1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are you managing escalating costs and unpredictable downtime in your coke handling and classification process? Inefficient screening directly impacts your bottom line through lost production, excessive recrushing of onspec material, and premature wear on downstream equipment. Considere estos desafíos operativos comunes:
Cegador & Continuar: Moisture and fine coke particles blind screen decks, reducing effective screening area and forcing oversized material into the product stream, comprometiendo la calidad.
Tiempo de inactividad excesivo por mantenimiento: Conventional screens with highvibration components suffer frequent bearing failures, deck cloth damage, and structural fatigue, leading to unplanned shutdowns.
Baja eficiencia de detección: Inconsistent material flow and poor stratification result in a high percentage of misplaced particles, wasting energy in reprocessing and failing to meet strict size specifications for blast furnace or foundry coke.
Altos costos operativos: The combined effect of frequent part replacements, Alto consumo de energía por tonelada procesada., and laborintensive cleaning protocols erodes profit margins.

Is your current screening solution contributing to these issues? Un diseño específico Criba vibratoria de coque is not merely a piece of equipment; it is a critical process control point designed to resolve these specific challenges.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The HeavyDuty Coke Vibration Screen is a highcapacity, linear motion screening machine engineered for the precise size separation of metallurgical coke (met coke) and petroleum coke (pet coke). It is built to handle abrasive materials while resisting the clogging effects of residual moisture and fines.

Flujo de trabajo operativo:
1. Alimentación controlada: Sized coke from crushers is evenly distributed across the full width of the screen's feed box.
2. Estratificación & Separación: The dualvibrator generated linear motion rapidly stratifies material, forcing fines downward through the screen media while conveying oversize along the deck for discharge.
3. Descarga eficiente: Correctly sized product passes through the deck apertures, while oversize is discharged at the end of the deck for return to crushers or separate stockpiling.

Ámbito de aplicación: Dimensionamiento primario (especulación) of runofoven coke, final product separation for blast furnace (2575milímetros) and foundry cokes, dedusting operations, and pet coke classification.

Limitaciones: Not designed for sticky materials without specialized screen media. Maximum feed size is limited by deck opening and structural design; typically handles lumps up to 300mm.
