1. PAINPOINT DRIVEN OPENING

Is your coke handling operation losing profitability to inefficient screening? The performance of your coke vibration screen directly impacts product quality, throughput, and maintenance budgets. Common challenges include:

Blinding & Carryover: Moisture and fine coke particles clog screen decks, reducing effective screening area and allowing undersize material into the product stream, compromising quality for blast furnace or foundry use.
Excessive Downtime for Maintenance: Frequent bearing failures, structural fatigue cracks, and deck cloth replacements halt your entire processing line, costing thousands per hour in lost production.
Inconsistent Particle Size Distribution: An unstable or poorly tuned vibration pattern leads to offspec product, resulting in customer rejections or penalties for failing to meet strict size fraction contracts.
High Energy Consumption & Noise: Older or poorly designed screens operate inefficiently, driving up power costs and creating hazardous noise levels that exceed workplace regulations.

Are you seeking a coke vibration screen solution that delivers consistent uptime, protects your product specs, and reduces your total cost of ownership?

2. PRODUCT OVERVIEW: HeavyDuty Coke Classification Screens

Our engineered coke vibration screens are highcapacity, linear motion screening machines designed for the rigorous separation of metallurgical coke and petroleum coke. They classify crushed coke into precise size fractions (e.g., blast furnace nut coke, breeze) critical for downstream processes.

Operational Workflow:
1. Feed: Precrushed coke is uniformly distributed onto the feed box of the vibrating screen.
2. Stratification & Separation: Dual counterrotating exciters generate a linear throwing motion, stratifying material. Oversize particles travel across the top deck(s), while correctly sized material passes through the screen media apertures.
3. Discharge: Separated fractions are discharged via dedicated chutes into designated product bins or conveyors for storage or transport.

Application Scope: Primary and secondary sizing of metallurgical (met) coke and petroleum (pet) coke in steel plants, foundries, anode plants, and bulk handling terminals.

Limitations: Not designed for sticky materials without pretreatment (e.g., drying), extreme abrasionresistant linings are required for highly abrasive petcoke varieties.

3. CORE FEATURES

Modular Deck System | Technical Basis: Boltin panel design with varied aperture media | Operational Benefit: Operators can replace individual worn panels in under 30 minutes versus full deck changeouts. Different wire cloth or polyurethane panels can be configured per deck. | ROI Impact: Reduces screen media downtime by up to 70% and allows rapid adaptation to changing product specifications.

Dual Exciter Drive with Forced Lubrication | Technical Basis: Two synchronized vibrator units generating linear motion; closedloop oil lubrication system. | Operational Benefit: Provides consistent, adjustable amplitude for optimal material travel and separation. Continuous oil filtration extends bearing life significantly. | ROI Impact: Field data shows a 4060% increase in mean time between failures (MTBF) for drive components compared to greaselubricated systems.

DustTight Body Construction | Technical Basis: Continuous welds, sealed inspection covers, and integrated dust shrouds. | Operational Benefit: Contains fine coke breeze within the machine envelope, improving plant air quality and reducing material loss. | ROI Impact: Lowers housekeeping costs and mitigates risk of compliance issues related to particulate emissions.

Optimized Mass & Spring System | Technical Basis: Dynamic modeling ensures the vibrating mass is balanced with correctly rated coil spring or rubber buffer isolators. | Operational Benefit: Minimizes dynamic loads transferred to the support structure, reducing structural fatigue and ambient vibration. | ROI Impact: Eliminates costly structural reinforcements and cuts installation time by allowing placement on existing mezzanines.

HeavyDuty Side Plates & Cross Members | Technical Basis: Highyieldstrength steel plates with stressrelieved welds at highload junctions. | Operational Benefit: Withstands constant highcycle loading from large coke lumps without developing fatigue cracks. | ROI Impact: Extends structural service life beyond 10+ years under continuous operation, protecting your capital investment.

6. APPLICATION SCENARIOS

Integrated Steel Plant Blast Furnace Feed | Challenge: A major steel producer experienced frequent blinding on their primary nut coke screens due to seasonal moisture. This caused excessive carryover of fines into the BF feed bin, disrupting burden permeability.| Solution: Replacement with a new linear motion coke vibration screen featuring heated screen decks and polyurethane antiblinding panels.| Results: Screening efficiency sustained above 93% yearround. Fines generation reduced by an estimated 15%, contributing to more stable blast furnace operation.

Petroleum Coke Calcining Plant| Challenge: An anodegrade petcoke plant needed higher throughput sizing after the calciner but faced severe abrasion wear on screen cloths every 6 weeks.| Solution: Installation of a heavyduty model with specialized tungstencarbide coated wire cloth on top decks and ceramiclined feed boxes.| Results: Screen media life extended to over 24 weeks, aligning with planned quarterly maintenance shutdowns. Throughput increased by 20% due to sustained open aperture area.
