1. PAINPOINT DRIVE NOLEING

Таны кокстой харьцах үйл ажиллагаа байнгын түгжрэл, засвар үйлчилгээний зардал нэмэгдэж байгаатай холбоотой юу?? Үйлдвэрийн менежерүүд болон инженерийн гүйцэтгэгчид, үр ашиггүй скрининг нь эцсийн дүнд шууд нөлөөлдөг. Нийтлэг бэрхшээлүүд орно:

Нүд сохлох & Тээвэрлэлт: Fine, sticky coke particles blind screen decks, reducing effective screening area and forcing material carryover into the wrong product streams. This contaminates product grades and necessitates costly reprocessing.
Хэт их зогсолт & Дэмжлэгэ: Traditional screens with complex drive mechanisms and numerous moving parts require frequent lubrication, belt changes, and bearing replacements, төлөвлөгдөөгүй зогсолтод хүргэдэг.
Эрчим хүчний өндөр хэрэглээ: Inefficient vibratory systems operate at constant high power, regardless of feed conditions, wasting significant energy over thousands of operational hours.
Бүтцийн ядаргаа & Failure: The intense, reciprocating forces from conventional exciters transmit high stress to the screen body and support structure, leading to weld cracks, side plate failures, and shortened equipment lifespan.

Are you seeking a coke vibration screen solution engineered to minimize these operational burdens while maximizing throughput and product consistency?

2. БҮТЭЭГДЭХҮҮНИЙ ТОЙМ

Our engineered service provides heavyduty Coke Vibration Screens, specifically designed for the abrasive and demanding environment of coke handling in steel production, анодын үйлдвэрүүд, and calcining operations.

Үйл ажиллагааны ажлын урсгал:
1. Тэжээл & Хувиарилалт: Sized coke from crushers or ovens is fed onto the screen’s robust feed box for even distribution across the full width of the screening deck.
2. HighEfficiency Stratification: Хүчирхэг, linear vibratory motion stratifies the material bed, forcing fines downward through the screen media while conveying oversize toward the discharge end.
3. Precise Separation: Multiple deck configurations allow for precise separation into two or three distinct product streams (жишээ нь e., nut coke from breeze).
4. Хяналттай ялгадас: Separated fractions are discharged via dedicated chutes for downstream processing or stockpiling.

Хэрэглээний хамрах хүрээ: Primary and secondary screening of metallurgical (met) карк, petroleum coke (петкок), and calcined coke in sizing ranges typically from 080mm.

Хувьсгал: Not designed for extremely fine classification (<1mm) which requires specialized fine screening technology, or for materials at temperatures exceeding 250°C without specific design adaptations.
