1. PAINPOINT DRIVEN OPENING

Is your bulk material handling operation losing profitability to inefficient screening? Common challenges with standard vibration screens directly impact your bottom line. Are you experiencing:
Excessive Downtime for Screen Cloth Changes: Frequent blinding and wear of screen media halts production, costing thousands per hour in lost output and labor.
Inconsistent Product Gradation: Poor stratification and material carryover result in offspec product, leading to customer rejections, reprocessing costs, and wasted raw materials.
High Maintenance & Energy Costs: Inefficient drive systems and structural failures from unbalanced vibration demand constant attention and consume excessive power.
Limited Process Flexibility: A single screen cannot adapt to varying feed rates or material characteristics, forcing compromises in your entire process flow.

What if a screening solution could systematically address these issues, turning a cost center into a reliable efficiency driver?

2. PRODUCT OVERVIEW

The White Label Coke Vibration Screen is a highcapacity, linear motion screening machine engineered for the precise sizing and scalping of bulk materials like foundry coke, metallurgical coke, and similar aggregates. Its design focuses on durability and consistent performance in demanding mineral processing and material handling applications.

Operational Workflow:
1. Controlled Feed: Material is evenly distributed across the full width of the screen inlet.
2. Efficient Stratification: The dualvibrator generated linear motion rapidly stratifies material, forcing fines downward to the screen surface while conveying oversize toward the discharge end.
3. Accurate Separation: Sized fractions pass through precisely tensioned screen panels or are discharged as oversize at designated outlets.
4. Continuous Discharge: Separated material streams are conveyed away for further processing or stockpiling.

Application Scope & Limitations:
Ideal For: Dry screening of coke (foundry, metallurgical), sinter feed, recycled aggregates, crushed stone, and similar granular materials (typically 0.1mm to 150mm).
Limitations: Not designed for wet screening processes, highly abrasive slurries, or sticky, claybound materials without significant modification.

6. APPLICATION SCENARIOS

Foundry Coke Production Plant – Final Product Sizing

Challenge: A major foundry needed consistent +25mm 50mm lump coke but their existing screens suffered rapid blinding with fines (<5mm), causing offspec product batches every shift.
Solution: Installation of a twodeck White Label Coke Vibration Screen with top deck polyurethane panels (50mm aperture) and bottom deck wire mesh (25mm aperture).
Results: Achieved consistent product gradation (>98% within spec). Panel blinding was eliminated due to effective linear stratification; media change intervals extended from weekly to quarterly.

Integrated Steelworks – Sinter Plant Feed Preparation

Challenge: Fluctuations in crusher output led to overload conditions on sinter feed screens downstream, causing frequent bearing failures and unscheduled downtime exceeding 40 hours monthly.
Solution: Deployment of a heavyduty model with oversized vibrator bearings rated for higher Gforces and an integrated loadsensing control system that adjusts feed rate via PLC interface.
Results: Field data shows a complete elimination of vibrationrelated bearing failures in the first year of operation. Plant availability increased by over 3%, translating directly to increased sinter production.
