1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Is your coke handling operation plagued by inconsistent product quality, начисление чрезмерных штрафов, и незапланированные остановки технического обслуживания? Для руководителей предприятий, контролирующих сортировку кокса, common challenges directly impact profitability and throughput. Вы испытываете:

Ослепление & Переноситься: Moisture or sticky fines blinding screen decks, causing product contamination and forcing premature shutdowns for manual cleaning.
Чрезмерное время простоя: Frequent bearing failures or structural fatigue on vibrating screens leading to 2040 hours of unscheduled downtime annually for repairs and parts replacement.
Высокие затраты на техническое обслуживание: The abrasive nature of coke accelerating wear on screen panels, палубы, и возбудители, resulting in high consumable costs and labor for changeouts.
Inefficient Sizing: Inconsistent feed rates or improper vibration dynamics producing offspec material, leading to customer rejections or reprocessing costs.

Основной вопрос: как можно добиться точного, reliable coke classification while maximizing equipment uptime and minimizing total cost of ownership? The answer lies in selecting a purposeengineered Вибрационный грохот кокса.

2. ОБЗОР ПРОДУКТА

А Вибрационный грохот кокса is a heavyduty industrial screening machine designed for the dry separation of metallurgical coke into precise size fractions—typically nut coke, ветер, and lump coke—after the quenching process. Its robust construction handles highly abrasive materials while resisting corrosion from residual moisture.

Операционный рабочий процесс:
1. Контролируемая подача: Quenched coke is conveyed onto the screen’s feed box, distributing material evenly across the full width of the top deck.
2. HighIntensity Separation: A dualvibrator mechanism imparts a linear or elliptical motion, stratifying material and propelling particles across the screen cloths.
3. Точный размер: Oversize material travels across the top deck apertures, while correctly sized particles pass through to lower decks for further fractionation.
4. Увольнять & Транспортировка: Separated fractions discharge via dedicated chutes onto designated conveyors for stockpiling or direct feed to blast furnaces.

Область применения & Ограничения:
Объем: Ideal for sinter plants, системы загрузки доменной печи, and foundry operations requiring strict size control (например, 2540mm nut coke). Effective for hot or cold coke screening postquenching.
Ограничения: Не предназначены для процессов мокрого просеивания или в качестве замены сит для скальпирования, обрабатывающих чрезвычайно крупные (+300мм) feedstock without prior crushing. Performance is contingent on proper installation on a structurally adequate support base.
