ISOCertified Coke Vibration Screen: Engineered for Precision, Built for Endurance

1. PAINPOINT DRIVEN OPENING

Managing coke screening operations presents distinct and costly challenges. Inconsistent particle size distribution directly impacts downstream blast furnace efficiency and can increase fuel consumption. Frequent screen cloth blinding from sticky fines leads to extended downtime for manual cleaning, while premature structural fatigue from constant, highimpact loads results in unexpected failures and costly component replacement. The abrasive nature of metallurgical coke accelerates wear on critical parts, driving up your maintenance budget and inventory costs.

Are these scenarios familiar? Is your current screening solution causing bottlenecks in your material handling circuit? How much production time and maintenance capital are you losing annually to inefficient screening?

2. PRODUCT OVERVIEW

The ISOCertified Coke Vibration Screen is a heavyduty linear motion screening machine designed for the precise size classification of metallurgical coke in demanding processing environments. Its operational workflow is engineered for reliability: (1) Feed material is evenly distributed across the full width of the screen deck; (2) A dualshaft vibrator assembly generates a linear throwing motion, conveying and stratifying the coke; (3) Precisely sized apertures in the robust screen media facilitate accurate separation; (4) Oversize and undersize fractions are discharged at designated outlets. This equipment is specifically configured for hot or cold coke, with capacities suited for midtohighvolume processing plants. It is not designed for wet screening applications or as a replacement for crushers in primary size reduction.

6. APPLICATION SCENARIOS

[Integrated Steel Plant] Challenge: A major steel producer experienced rapid blinding of screens in their coke breeze circuit, requiring biweekly shutdowns for cleaning, causing bottlenecking in their sinter plant feed preparation.

[Merchant Coke Producer] Challenge: A merchant coke facility faced high costs from frequent replacement of standard wire mesh screens due to abrasion, coupled with inconsistent sizing that led to customer complaints over undersized fractions.

[Solution & Results]

A doubledeck ISOCertified Coke Vibration Screen was installed with antiblinding polyurethane panels on the top deck and a reinforced rubber panel on the bottom deck.
Results:
Maintenance intervals extended from two weeks to over eight weeks.
Screening efficiency stabilized at 94%, ensuring consistent breeze quality for sintering.

A heavyduty singledeck unit was supplied featuring a modular deck system with abrasionresistant steelframed polyurethane panels.
Results:
Panel replacement time reduced from 16 hours to under 6 hours.
Annual screen media costs decreased by an estimated 35%.
Product consistency improved significantly as measured by standard deviation in particle size analysis.
