1. PAINPOINT DRIVEN OPENING

Is your coke handling operation plagued by inefficient fines separation, excessive maintenance downtime, and environmental compliance headaches? Traditional screening methods for petroleum coke and metallurgical coke often struggle with high moisture content, leading to blinding, reduced throughput, and inconsistent product grading. This results in lost revenue from offspec material, high energy consumption from downstream processing of unscreened coke, and escalating costs for screen media replacement and manual cleaning. Are you facing challenges with dust emission control, noise levels exceeding site limits, or the constant battle against abrasive wear that shortens equipment life? These operational inefficiencies directly impact your plant's profitability and environmental standing. The question becomes: how can you achieve precise particle separation for coke while simultaneously reducing operational costs and improving your site's environmental footprint?

2. PRODUCT OVERVIEW

The EcoFriendly Coke Vibration Screen is a highcapacity, linear motion screening machine engineered for the dry classification of petroleum and metallurgical coke. It is designed to separate coke fines from the main product stream or to grade coke into multiple fractions with high accuracy and minimal waste.

Operational Workflow:
1. Controlled Feed: Sized coke is fed onto the screen via a regulated feed chute or conveyor.
2. Efficient Stratification: HighGforce linear vibration stratifies material rapidly, forcing fines to contact the screen media.
3. Precise Separation: Sized apertures on robust screen panels allow undersize material to pass through while oversize travels along the deck.
4. Clean Discharge: Separated fractions are discharged into distinct chutes for further processing or stockpiling.
5. Integrated Containment: The fully enclosed design captures dust at source throughout the process.

Application Scope: Primary sizing of green or calcined petroleum coke (GPC/CPC), metallurgical coke screening at battery or quenching stations, prescreening before crushing circuits.
Limitations: Not designed as a dewatering screen for slurry applications; optimal performance requires feed moisture typically below 8% (subject to particle size distribution).

3. CORE FEATURES

Enclosed DustTight Design | Technical Basis: Sealed deck covers with maintenance access ports and flanged connections for dust extraction systems | Operational Benefit: Contains dust at source, ensuring compliance with workplace air quality standards (e.g., OSHA, ATEX zones) and reducing product loss | ROI Impact: Eliminates costs associated with secondary dust collection structures and reduces cleanup labor.

LowNoise Vibration Mechanism | Technical Basis: Balanced eccentric shaft drive with rubber shear mounts and sounddampening enclosures | Operational Benefit: Reduces operational noise to below 85 dB(A) at 1 meter, facilitating easier communication and meeting strict site regulations | ROI Impact: Minimizes risk of regulatory penalties and reduces longterm costs for operator hearing protection programs.

AbrasionResistant Deck System | Technical Basis: Modular polyurethane or rubberclad steel screen panels with tensioning system | Operational Benefit: Withstands highly abrasive coke particles, extends media life by up to 3x compared to woven wire, and resists blinding from moist fines | ROI Impact: Lowers total cost of ownership through reduced spare parts inventory and less frequent changeout downtime.

EnergyEfficient Drive Configuration | Technical Basis: Directdrive twin vibrator motors with controlled startstop technology | Operational Benefit: Provides consistent linear motion with lower starting amperage draw compared to bruteforce designs | ROI Impact: Reduces peak energy demand and yields measurable savings on power consumption per ton of material processed.

Minimal Maintenance Architecture | Technical Basis: Centralized lubrication points for bearings, quickrelease deck clamps, and easily accessible motor mounts | Operational Benefit: Enables routine inspection and component replacement in hours instead of shifts | ROI Impact: Increases annual available operating time (AOT) by minimizing planned maintenance windows.

6. APPLICATION SCENARIOS

Metallurgical Coke Plant – Battery RunofOven Screening

Challenge: A steel plant needed to screen hot runofoven coke while controlling immense dust plumes that created environmental noncompliance issues and hazardous working conditions near the battery. Their existing screens had short media life due to heat and abrasion.
Solution: Implementation of a fully enclosed EcoFriendly Coke Vibration Screen equipped with heatresistant seals and specialized screen panels rated for elevated temperatures.
Results: Dust emissions at the discharge point were contained by over 70%, bringing the operation within permit limits. Screen panel replacement intervals extended from four months to over fourteen months.

Petroleum Coke Calcining Plant – Green Coke PreScreening

Challenge: A calciner was experiencing frequent downstream crusher blockages due to excessive fines in feed stockpile reclaim circuits. Their open vibrating screens were also a major source of airborne dust.
Solution: Installation of a twodeck EcoFriendly Coke Vibration Screen ahead of the crusher circuit in an enclosed transfer house.
Results: Fines (6mm) removal efficiency exceeded 92%, eliminating crusher blockages and increasing throughput stability. The integrated dust control system allowed recapture of valuable fine material as a saleable product stream.
