1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Is your coke handling and classification process a source of chronic downtime and cost overruns? Для руководителей предприятий, контролирующих сортировку кокса, common operational challenges include:
Ослепление & Переноситься: Отлично, липкие частицы кокса, while oversized material carries over into finished product bins, compromising quality and forcing manual intervention.
Чрезмерные циклы технического обслуживания: The abrasive nature of coke accelerates wear on screen panels, подшипники, и возбудители, что приводит к частым, unplanned shutdowns for parts replacement.
Неэффективное отделение мелочи: Inconsistent vibration patterns fail to properly separate breeze from nut coke, resulting in product specification misses and lost revenue from misclassified material.
Структурная усталость & Отказ: Highcycle operations under heavy load lead to weld cracks and structural failures in the screen body, creating major capital repair events.

These issues translate directly into quantifiable losses: hours of lost production per month, рост запасов запасных частей, and inconsistent product quality affecting customer contracts. How do you achieve reliable separation with minimal maintenance? The answer lies in specifying a purposeengineered Вибрационный грохот кокса.

2. ОБЗОР ПРОДУКТА

А Вибрационный грохот кокса это мощная промышленная сортировочная машина, предназначенная для снятия скальпа, калибровка, и обеспыливание металлургического и нефтяного кокса. Its core function is to separate bulk coke into precise fractions (например, blast furnace nut coke, foundry coke, ветер) using controlled vibratory motion.

Операционный рабочий процесс:
1. Кормить & Распределение: Bulk coke is fed onto the screen’s robust feed box, which evenly distributes material across the full width of the first screening deck.
2. Стратификация & Разделение: Highintensity vibration stratifies the material; fines pass through upper deck apertures while larger particles travel across the deck surface.
3. Размеры & Увольнять: Multideck configurations allow for sequential sizing. Correctly sized fractions discharge from designated discharge spouts into separate conveyors or bins for downstream processing.

Область применения: Primary sizing of ovendischarged coke, scalpandscreen circuits in byproduct plants, final product grading before shipment, и обеспыливание.

Ограничения: Не предназначен для мокрого просеивания или применения навозной жижи.. Maximum lump size is constrained by feed chute and deck aperture design; typically handles feed sizes up to 300mm.

Integrated Steel Plant – Blast Furnace Feed Circuit

Challenge A major steel producer faced persistent blinding on their primary coke screens during humid months.This caused nut coke contamination with excessive fines (6мм), risking blast furnace permeability,and required biweekly manual cleaning halting the line.Their existing screens' welded decks were prone to cracking,causing further unplanned downtime.Solution Implementation of two new heavyduty Coke Vibration Screens featuring sealed balltray antiblinding systems,a bolted modular deck structure,and polyurethane panels.The installation was timed with a scheduled furnace reline.The Results Screening efficiency for 6mm material stabilized at ≥96%.Manual cleaning was eliminated.Product consistency improved,directly contributing to stable furnace operation.Maintenance downtime related to screening was reduced by an estimated75%,and no structural repairs have been required in three years of operation.

Petroleum Coke Processing Terminal

Challenge At a bulk export terminal handling calcined petroleum coke,vibrationinduced fatigue was causing catastrophic failures in screen support structures every1418 months.Dust emission at transfer points also exceeded new local regulations,due to poor sealing on old equipment.Solution Procurement of customengineered Coke Vibration Screens with reinforced,twinbeam base frames designed for higher Gforces,and fully enclosed,dusttight bodies integrated with the plant's extraction system.The Results Structural integrity has been maintained beyond36 months with no signs of stress fatigue.Dust emissions at the screening station measured below permitted levels,satisfying compliance audits.The terminal reported a22% reduction in total costofownership per ton screened over two years due to lower repair costs
