1. PAINPOINT DRIVEN OPENING

Are your coke screening operations plagued by persistent inefficiencies that directly impact your bottom line? Common challenges include:

Excessive Downtime: Frequent screen cloth blinding and premature wear from abrasive coke fines, leading to unscheduled maintenance stops and lost production hours.
Inconsistent Product Grading: Inefficient separation resulting in offspec material—oversize particles contaminating the nut coke fraction or excessive fines in the blast furnace feedstock—compromising downstream process efficiency.
High Operational Costs: Constant replacement of screen decks, excessive energy consumption from inefficient vibration mechanisms, and high labor costs for manual clearing and maintenance.
Structural Integrity Concerns: Vibration transmission to support structures causing fatigue cracks and foundation issues, creating longterm plant safety and capital expenditure risks.
Dust Emission & Spillage: Poor sealing and excessive vibration exacerbate housekeeping issues, creating environmental control challenges and product loss.

Is your current screening solution a source of recurring cost and reliability headaches? What would a 2030% reduction in maintenance intervals and a 15% improvement in screening efficiency mean for your annual operational budget?

2. PRODUCT OVERVIEW

The Coke Vibration Screen is a heavyduty, highcapacity screening machine engineered for the precise size classification of metallurgical coke. It separates crushed coke into defined fractions—such as blast furnace coke, nut coke, and breeze—critical for optimal furnace operation.

Operational Workflow:
1. Feed Introduction: Crushed coke is uniformly distributed onto the feed box of the inclined screen deck(s).
2. Vibratory Separation: A highefficiency vibrator assembly imparts a linear or elliptical motion, stratifying material and propelling it across the screening surface.
3. ​​SizeBased Stratification: Particles smaller than the screen aperture fall through as undersize, while larger particles travel across the deck to discharge as oversize.
4. Fraction Discharge: Separated material streams are discharged via dedicated chutes into designated collection hoppers or conveyors for further processing or shipment.

Application Scope & Limitations:
Scope: Ideal for primary sizing of hot or cold metallurgical coke in coke plants, steel mills, and bulk handling terminals. Effective for capacities ranging from 200 to 1500+ tons per hour.
Limitations: Not designed for sticky materials without pretreatment (e.g., preheating). Performance is contingent on proper feed rate control and consistent moisture content management.
