Fda Approved Coke Vibration Screen Dealer
FDA Approved Coke Vibration Screen Dealer: Precision Screening for Critical Applications
The Cost of Inconsistent Screening in Coke Processing
Every hour of unscheduled downtime in coke screening operations costs between $8,000 and $15,000 in lost production capacity. Plant managers face three persistent challenges: particle size deviation exceeding 5% from specification, screen blinding that reduces throughput by 2040% in highmoisture environments, and premature wear of screen decks that forces replacement every 90120 days. Engineering contractors report that 60% of coke handling system failures originate at the screening stage.
Your screening equipment must maintain strict particle size distribution for downstream processes—whether for anodegrade petroleum coke, calcined coke, or metallurgical coke. Can your current system consistently deliver 95% screening efficiency at rated capacity? Does your screen deck withstand the abrasive nature of coke without requiring weekly maintenance? Are you meeting FDA compliance requirements for coke used in foodgrade applications?
Product Overview: FDA Compliant Coke Vibration Screen
The FDA Approved Coke Vibration Screen is a linear motion vibrating screener engineered specifically for the unique material characteristics of petroleum coke, calcined coke, and metallurgical coke. This equipment operates on a dualmotor excitation principle, generating controlled linear vibration that moves material across the screen surface while stratifying particles by size.
Operational Workflow:
1. Feed Introduction: Material enters through the inlet chute at controlled feed rates (50500 TPH depending on model)
2. Stratification: Linear vibration causes particle separation by density and size across the first 30% of screen length
3. Classification: Material passes through 24 deck configurations with mesh sizes from 1mm to 50mm
4. Oversize Discharge: +6mm particles exit through the oversize outlet for recrushing or rejection
5. Undersize Collection: 6mm fines pass through to collection conveyors or storage
Application Scope: Suitable for dry coke screening with moisture content below 12%. Not recommended for slurry or wet screening applications. FDA compliance applies to foodcontact coke products where material purity standards must be maintained.

Frequently Asked Questions
Q: What specific FDA regulations does this screen comply with for coke applications?
A: The equipment meets 21 CFR 175.300 (resinous and polymeric coatings) and 21 CFR 177.2600 (rubber articles intended for repeated use) for foodcontact surfaces. All contact materials have FDA letter of compliance documentation available for audit purposes.
Q: Can this screen handle coke with moisture content above 12%?
A: Standard configuration is rated for up to 12% moisture. For higher moisture applications (1218%), we recommend the heated deck option or predrying system. Above 18%, a different screening technology (such as fluidized bed) may be more appropriate.
Q: What is the typical lead time for delivery?
A: Standard models ship within 812 weeks from order. Custom configurations with FDA documentation require 1216 weeks. Expedited delivery (68 weeks) is available with a 15% premium.
Q: How does the FDA compliance documentation process work?
A: Each unit ships with a compliance package including material certifications, surface finish test reports, and a certificate of conformance. Thirdparty audit documentation is available for an additional fee.
Q: What maintenance is required for the selfcleaning ball tray system?
A: Inspect rubber balls monthly for wear (replace at 50% diameter reduction). Clean ball trays quarterly to remove fines buildup. Ball replacement cost is approximately $200$500 per deck, depending on size.
Q: Can this screen be retrofitted into existing coke handling systems?
A: Yes. The modular design allows for integration with existing conveyors, chutes, and support structures. We provide engineering drawings and installation support. Retrofit typically requires 35 days of downtime.
Q: What is the expected ROI period for this equipment?
A: Based on field data from 47 installations, typical ROI is 814 months from reduced product giveaway, lower maintenance costs, and improved throughput. Energy savings alone provide 1525% reduction in operating costs.
