Product Overview
This environmental coke drum test machine is engineered to determine the mechanical strength, shatter resistance, and abrasion degradation of metallurgical coke in strict accordance with GB/T 2006-2008 and international testing protocols. By accurately simulating the physical impacts, compressive forces, and abrasive friction experienced by metallurgical fuel during transport, handling, and blast furnace descent, the system provides reliable indices essential for assessing blast furnace fuel performance.
Widely utilized across iron and steel manufacturing complexes, commercial coking plants, third-party inspection laboratories, and metallurgical academic institutions, this testing equipment facilitates standardized quality assurance and raw material grading. It enables process metallurgists and procurement teams to monitor coke friability, predict blast furnace stack permeability, and prevent catastrophic burden degradation during hot metal production.
Constructed with heavy-gauge wear-resistant steel, robust high-torque drive mechanisms, and comprehensive dust suppression engineering, the equipment delivers dependable mechanical stability under aggressive impact cycles. Operational teams achieve uncompromising repeatability, verified acoustic damping, and workplace cleanliness across rigorous, high-throughput testing campaigns in industrial evaluation environments.
Key Features
- Standardized Micum Tumbling Dynamics: Engineered with precision-formed internal lifter plates configured to hoist coke charges past the 90-degree rotational threshold before executing free-fall trajectories, replicating standard drop-shatter impacts and surface abrasion attrition according to GB/T 2006 specifications.
- Full-Enclosure Environmental Dust Containment: Incorporates an advanced sealed outer housing that prevents the escape of airborne particulates and fugitive coke dust during continuous tumbling, protecting technical personnel and meeting strict workplace environmental hygiene standards.
- Automated Revolution and Cycle Control: Features an integrated digital revolution controller programmed to execute exactly 100 drum revolutions within 4 minutes ± 10 seconds, halting operation automatically upon cycle completion to guarantee operator-independent reproducibility.
- Wear-Resistant Heavy-Plate Drum Shell: Built from high-tensile, abrasion-resistant carbon steel measuring 1000 mm in internal diameter and 1000 mm in length, resisting internal scouring, wall deformation, and dimensional warping over thousands of testing cycles.
- High-Torque Synchronous Drive System: Powered by a heavy-duty industrial electric motor and precision gear reduction train that reliably maintains a steady rotational velocity of 25 r/min, eliminating rotational slip and torque fluctuations under full test charges.
- Reinforced Hermetic Hatch Assembly: Equipped with quick-action clamping latches and high-resilience elastomer perimeter gaskets to ensure swift sample loading, hermetic sealing during operation, and clean discharge into receiving trays without fugitive sample loss.
- Multi-Screening Workflow Integration: Designed for rapid integration into standard testing workflows, operating smoothly alongside upstream pre-drum mechanical sizing screens, post-drum grading screens, and precision manual test sieves for rapid calculation of shatter and abrasion indices.
- Integrated Safety and Operational Interlocks: Features secondary mechanical drum locks, emergency stop systems, and perimeter safety limit switches to ensure total mechanical containment and worker safety during rapid drum indexing, loading, and cleaning.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Metallurgical Coking Plant Quality Control | Regular monitoring of production coke batches to establish shatter resistance (M40/M25) and abrasion resistance (M10) indices prior to shipment. | Prevents off-spec fuel delivery to blast furnaces, safeguarding thermal efficiency and operational consistency. |
| Blast Furnace Operations & Burden Management | Assessing the structural breakdown of incoming merchant coke under mechanical tumbling to optimize blast furnace charging matrices. | Preserves gas permeability and molten iron drainage in high-capacity blast furnaces by eliminating fine coke accumulation. |
| Commercial Inspection & Metallurgical Trade Assay | Third-party inspection and umpire assay of bulk coke consignments at shipping ports, rail terminals, and customs transit depots. | Delivers standardized, auditable mechanical degradation data fully aligned with international purchasing specifications. |
| Coal Blending & Coking Research | Pilot-scale testing of coked charges derived from novel coal blends, bio-coal additions, or coking additive formulations. | Accelerates formula development by quantifying the direct correlation between coal rank blends and resultant mechanical coke strength. |
| Refractory & Carbon Material Attrition Testing | Evaluation of non-coke carbon blocks, electrode pastes, and dense refractory aggregates subjected to repetitive tumbling impacts. | Provides actionable comparative data regarding fracture propagation and surface wear rates under mechanical stress. |
| Environmental Laboratory Modernization | Replacement of antiquated, unsealed drum testers with fully enclosed containment architecture in clean metallurgical research facilities. | Eliminates carcinogenic airborne dust emissions, reducing laboratory ventilation loads and occupational health risks. |
