1. Addressing Critical Screening Challenges in Coke Handling

Is your coke screening operation a source of consistent cost overruns and production bottlenecks? Inefficient particle separation directly impacts blast furnace efficiency, kualiti produk, dan belanjawan penyelenggaraan. Cabaran utama termasuk:
Blindness & Tersumbat: Adhesive coke fines and moisture cause rapid screen mesh blinding, memerlukan penutupan yang kerap untuk pembersihan manual. This can result in 1530% downtime on a single line.
Pemakaian Berlebihan & Penyelenggaraan: The abrasive nature of metallurgical coke accelerates wear on screen decks, mata air, dan mekanisme penggetar, leading to high parts replacement costs and unpredictable failures.
Taburan Saiz Tidak Konsisten: Poor separation allows undersize fines into the blast furnace feed or oversize material into the byproduct stream, disrupting furnace permeability and reducing yield.
Keletihan Struktur & Penghantaran Getaran: High Gforces needed for effective coke screening can damage support structures and transmit harmful vibrations to adjacent equipment.

Are you evaluating screening solutions that offer higher availability, costperton yang lebih rendah, and precise grading to protect downstream processes?

2. Gambaran Keseluruhan Produk: HeavyDuty Coke Vibration Screens

A Skrin Getaran Coke adalah kapasiti tinggi, bruteforce separator designed for the rigorous dry or slightly damp screening of metallurgical coke. Its primary function is to ensure a consistent, specificationgrade feed for blast furnaces while removing undersize coke breeze for other uses.

Aliran Kerja Operasi:
1. Pengenalan suapan: Runofoven (ROO) coke is uniformly distributed onto the inlet end of the inclined screen deck.
2. Pemisahan Getaran: An eccentric vibrator assembly imparts a linear or elliptical throwing motion, stratifying material and propelling it along the deck.
3. Pengasingan Saiz: Particles smaller than the screen aperture fall through as undersize (angin kok), while larger particles travel across the deck as productsized coke.
4. Pelepasan: Correctly sized coke discharges at the deck end for furnace charging; undersize material is collected separately.

Skop Permohonan: Saiz utama kok metalurgi (typically 25mm80mm fractions), scalping of oven discharge material, and recovery of coke from slag. Not recommended for wet screening or extremely sticky materials without specialized deck technology.
