Product Overview
This caking index determination apparatus is a specialized laboratory testing instrument engineered to evaluate the bonding capacity, caking index, and Roga index of bituminous coal. Designed and manufactured in strict compliance with standard industrial methodologies such as GB/T 5447-2014, the equipment quantifies the adhesive plastic mass and mechanical cohesion generated during thermal coal decomposition. By subjecting carbonized blends of pulverized coal and standard anthracite substrate to controlled rotational abrasion, the system delivers reproducible, empirical insights into coal agglomeration, plastic layer behavior, and resultant coke strength.
Built to support high-throughput industrial and scientific laboratories, this instrument serves coal preparation facilities, coking plants, metallurgical smelters, and combustion research institutions. It performs an essential role in raw material intake inspection, coal blending formulation, and coking pressure prediction. By accurately differentiating the adhesive capabilities of varying bituminous grades, the unit helps plant metallurgists maintain blast furnace productivity, reduce raw material costs, and prevent premature refractory wear caused by sub-optimal coal charges.
Engineered with an emphasis on mechanical stability and analytical precision, this system delivers dependable performance in aggressive laboratory environments characterized by fine coal dust and continuous operation. A high-efficiency drive assembly paired with an intelligent pulse-sensing counter guarantees stable drum rotational dynamics and eliminates mechanical slippage. The result is total consistency across test cycles, providing laboratory managers and quality directors with absolute confidence in their fuel classification and procurement data.
Detail & Parts
Key Features
- Precise Rotational Velocity Regulation: The internal drive mechanism maintains drum rotation at exactly 50 ± 0.5 revolutions per minute, preventing centrifugal variances from skewing the mechanical wear patterns of carbonized coke residue.
- Microprocessor-Driven Pulse Detection: Integrated digital circuitry provides automated pulse identification and real-time count registration, eliminating human monitoring errors and mechanical backlash common in manual dial counters.
- Flexible Revolution Preset Range: Operators can freely configure rotation parameters from 1 to 999 revolutions, enabling standard test cycles of 250 revolutions as well as specialized experimental wear protocols for non-standard fuels.
- Dual-Mode Reset Architecture: The instrument features both automated cycle-completion reset and manual operator override capabilities, streamlining consecutive sample workflows and reducing setup times between tests.
- High-Contrast Liquid Crystal Display: A rugged LCD panel presents operational status, preset revolution targets, and real-time drum counts with extreme clarity, ensuring rapid parameter verification even in dimly lit industrial control areas.
- Robust 90W Continuous-Duty Motor: A powerful, thermally protected 90-watt electric drive delivers uniform starting torque and maintains unvarying angular velocity regardless of internal drum friction or sample mass fluctuations.
- Rigid Abrasion Drum Housing: Machined with heavy-gauge industrial materials, the rotating drum assembly resists micro-deformation and abrasive erosion during thousands of test runs with abrasive coal-anthracite mixtures.
- Comprehensive Standard Compliance: Built specifically around the operational mechanics defined by GB/T 5447-2014, the equipment guarantees analytical alignment with global coal classification, trade valuation, and metallurgical indices.
