Product Overview
This drum test equipment is an industrial-grade testing apparatus engineered specifically to evaluate the mechanical strength, shatter resistance, and abrasion degradation of metallurgical coke. Operating on the proven tumbling principle, the machine simulates the severe mechanical stresses that lump coke experiences during material handling, chute transfers, and descent through industrial blast furnaces. By inducing controlled collisions between coke particles and the reinforced drum cylinder, this equipment enables precise determination of standard crushing resistance indices (M40 and M25) and the abrasion resistance index (M10).
Built to fulfill the rigorous demands of metallurgical quality assurance, this testing unit serves as an essential analytical tool for coke-making plants, ironmaking facilities, commercial commodity inspection centers, and research institutes. It provides continuous verification of lump integrity, helping furnace operators prevent bed compaction, preserve gas permeability, and optimize fuel rates. The system accommodates standardized test charges, processing raw metallurgical samples into distinct grain fractions for post-tumbling sieve classification.
Constructed with a heavy-duty welded steel framework and high-torque direct drive, the equipment delivers unwavering rotational stability under unbalanced bulk loads. Strict adherence to standardized rotational velocities and drum geometry ensures reproducible test cycles across shifts. Operators can rely on this rugged machine for day-in, day-out verification of raw materials, ensuring that only blast-furnace-compliant coke enters high-value smelting operations.
Detail & Parts
Key Features
- Standard-Compliant Drum Geometry: Fabricated with an internal diameter of 1000 mm and a working length of 1000 mm, the cylindrical chamber perfectly fulfills GB/T 2006-2008 specifications to guarantee internationally comparable kinetic drop trajectories and impact forces.
- Precision Rotational Velocity: Powered by an efficient 1.5 kW motor, the drive assembly maintains a constant rotational speed of 25 r/min, eliminating velocity drift and ensuring steady centrifugal forces during the entire test duration.
- Automated Preset Revolution Control: An integrated digital revolution counter automatically shuts down the system precisely upon reaching the preset target of 100 revolutions, eliminating operator timing error and protecting test reproducibility.
- Heavy-Gauge Abrasion-Resistant Shell: The drum shell is rolled from thick structural carbon steel designed to withstand extreme abrasive wear from high-hardness coke lumps, preventing shell deformation over thousands of tumbling cycles.
- Balanced Rotational Assembly: The drum body undergoes rigorous static and dynamic balancing to eliminate vibration and shaft strain, providing smooth operational stability even when carrying unevenly distributed internal material charges.
- Secure Dual-Clamping Inspection Hatch: Features a wide loading and discharging door fitted with robust perimeter sealing and quick-action mechanical clamps to prevent hazardous dust escape while facilitating rapid sample loading and complete sample recovery.
- Heavy-Duty Rigid Support Structure: The drum rests on heavy structural I-beam and channel supports, anchoring the rotating mass securely to the floor and isolating vibrational harmonics from adjacent laboratory equipment.
- Industrial 380V Electrical Platform: Built with three-phase industrial electrical components, overload protection circuitry, and an intuitive control panel, this unit delivers fail-safe continuous operation in challenging laboratory and pilot plant environments.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Blast Furnace Feedstock Screening | Routine mechanical screening of incoming coke batches to determine M40 and M25 shatter indices prior to furnace charging. | Prevents blast furnace permeability loss, reduces hanging or slipping events, and stabilizes ironmaking production rates. |
| Coking Plant Process Control | In-line quality monitoring of coke batches exiting quench towers to evaluate coal blend formulas and coking carbonization schedules. | Allows immediate tuning of coal blending formulations and coking times to minimize raw material expenses while maintaining target physical strength. |
| Commercial Commodity Inspection | Third-party verification of export and import metallurgical coke quality at port terminals, rail heads, and trading hubs. | Generates undisputed, standard-compliant mechanical durability data for contractual settlements and commercial trade certifications. |
| Metallurgical Research & Development | Laboratory assessment of non-recovery coking, biomass briquette co-coking, and new binder agents under standardized abrasion stresses. | Delivers precise baseline data for academic research, carbon emissions reduction initiatives, and novel metallurgical coke development. |
| Foundry Coke Evaluation | Mechanical durability testing of large-size cupola foundry coke to verify resistance to crushing under deep bed static loads. | Guarantees that cupola charges retain interstitial spacing for optimal combustion air distribution and efficient iron melting temperatures. |
| Carbon Anode Material Verification | Mechanical impact testing of formed carbon blocks, graphite electrode stock, and prebaked anode materials for aluminum smelting. | Confirms fracture toughness and resistance to spalling under mechanical handling prior to electrolytic cell installation. |
