1. PAINPOINT DRIVEN OPENING

Are your bulk material handling operations compromised by persistent screening inefficiencies? For plant managers and engineering contractors, the performance of a vibration screen directly impacts throughput, product quality, and bottomline profitability. Common challenges include:

Excessive Downtime: Frequent screen cloth changes and bearing failures halt your entire processing line, costing thousands per hour in lost production.
Inconsistent Product Gradation: Poor stratification and blinding lead to offspec material, resulting in product rejection, rework costs, and customer dissatisfaction.
High Maintenance Burden: Designs with numerous lubrication points and complex assemblies demand excessive labor hours for routine servicing.
Energy Inefficiency: Older or poorly designed screens consume disproportionate power for their output, with vibration energy wasted as heat and noise rather than effective material separation.
Structural Fatigue: Inadequate dynamic force management leads to weld cracks and frame failures, demanding major unplanned repairs.

Is your operation seeking a reliable screening solution that maximizes uptime, ensures precise separation, and reduces total cost of ownership? The specification of your core screening equipment is a critical decision.

2. PRODUCT OVERVIEW

A White Label Coke Vibration Screen is a heavyduty industrial screening machine engineered for the precise sizing and scalping of petroleum coke (petcoke) and similar abrasive, dry bulk materials. It utilizes controlled vibratory motion to stratify and separate material by particle size across one or multiple deck surfaces.

Operational Workflow:
1. Feed & Distribution: Raw coke is fed onto the screen’s inlet headbox, which evenly distributes material across the full width of the top deck.
2. Stratification & Separation: HighGforce vibratory motion induces stratification, causing finer particles to descend through the bed to the screen media. Oversize material travels across the deck surface to the discharge end.
3. Sized Product Discharge: Correctly sized particles pass through the screen cloth apertures (undersize), while oversize continues over the decks. Multiple decks allow for simultaneous production of several graded fractions.

Application Scope: Primary sizing (scalping) and secondary sizing/dedusting of petroleum coke (calcined or green), metallurgical coke, anodegrade coke, and other granular minerals with similar characteristics.

Key Limitations: Not designed for wet screening applications, sticky materials, or extremely fine (<1mm) separations without specialized screen media. Maximum feed size is constrained by deck aperture and machine design.
