Coke Vibration Screen Exporter Specification: A Comprehensive Guide for Global Procurement

In the globalized industrial supply chain, the role of specialized equipment exporters is paramount. For critical sectors like metallurgy, petrochemicals, and fertilizer production, the Coke Vibration Screen is an indispensable piece of equipment for grading, scalping, de-dusting, and dewatering raw and calcined petroleum coke. An exporter’s specification sheet is not merely a list of features; it is a comprehensive technical and commercial passport that defines capability, ensures compatibility, and builds trust across international borders. This detailed guide explores the essential components and considerations of a professional Coke Vibration Screen Exporter Specification.

1. Introduction: The Critical Role of Specifications in Export

An exporter’s specification document serves as the foundational communication tool between the supplier and a global clientele. It transcends basic product data by contextualizing the equipment within international standards, operational environments, and logistical frameworks. For coke processing—where abrasive materials, high temperatures, and continuous operation are norms—a vague specification can lead to catastrophic plant downtime, safety hazards, and costly disputes. Therefore, a world-class specification embodies precision, transparency, and a deep understanding of application engineering.

2. Detailed Equipment Technical Specifications

This core section must be exhaustive and unambiguous.

• Machine Type & Operating Principle: Specify the exact type (e.g., Linear Motion Vibrating Screen, Circular Motion Vibrating Screen, High-Frequency Dewatering Screen). Detail the drive mechanism (Dual Motor Linear Drive, Eccentric Shaft Drive with Counterweights). Explain the motion trajectory (straight-line for scalping/dewatering; circular for efficient grading) and its advantage for coke handling.
• Construction & Materials:
  • Deck Frame: Specify material grade (typically high-tensile carbon steel Q235B/Q345B or stainless steel 304/316 for corrosive environments). Detail construction method (bolted or modular welded design for ease of maintenance/export shipping).
  • Screen Decks & Surfaces: Number of decks (single to multi-deck). Specification must include available screen panel types (woven wire mesh polyurethane panels rubber panels). For coke heavy-duty applications polyurethane panels are often recommended due to their superior abrasion resistance noise reduction clogging prevention.
  • Side Plates & Cross Members: Material thickness reinforcement details to withstand dynamic loads fatigue.
  • Vibrating Unit Assembly: Precise specifications for the exciter assembly including bearing type size brand SKF FAG NTN sealed for life high-temperature grease lubrication. Shaft material diameter.
  • Springs / Isolation System: Type rubber springs coil springs or composite mounts with their stiffness rate damping characteristics ensure effective vibration isolation transmitted to supporting structure.
• Performance & Capacity Data:
  • Screen Box Dimensions: Overall length width depth total screening area per deck square meters).
  • Feed Inlet & Discharge Arrangements: Size configuration of feed box distribute material evenly; details discharge spouts.
  • Processing Capacity: Throughput rates tons per hour must be stated for defined material density typical coke bulk density ~0.8-1.0 t/m³) feed size distribution moisture content.
  • Screening Efficiency: Expected efficiency percentage for target separation sizes under defined conditions.
  • Amplitude & Frequency: Adjustable range amplitude mm) vibration frequency RPM). These are critical parameters determining material stratification conveyance speed.
• Drive & Motor Specifications:
  • Motor Type: Standard electric motor explosion-proof motor required) power rating kW voltage frequency 50Hz 60Hz) protection class IP rating).
  • Power Transmission: Use of flexible coupling direct drive system specifications.
• Operational Parameters:
  • Max Feed Size mm).
  • Operating Temperature Range: Must accommodate hot calcined coke temperatures potentially exceeding 200°C specifying heat-resistant components seals lubricants accordingly).
• Paint & Surface Protection: Full description of surface preparation shot blasting) primer paint system finish coat typically epoxy polyurethane) total dry film thickness DFT) in microns color standard RAL).

3. Design Standards & Certifications

This section validates the exporter’s commitment to quality safety:

• List compliance with international standards: ISO 9001 Quality Management Systems machinery design standards possibly referencing ISO 8524 dynamic testing).
• Conformity with regional directives CE Marking PED Pressure Equipment Directive if applicable).
• Welding standards procedures qualified welders NDT non-destructive testing protocols radiography ultrasonic testing critical welds).
• Electrical component certifications IEC standards.

4. Scope of Supply & Ex-Works Details

Clarity here prevents costly misunderstandings:

• Define exact ex-works supply: The vibrating screen complete with motors starters spring sets all mounting hardware necessary commissioning spares standard tool kit).
• Clearly list exclusions: Freight insurance local taxes installation supervision foundation bolts connecting cables etc.) unless offered as part turnkey package.
• Provide detailed packing specifications: Export-worthy packing in wooden crates seaworthy cases full weather protection desiccant bags internal lashing to prevent transit damage dimensions weight each package facilitating logistics planning).

5. Manufacturing Inspection Testing Protocol FAT)

The exporter must outline quality gates:

• In-process inspections material certificates MTC) dimensional checks.
• Factory Acceptance Test FAT) protocol detail includes:
  • Visual inspection construction paint.
  • No-load test run minimum 4-8 hours continuous operation measurement amplitude frequency at all bearing locations monitoring temperature stability noise levels dB(A)).
  • Dynamic strain testing if specified using accelerometers data acquisition verify structural integrity design loads.
  • Client’s right witness FAT remotely on-site documented with signed report video evidence).

6. After-Sales Support Warranty Terms

Critical for international clients:

• Warranty Period typically 12-18 months from commissioning shipment date covering defects materials workmanship excluding wear consumables screen panels).
• Availability technical documentation operation maintenance manuals parts lists detailed drawings electrical schematics all provided digitally English language).
• Global after-sales service network availability spare parts supply lead time commitment emergency support response times training provisions).

7. Exporter’s Commercial Project Execution Capability

This differentiates a mere supplier from a reliable export partner:

• Experience reference list similar projects specific countries regions particularly in coke steel industries).
• Logistics expertise handling inland freight port procedures export documentation commercial invoice packing list certificate origin bill lading insurance certificates).
• Financial stability ability handle Letters Credit LC other international payment terms efficiently.
