1. PAINPOINT DRIVEN OPENING

Are you managing persistent bottlenecks and escalating costs in your screening operations? For plant managers and engineering contractors, inefficient particle separation directly impacts throughput, product quality, and the bottom line. Common challenges with conventional vibration screens include:

Excessive Downtime: Frequent screen cloth changes due to premature wear or blinding halt production lines. Unplanned maintenance can cost thousands per hour in lost output.
Inconsistent Product Quality: Inadequate separation efficiency leads to undersize contamination or valuable product loss in oversize streams, compromising final spec and revenue.
High Operational Costs: Excessive energy consumption from inefficient drive systems and the laborintensive nature of routine maintenance steadily erode profit margins.
Structural Integrity Concerns: Fatigue failures in the screen body or deck support system from highcycle stress result in catastrophic, costly repairs.

Is your operation sacrificing reliability and profitability due to these recurring issues? The solution lies not just in a screen, but in a precisionengineered system designed for industrial endurance.

2. PRODUCT OVERVIEW

The OEM Coke Vibration Screen is a heavyduty, linear motion screening machine engineered specifically for the rigorous demands of coke classification in metallurgical and chemical processing plants. Its design focuses on accurate size separation of hot, abrasive coke particles.

Operational Workflow:
1. Feed & Distribution: Sized coke is fed onto the robust feed box, which evenly distributes material across the full width of the screening deck.
2. Stratified Separation: The dual counterrotating vibrator assembly generates a linear throwing motion, stratifying material. Fines pass through the precisely sized screen panel apertures.
3. Efficient Discharge: Correctly sized oversize and undersize fractions are conveyed along the deck and discharged via separate chutes for downstream processing.

Application Scope: Primary and secondary sizing of metallurgical coke, coke breeze separation, and similar applications involving hot, abrasive granular materials.

Limitations: Not designed for sticky, moist materials that cause severe blinding, or for extremely fine separations below approximately 1mm without specialized deck configurations.
