Your Screening Operation Is Losing Profit—Here's the Data
Every ton of coke that passes through an undersized or poorly matched vibration screen costs your plant in three measurable ways: producto rechazado (arriba a 8% of throughput lost to offspec material), tiempo de inactividad no planificado (promedio 14 hours per month for screen deck changes on inferior units), y excessive power consumption (older screens draw 30–40% more energy per ton processed). Plant managers report that blinding and pegging on coke fines alone can reduce effective screening area by 25% within the first 200 horas de funcionamiento.
Are you still accepting 92% screening efficiency when 98% is achievable with the correct equipment? Is your current screen supplier delivering replacement parts within 48 horas, or are you stockpiling inventory because lead times stretch beyond three weeks? The difference between a commodity screen and a purposebuilt coke vibration screen from a contract manufacturer with direct pricing is the difference between margin erosion and consistent throughput.
Descripción general del producto: Criba vibratoria de coque de servicio pesado
Este equipo es un linearmotion, criba vibratoria multiplataforma engineered specifically for coke handling—from green coke dewatering to calcined coke sizing. The operational workflow follows five stages:
1. Feed Distribution – Material enters via a flared feed box with replaceable wear liners, spreading across the full width of the screen deck to prevent material segregation.
2. Estratificación – Linear vibration (6.3–8.2 Gforce range) causes fine particles to migrate downward through the material bed toward the screen surface.
3. Separación – Material passes through woven wire or polyurethane screen panels (custom aperture sizes from 0.5 mm a 150 milímetros) on 1–4 decks.
4. Oversize Discharge – Material retained on each deck exits through dedicated chutes, with impactabsorbing rubber liners at all transfer points.
5. Undersize Collection – Fines pass through to a common discharge or individual collection hoppers, depending on plant configuration.
Ámbito de aplicación: Suitable for coke breeze screening, coke dewatering, coke crushing circuits, and final product sizing in steel mills, aluminum smelters, and calcining facilities. Limitaciones: Not designed for materials exceeding 150°C continuous operating temperature without hightemperature bearing upgrades; not recommended for materials with more than 15% moisture content without heated deck options.

Preguntas frecuentes
q: How does this screen handle the abrasive nature of calcined coke compared to standard aggregate screens?
A: Standard aggregate screens use 6 mm mild steel liners and standard bearings. Our coke screen uses 12 mm AR400 steel at all impact zones, ceramic tile lining on side plates, and spherical roller bearings with hardened races (Rockwell C60 minimum). Datos de campo de 18 installations shows side plate wear rates of 0.3 mm per year versus 2.1 mm per year on standard screens.
q: What is the maximum moisture content this screen can handle without blinding?
A: With the standard polyurethane panels and selfcleaning ball deck, the screen maintains 95%+ open area at up to 12% humedad. For moisture content between 12% y 18%, we recommend the heated deck option (electric resistance heating elements beneath the screen surface). Arriba 18% humedad, a dewatering screen with slotted panels is more appropriate.
q: Can this screen be retrofitted into an existing structure without modifying the support steel?
A: Sí, in most cases. Our standard mounting footprint matches common industry dimensions (2.4 m × 6.0 metro, 3.0 m × 7.2 metro). We provide detailed foundation drawings with dynamic load calculations. For nonstandard installations, we offer custom base frame adapters at an additional cost of $3,500–$6,000, dependiendo de la complejidad.
q: What is the typical delivery time for replacement screen panels?
A: Standard polyurethane panels (all aperture sizes) ship within 48 hours from our regional warehouses. Custom aperture sizes require 10–14 working days. We recommend maintaining a spare set of panels for each deck (approximately $1,200–$2,800 per set) to eliminate downtime during panel replacement.
q: How does the pricing compare to OEM screens from major manufacturers?
A: Our base pricing is 25–35% lower than comparable models from major OEMs (p.ej., Raíces, Sandvik, terex). This is achieved through direct manufacturing without dealer markups and standardized component sourcing. Total cost of ownership over 5 years is typically 30–40% lower due to reduced maintenance requirements and longer component life.
q: ¿Qué cobertura de garantía se proporciona?, and what is excluded?
A: Standard warranty covers manufacturing defects in materials and workmanship for 12 meses desde la puesta en servicio o 18 meses desde el envío, lo que ocurra primero. Excluded items: piezas de desgaste (paneles de pantalla, revestimientos, sellos), damage from improper installation, operation outside specified parameters, and modifications without written approval. Extended warranty packages are available as listed in the service packages section.
q: Can this screen be integrated with existing PLC and SCADA systems?
A: Sí. The vibration monitoring system outputs 4–20 mA signals for vibration amplitude, temperatura del rodamiento, and motor current. Modbus RTU (RS485) communication is standard. We provide full register maps and can integrate with AllenBradley, siemens, and Schneider Electric platforms. Custom protocol integration (Profibus, DeviceNet, Ethernet/IP) is available at an additional cost of $1,800–$3,200.
