1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

¿Su operación de manipulación de coque está plagada de cuellos de botella persistentes?, costos de mantenimiento excesivos, y calidad del producto inconsistente? Para gerentes de planta que supervisan el cribado de coque, Los desafíos comunes impactan directamente en el resultado final.:
Cegador & Continuar: Cubiertas de criba ciega para humedad y partículas finas, reduciendo el área de detección efectiva y forzando el arrastre de material. This contaminates product grades and creates costly rehandling.
Tiempo de inactividad excesivo & Mantenimiento: Standard vibrators and bearings fail under continuous heavy loads, provocando paradas no planificadas. Industry data indicates some operations lose over 15% of available runtime to screen maintenance.
Fatiga estructural & Frame Cracking: The abrasive nature of coke and highcycle vibration induce metal fatigue in inadequately designed frames, resulting in catastrophic failures and expensive structural repairs.
Separación de multas ineficiente: Inconsistent vibration patterns fail to properly separate breeze from nut coke, leaving potential revenue unrealized and causing downstream process issues.

Are you searching for a screening solution engineered to withstand the specific demands of coke classification with higher availability and lower total cost of ownership?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO: Criba vibratoria de coque de servicio pesado

The HeavyDuty Coke Vibration Screen is a bruteforce linear motion screening machine engineered for the primary sizing, especulación, and dedusting of metallurgical and petroleum coke. Its design prioritizes structural integrity and material stratification to handle hightonnage, abrasive applications.

Flujo de trabajo operativo:
1. Alimentación controlada: Coke is directed onto the robust feed box, which distributes material evenly across the full width of the primary screen deck.
2. HighEnergy Stratification: A dualshaft, synchronized vibrator assembly generates a linear throwing motion. This action aggressively stratifies the material bed, forcing fines downward for rapid separation.
3. Tamaño preciso: Sized fractions pass through defined deck apertures (typically wire mesh or polyurethane panels). Oversize material travels over the deck surface to a designated discharge spout.
4. Protected Discharge: Sized fractions are discharged through sealed discharge spouts designed to minimize dust emission and spillage.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for primary screening of hot or cold coke (coca de nuez, brisa) in coke plants, acerías, e instalaciones de producción de ánodos. Capable of handling feed sizes typically from 080mm.
Limitaciones: Not designed as a replacement for finewet screening or dewatering applications. Maximum efficiency is achieved with controlled feed rates as per designed capacity.
