Product Overview
This industrial-grade drum testing machine provides precise, standardized mechanical degradation analysis for iron ore sinter and fired pellets. By simulating the violent abrasive and compressive impacts experienced throughout metallurgical handling, stockpile transfer, and blast furnace descending column operations, the equipment accurately quantifies the tumble index and abrasion index of burden materials.
Engineered specifically for steelworks, sintering plants, pelletizing facilities, and contract testing laboratories, this testing system enables quality assurance teams to verify batch structural integrity prior to furnace charging. Consistent monitoring of these indices directly impacts furnace permeability, decreases flue dust generation, and optimizes coke consumption rates across industrial reduction processes.
Manufactured in strict conformance with standardized metallurgical testing protocols, the heavy-gauge test drum, reinforced structural chassis, and integrated screening decks ensure mechanical reliability under punishing daily testing regimes. The unit is available in standard configurations or environmental variants equipped with dust control hoods to safeguard laboratory air quality during high-energy aggregate tumbling.
Detail & Parts
Key Features
- Strict Metallurgical Standard Compliance: Fully aligned with YB/T 5166 specifications, ensuring that drum rotation rates, internal barrel geometry, and lifting mechanisms generate certified, repeatable tumbler and abrasion index data for commercial quality control.
- Reinforced Drum Assembly: Fabricated from high-tensile, wear-resistant steel plates measuring 1000 mm in diameter and 500 mm in length, providing extreme resistance to internal abrasion and deformation under continuous impact testing.
- Accurate STS-3 Digital Automation: Integrates an STS-3 digital electronic revolution counter that automatically arrests the drive system precisely upon completing the mandatory 200 revolutions, preventing operator over-run errors.
- Heavy-Duty Torque Reduction Drive: Powered by an efficient 1.5 kW electric motor coupled to an industrial-grade speed reduction gearbox, maintaining a constant 25 rpm barrel rotational velocity under uneven dynamic loads.
- Dual-Stage Pre-Drum Vibrating Screen: Includes a matched 1600 × 500 mm double-deck vibratory screen driven by a 2.2 kW motor, operating at a 10° to 11.5° inclination with a 6 to 8 mm stroke to accurately separate sample feed fractions (40 mm, 25 mm, 16 mm, and 10 mm).
- High-Efficiency Post-Drum Oscillating Sieve: Features a dedicated 800 × 500 mm screening station with a 45° oscillation mechanism and a 1.1 kW drive, completing standardized fines fractioning (6.3 mm or 5.0 mm apertures) in an automated 1.5-minute cycle.
- Flexible Environmental Configurations: Offered in both standard robust open-chassis models and specialized environmental models fitted with comprehensive dust extraction hoods to maintain clean, particulate-controlled lab air.
- Ergonomic Rapid-Discharge Mechanism: Engineered with quick-clamping inspection covers and integrated collection trays that streamline sample loading and post-test recovery, minimizing operator strain and downtime.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Blast Furnace Quality Assurance | Evaluates the mechanical strength of sinter and pellet batches prior to furnace burden charging. | Prevents blast furnace shaft permeability loss by detecting weak agglomerates before they generate excessive burden fines. |
| Sintering Plant Process Tuning | Continuously monitors the tumble index and abrasion index to evaluate fuel mix ratios, bed depth, and ignition settings. | Delivers immediate empirical feedback to optimize sintering furnace thermal profiles and raw mixture basicity. |
| Pelletizing Plant Quality Verification | Assesses cold crushing resilience and resistance to degradation during transport for green and fired iron ore pellets. | Ensures pellet binders and induration firing temperatures achieve the mechanical hardness required for bulk distribution. |
| Commercial Metallurgical Inspection | Serves third-party analytical and inspection laboratories conducting contractual acceptance testing for ore shipments. | Provides audit-compliant test methodology that matches binding commercial specifications and commodity trading contracts. |
| Pyrometallurgical Research | Allows university and institutional research facilities to measure the mechanical properties of alternative fluxed ores and low-carbon agglomerates. | Yields high-precision comparative data on experimental binders, hydrogen-reduced sinters, and biochar-infused iron burdens. |
| Bulk Port Material Handling | Assesses aggregate degradation risks across transfer chutes, stacker-reclaimers, and ship loading conveyors. | Establishes realistic handling limits and degradation allowances for maritime and rail ore transit networks. |
