• Testing Date: July 1, 2026
• Location: Guoxin Machinery Assembly Workshop
• Feedstock Material: Metallurgical Coke Breeze / Fine Coke Powder (<3 mm)
• Testing Core: Evaluating binder-to-feedstock homogenization and comparing mechanical roller extrusion against high-pressure hydraulic tablet molding.

1. Feedstock Conditioning: The Art of Homogenization

Unlike biomass or charcoal powder, raw industrial coke breeze possesses zero natural plasticity and high abrasive hardness. Achieving structural integrity in the final briquette requires precise material conditioning inside a heavy-duty wheel muller mixer.

As demonstrated in the processing sequence, our team executed a rigorous three-step batch mixing protocol:

1. Material Feeding: The fine, dry coke breeze was loaded into the mixing pan.
2. Binder Integration: A specialized liquid/powder industrial binder formulation was introduced uniformly onto the spinning bed.
3. Moisture Calibration: Water was systematically metered into the muller to achieve the exact target moisture threshold (typically 8% to 12%), ensuring every micro-grain of coke was coated with the binding agent under heavy roller shear forces.

2. Dual-Route Forming Trials & Mechanical Comparisons

To satisfy different commercial and industrial application requirements, the conditioned coke mixture was split and tested across two distinct forming technologies.

Route A: Continuous Roller Briquetting Press (Ovoid/Pillow Shapes)

For high-capacity, bulk industrial smelting or fuel recycling applications, the roller press provides continuous, high-volume output.

As captured on the production grid, the conditioned coke material was gravity-fed into the counter-rotating pockets of our roller briquetting press. The system delivered perfectly uniform, high-density ovoid (pillow-shaped) coke briquettes. The cleanly discharged briquettes dropped onto the vibrating screen mesh with excellent green strength, ready for immediate industrial curing or drying.

Route B: High-Pressure Hydraulic Molding Machine (Precision Tablets)

For premium combustion, specialized gasification, or high-value chemical applications requiring strict geometry and maximum density, the hydraulic press is the optimal mechanism.

The mechanical sequence and the final product evaluation highlight this high-precision method. Operating under intense vertical hydraulic cylinder pressure, the fine coke breeze was compressed into smooth, ultra-dense circular tablet briquettes.

The molded coke tablets exhibit perfectly defined edges, zero structural layering cracks, and a pristine mechanical finish capable of withstanding severe drop tests without shattering.

4. Key Takeaways from the July 1, 2026 Workshop Verification

• Binder Affinity: The intensive mechanical mulling phase successfully prevented the coke fines from segregating, guaranteeing stable curing properties.
• Zero Die Sticking: Both the hardfaced alloy roller pockets and the hydraulic mirror-finished mold dies achieved clean release dynamics with zero material buildup or crusting.
• Flexible Capacity Layouts: Guoxin can configure complete turnkey production lines featuring either high-capacity roller systems or automated multi-mold hydraulic press layouts based on your facility’s commercial output requirements.
