Product Overview
This specialized coke ball grinding machine serves as a critical auxiliary refinement system engineered to maximize sample yield in metallurgical coke testing laboratories. Operating downstream from primary crushing and ball-forming equipment, the unit takes irregularly shaped or out-of-spec coke lumps and mechanically grinds them into precisely calibrated, uniform spherical specimens. By transforming non-conforming pre-crushed coke into compliant test specimens, this system drastically reduces raw material waste and enhances laboratory sample preparation throughput.
Purpose-built for quality inspection centers, blast furnace coke production plants, research institutes, and commercial assay laboratories, the equipment standardizes specimen geometry to satisfy demanding thermal and mechanical test protocols. Its primary role focuses on preparing reliable specimens for high-temperature reactivity and post-reaction strength assessments, where dimensional consistency directly dictates experimental validity. Facilities handling high volumes of hard, abrasive carbon materials rely on this unit to maintain repeatable sample dimensions without operator-dependent variations.
Constructed with heavy-gauge structural steel and high-torque mechanical drive components, this robust grinding system ensures unwavering operational stability under continuous, heavy-duty laboratory conditions. Its closed processing chamber and vibration-damped chassis withstand the abrasive wear inherent to grinding hard metallurgical coke, delivering dependable performance batch after batch. Industrial procurement teams gain an indispensable asset that bridges the gap between rough crushing and rigorous metallurgical compliance.
Key Features
- Targeted Spherical Geometry Refinement: Engineered specifically to smooth out irregular coke fragments from initial shaping stages, turning angular lumps into regular 23 mm to 25 mm spheres required for standardized index evaluations.
- High-Yield Batch Processing: Accommodates a single-batch charge mass of up to 5,000 grams, enabling high-volume specimen preparation while dramatically lowering rejected sample volumes.
- Robust Three-Phase Drive Motor: Powered by a heavy-duty 3.3 kW industrial motor operating on AC 380V/50Hz supply, delivering the steady torque necessary to mill tough, hard-structured metallurgical coke without stalling.
- Optimized Feed Acceptance Range: Accepts raw, pre-processed coke feed sizes of 23 mm and larger, smoothly processing over-dimensioned and angular aggregates down to uniform test spheres.
- Wear-Resistant Processing Chamber: Fabricated with hardened industrial alloys designed to counter the extreme abrasion and surface friction characteristic of carbonaceous coke grinding.
- Enhanced Testing Reproducibility: Uniform spherical specimen production eliminates flow channeling and differential mass-transfer anomalies during subsequent reactivity and strength evaluations.
- Simple Operational Protocol: Streamlined controls and ergonomic loading access allow laboratory technicians to execute batch grinding cycles quickly with minimal manual intervention.
- Enclosed Dust and Debris Containment: Features a tightly sealed processing enclosure that contains carbon particulate matter during intense grinding, maintaining a safe and clean laboratory environment.
