Content Title: Private Label Coke Vibration Screen: CostEffective Sizing for Coal Processing Operations

1. PAINPOINT DRIVEN OPENING

Your coal processing plant faces a constant battle: maintaining consistent product quality while controlling operational costs. Inefficient screening of metallurgical coke and petroleum coke leads to three specific financial drains:

• Oversized product rejection: A 2% increase in oversize material can reduce your saleable yield by 1520 tons per shift, costing upwards of $3,000 daily in lost revenue.
• Blinding and pegging: Standard screens clog within 46 hours of continuous coke processing, forcing unscheduled downtime that averages 45 minutes per shift—equivalent to 180 hours of lost production annually.
• High replacement frequency: Generic screens often fail within 6090 days under the abrasive load of coke, with replacement costs and labor consuming 1218% of your maintenance budget.

Are you paying premium prices for a brand name when the engineering fundamentals are the same? Can you achieve 95% screening efficiency without the 40% price markup of established OEMs?

2. PRODUCT OVERVIEW

The Private Label Coke Vibration Screen is a heavyduty, linearmotion vibrating screen engineered specifically for the classification of metallurgical coke, petroleum coke, and calcined coke. It operates on a dualshaft, counterrotating vibrator assembly that generates a straightline stroke, propelling material across the deck at a controlled velocity.

Operational Workflow:
1. Feed Introduction: Material enters the screen box via a chute, directed to the feed end at a controlled rate (50200 TPH depending on model).
2. Stratification: The linear vibration causes fine particles to migrate to the bottom of the material bed, contacting the screen media.
3. Classification: Particles smaller than the aperture (typically 6mm to 50mm) pass through the screen deck; oversize material travels along the deck.
4. Discharge: Two separate discharge spouts direct undersize and oversize fractions to downstream conveyors or bins.
5. SelfCleaning: The vibratory action, combined with optional ball trays or slotted media, dislodges lodged particles.

Application Scope:

• Primary Use: Dry screening of coke at ambient temperatures (0°C to 50°C).
• Limitations: Not suitable for wet screening of coke (moisture >8% causes rapid blinding). Not designed for hightemperature coke (>200°C) without specialized heatresistant components.

8. FAQ

Q1: Can this Private Label screen match the performance of a major OEM like Schenck or Derrick?
A: Field data from 14 installations shows screening efficiency within 2% of premium OEM models. The core components—vibrator assembly, bearings, and screen media—are sourced from the same ISO 9001 certified factories used by midtier OEMs. The primary difference is the absence of a brand name, not engineering quality.

Q2: What is the typical lead time for a Private Label Coke Vibration Screen?
A: Standard lead time is 46 weeks from order confirmation. Custom configurations (e.g., heated decks, stainless steel) add 23 weeks. This is 50% faster than most branded OEMs due to streamlined supply chain.

Q3: How does the private label branding work?
A: You provide your company logo and color specifications (RAL code). The screen is painted and labeled with your branding. All documentation, including manuals and nameplates, reflects your company name. No manufacturer branding appears on the equipment.

Q4: What is the expected lifespan of the screen media when processing metallurgical coke?
A: With polyurethane panels (60 Shore A hardness), typical lifespan is 1218 months under continuous operation (16 hours/day, 6 days/week). This is comparable to branded polyurethane media. Steel wire cloth lasts 36 months but is not recommended due to rapid abrasion.

Q5: Can this screen handle wet coke or coke with high moisture content?
A: Standard design is for dry screening (moisture <5%). For moisture up to 8%, the optional heated deck system is required. Above 8% moisture, blinding becomes severe, and we recommend a different screening technology (e.g., flipflow screen) for that application.

Q6: What spare parts should I keep in stock for minimal downtime?
A: Recommended initial stock: 1 set of screen media panels (10% of total), 2 bearing assemblies, 1 set of drive belts, 1 set of seals/gaskets. Total cost: approximately $2,500. This covers 90% of common failures.

Q7: Is onsite installation support available, and what does it cost?
A: Yes. The Standard Service Package ($2,500) includes 2 days of onsite commissioning by a factory technician. This covers mechanical alignment, electrical connection verification, and startup tuning. For complex installations (e.g., integrating with existing conveyors), we recommend the Premium Package ($6,000) for 4 days of support.
