours of unscheduled downtime annually for repairs and parts replacement.
Kos Penyelenggaraan Tinggi: The abrasive nature of coke accelerating wear on screen panels, dek, dan penguja, resulting in high consumable costs and labor for changeouts.
Inefficient Sizing: Inconsistent feed rates or improper vibration dynamics producing offspec material, leading to customer rejections or reprocessing costs.

Soalan intinya ialah: bagaimana anda boleh mencapai tepat, reliable coke classification while maximizing equipment uptime and minimizing total cost of ownership? Jawapannya terletak pada memilih tujuan yang direkayasa Skrin Getaran Coke.

2. GAMBARAN KESELURUHAN PRODUK

A Skrin Getaran Coke is a heavyduty industrial screening machine designed for the dry separation of metallurgical coke into precise size fractions—typically nut coke, angin sepoi-sepoi, and lump coke—after the quenching process. Its robust construction handles highly abrasive materials while resisting corrosion from residual moisture.

Aliran Kerja Operasi:
1. Suapan Terkawal: Quenched coke is conveyed onto the screen’s feed box, distributing material evenly across the full width of the top deck.
2. Pemisahan Intensiti Tinggi: A dualvibrator mechanism imparts a linear or elliptical motion, stratifying material and propelling particles across the screen cloths.
3. Saiz Tepat: Oversize material travels across the top deck apertures, while correctly sized particles pass through to lower decks for further fractionation.
4. Pelepasan & Pengangkutan: Separated fractions discharge via dedicated chutes onto designated conveyors for stockpiling or direct feed to blast furnaces.

Skop Permohonan & Batasan:
Skop: Ideal for sinter plants, sistem pengecasan relau letupan, and foundry operations requiring strict size control (mis., 2540mm nut coke). Effective for hot or cold coke screening postquenching.
Batasan: Tidak direka untuk proses saringan basah atau sebagai pengganti untuk skrin scalping yang mengendalikan sangat besar (+300mm) feedstock without prior crushing. Performance is contingent on proper installation on a structurally adequate support base.
