1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Ваша операция по сортировке кокса страдает от постоянных, дорогостоящая неэффективность? Для руководителей заводов и инженерных подрядчиков, the challenges of screening metallurgical coke directly impact throughput, качество продукции, и чистая рентабельность. Общие болевые точки включают в себя:

Чрезмерное начисление штрафов: Aggressive or poorly tuned vibration can degrade premium coke into undersized fines, reducing valuable product yield and creating excess waste material.
Ослепление & Переноситься: Sticky coke breeze and moisture cause screen mesh blinding, while insufficient vibration leads to material carryover. Both scenarios force frequent stoppages for manual cleaning and result in inconsistent size fractions.
Большие простои при обслуживании: Constant, heavyduty operation leads to premature failure of screen decks, источники, and vibrator motors. Unplanned downtime for repairs disrupts blast furnace feed schedules.
Inefficient Capacity Management: A singlescreen setup cannot adapt to varying feed rates or different size specifications, creating bottlenecks in highvolume operations.

Are you facing rising operational costs due to screen maintenance and product loss? Is your current equipment failing to deliver consistent grade separation under full load? The solution requires a purposeengineered approach to material handling.

2. ОБЗОР ПРОДУКТА

The Coke Vibration Screen is a heavyduty industrial screening machine designed for the precise separation of metallurgical coke into defined size fractions (например, доменный кокс, ореховый кокс). It operates on the principle of applied vibration to stratify and convey material across a screening surface.

Операционный рабочий процесс:
1. Контролируемая подача: Sized coke from the crusher is evenly distributed onto the inlet end of the vibrating screen deck via a feed box or conveyor.
2. Стратификация & Разделение: Высокая частота, lowamplitude vibration fluidizes the bed of material. Smaller particles sift through the apertures of the screen cloth (панель), while oversized particles travel across the deck surface.
3. Эффективная разрядка: Correctly sized material (проходы) discharges from a lower outlet chute. Негабаритный материал (overs) travels along the deck length and discharges from the end, directed to downstream processes.

Область применения: Primary and secondary sizing of metallurgical coke in coke plants, сталелитейные заводы, and ferroalloy facilities. Подходит для горячего или холодного отсева кокса..

Ограничения: Not designed for wet screening or slurries without significant modification. Maximum lump size is constrained by feed chute and deck design specifications.
