The Chinese Coke Vibration Screen represents a critical piece of processing equipment within the global metallurgical and carbon industries. Engineered for the rigorous dry classification of calcined petroleum coke (CPC), also known as “green” or “anode” coke, this machinery is pivotal in ensuring the precise particle size distribution required for aluminum smelting anodes and other carbon products. Modern Chinese manufacturers have evolved from basic replicators to innovators, offering screens that combine robust construction, advanced vibration mechanics, and intelligent control systems. This datasheet provides a comprehensive technical overview of the design principles, operational parameters, performance characteristics, and application-specific configurations of high-performance Coke Vibration Screens originating from China’s specialized heavy machinery sector.
Calcined petroleum coke, a key raw material with high carbon content and low impurity levels, must be precisely sized before being used in anode paste or electrode production. Oversized or undersized particles negatively impact anode density, electrical conductivity, and consumption rates in electrolytic cells. The Chinese Coke Vibration Screen is designed explicitly for this high-abrasion, high-capacity screening task.

| \ *Weight(Approx.)**~4500 kg~7500 kg~11000 kg~15000 kg |
\ \ \ Note:\ \ Specifics vary by manufacturer.\ \ Capacities are based on bulk density of CPC (~0.\ \ \ \ \ \ \ \ \ \ .9 t/m³),\ normal moisture,\ .and defined separation efficiency.
.5.\ .High Efficiency &\ .Precision:*
.Optimized kinematics ensure proper material stratification &\ .rapid conveyance across the deck,\ .achieving screening efficiencies up to\
.90-\ .95% for most size ranges.\
.Minimized pegging &\ .blinding,\ especially with PU panels.
.5.\ .Robustness &\ .Durability:*
.Heavy-duty construction withstands continuous impact &\ abrasion from sharp,\ hard coke.
.High-quality vibrator bearings (\ e.g., SKF,\ FAG,\ NSK)\ with L10 life calculations exceeding\
.20,\000 hours under rated load.
.Easy-replaceable wear parts minimize downtime.*
.5.\ .Energy Efficiency &\ Low Noise:*
.Efficient direct-drive systems &\ optimized mass balance reduce specific power consumption.
.Enclosed design &\ use of polyurethane dampens operational noise to <85 dB(A)\ at\
.1 meter.*
**.5.\ Intelligent Monitoring (\ Optional):**
.Modern units can be equipped with bearing temperature sensors,\ vibration transducers,\ &
motor current monitors connected to PLC systems for predictive maintenance.*
.5.\ Customization Flexibility:*
.Chinese manufacturers excel at providing application-engineered solutions:\ adjustable deck angles,\ special feed boxes,\ multiple discharge chutes,\ explosion-proof designs for dusty environments,\ &
corrosion-resistant coatings.
.6.\ Foundation &\ Installation:*
A massive concrete foundation with sufficient stiffness &
mass (\ typically\
>\
>\
>\
>\
> mass of screen)\ is mandatory to absorb dynamic loads.*
Installation must ensure levelness; misalignment causes uneven stroke &
premature wear.
.6.\ Operational Protocol:*
Startup must be under no-load conditions.
Feed must be even &
distributed across the full width of the feed box via a conveyor or chute.
The feed rate should be kept within designed capacity to prevent overload &
reduced efficiency.
.6.\ Maintenance Schedule:*
Daily: Visual inspection for loose bolts,
abnormal noise,
& check isolation springs.
Weekly: Inspect screen panel tension &
wear; clean dust buildup.
Monthly: Check vibrator bolt torque; inspect motor alignment &
couplings.
Annually/Bi-Annually: Comprehensive inspection; replace worn liners &
screen panels; regrease or replace vibrator bearings as per service life.
