Headline: Reduce Coke Fines & Downtime: Direct Wholesale Pricing on Industrial Coke Vibrating Screens

Is Your Current Screening Process Costing You in Fines and Maintenance?

Every ton of coke that passes through an undersized or inefficient screen represents lost revenue. Plant managers in metallurgical and foundry coke operations face three persistent challenges: excessive fines generation (often 58% above target), blinding of screen media due to moisture and tar content, and structural fatigue from highimpact loads. These issues lead to annual losses of $50,000–$150,000 in rehandling costs and lost product value. Are your operators spending more time clearing decks than monitoring throughput? Does your current equipment handle the abrasive, hightemperature nature of coke without frequent weld repairs? A dedicated coke vibration screen addresses these specific material handling constraints.

Product Overview: HeavyDuty Linear Motion Sizing

This equipment is a heavyduty linear motion vibrating screen engineered specifically for the dry and wet screening of metallurgical coke, petroleum coke, and foundry coke. It operates on a dualshaft exciter mechanism that generates a straightline stroke, providing aggressive material conveyance and efficient stratification.

Operational Workflow:
1. Feed Introduction: Material enters the feed box, distributed evenly across the full width of the screen deck.
2. Stratification: HighGforce linear motion separates fine particles from larger fractions within the first 1/3 of the deck.
3. Sizing: Material passes over polyurethane or perforated metal panels. Oversize (+25mm or +50mm) travels to the discharge end.
4. Fines Removal: Undersize material (6mm or 10mm) passes through the deck into a collection hopper.
5. Discharge: Three distinct product streams (oversize, midsize, fines) are directed to downstream conveyors.

Application Scope: Ideal for classifying coke breeze from nut coke, or separating blast furnace grade coke from smalls. Limitations: Not recommended for slurries with >15% moisture content without specialized selfcleaning media; maximum feed temperature should not exceed 120°C (248°F) for standard rubber spring mounts.

Application Scenarios

Metallurgical Coke Plant – Primary Sizing

Challenge: A steel mill was experiencing 12% fines in their blast furnace coke (+50mm fraction), causing reduced permeability in the furnace and higher coke rate consumption.
Solution: Installed a CS2448 coke vibration screen with 50mm polyurethane panels to replace a worn vibrating grizzly.
Results: Fines in oversize product dropped to 2.5%. Blast furnace coke rate reduced by 8 kg/ton of hot metal, saving the plant $1.2M annually in coke purchases.

Foundry Coke Producer – Breeze Recovery

Challenge: A foundry coke operation was losing 15% of saleable nut coke (2040mm) into the breeze pile due to poor screen separation.
Solution: Deployed a CS1836 unit with a dualdeck configuration (40mm top, 20mm bottom) and variable speed drive.
Results: Nut coke recovery increased by 18 tons per shift. Payback period on the screen was 4 months based on recovered product value.

Petroleum Coke Calcining – Final Screening

Challenge: High moisture content (810%) in calcined petroleum coke was blinding woven wire screens, causing 30% downtime for manual cleaning.
Solution: Installed a CS1536 with antiblinding polyurethane panels and a heated deck option.
Results: Screen blinding eliminated. Uptime increased to 98%. Maintenance labor reduced by 200 hours per year.

FAQ

Q: Can this screen handle wet coke with 12% moisture?
A: Yes, with the optional heated deck and polyurethane media. Standard units perform best at moisture levels below 8%. Field data shows a 5% efficiency drop at 12% moisture without the heated option.

Q: What is the typical lead time for a wholesale order?
A: Standard CS series units ship in 68 weeks. Custom HD series require 1014 weeks. Rush orders (4 weeks) are available with a 15% expedite fee.

Q: How does this screen compare to a banana screen for coke?
A: For straight sizing of coke, this linear motion screen provides 9295% efficiency. Banana screens offer higher capacity per deck area but are 2530% more expensive. For most coke applications, the linear motion design offers better costtoperformance ratio.

Q: What warranty covers the exciter gearbox?
A: The exciter gearbox carries a 24month warranty against manufacturing defects. Oil seals are considered consumable and are covered for 12 months. Industry testing shows a mean time between rebuilds of 18,000 hours.

Q: Can I retrofit my existing screen with your polyurethane panels?
A: Yes, we offer custom panel sizing for most major OEM screen decks. Provide your deck dimensions and current media type for a compatibility assessment. Retrofitting typically costs 30% less than a full screen replacement.

Q: What is the ROI timeline for upgrading from a standard screen?
A: Based on reduced fines generation (3% improvement) and lower maintenance costs, typical payback is 814 months. A plant processing 200 TPH of coke at $150/ton sees annual savings of $180,000 from reduced fines loss alone.

Q: Do you provide installation supervision?
A: Yes, our Premium service package includes 5 days of onsite installation supervision. Standard packages include a detailed installation manual and remote video support.
