Bituminous Coal Caking Index Tester and Automatic Static Press System

Product Overview

This dual-function analytical system unites a bituminous coal caking index drum tumbler and an automatic static pressure compactor into a single space-saving benchtop console. Consolidating specimen briquetting and mechanical abrasion into one station eliminates redundant equipment and streamlines daily laboratory sample workflows.

Engineered for metallurgical coking facilities, coal preparation plants, and commercial testing laboratories, this unit determines the caking capacity (G-index) and Roga index of bituminous coals. These critical metrics enable fuel engineers to optimize coal blend formulations, evaluate coking compatibility, and ensure finished coke strength for blast furnace operations.

Built for demanding multi-shift industrial service, the equipment features a balanced drive assembly that ensures smooth, low-vibration rotation and low acoustic noise. Precision digital cycle controls guarantee dependable test repeatability and full compliance with standard coal classification protocols.

Key Features

• Dual-Function Integrated Architecture: By incorporating an automated static press mechanism and a motorized tumbling drum on a shared structural chassis, this equipment eliminates the capital expense and footprint of separate preparation apparatuses. Laboratory technicians can compress anthracite-diluted coal briquettes and initiate tumbling wear cycles within a single organized station, minimizing transit time and sample disturbance.
• Standard-Compliant Drum Velocity: The precision drive assembly sustains a constant rotational speed of 50 ± 2 r/min throughout the full testing duration, strictly matching the kinetic energy parameters required by standardized caking index protocols. Controlled rotational speed guarantees reproducible particle collisions and accurate quantification of coal agglutination strength.
• Automated Preset Revolution Control: Equipped with an internal cycle controller, the system automates the standard 250-revolution test run without requiring constant manual oversight. This automated cycle termination prevents over-rotation or under-rotation errors, ensuring consistent experimental baselines across consecutive shifts and differing lab technicians.
• High-Luminance Digital Display: A bright digital LED tube display provides continuous, at-a-glance visibility of accumulated drum rotations. The high-contrast readout ensures that laboratory personnel can track tumbling progress from anywhere in the testing suite, even in high-glare or dimly lit industrial environments.
• Acoustic Completion Warning: An integrated audible buzzer signals immediately when the drive assembly reaches the target 250-revolution limit. This automated acoustic indicator notifies busy technicians to proceed with sieving and weighing, preventing samples from settling or absorbing atmospheric moisture inside the drum.
• Vibration-Damped Mechanical Powertrain: Machined with dynamic balancing and rigid structural mounts, the rotating assembly generates exceptionally low mechanical vibration and subdued operating noise. This balanced motion prevents uneven drum oscillations, protects internal bearings from fatigue, and creates a quieter working environment in high-volume testing labs.
• Precision Automated Static Compaction: The integrated static pressure compactor delivers uniform, perpendicular mechanical loading to compact the mixture of coal and standard anthracite prior to carbonization. Automated compression eliminates operator-to-operator tamping discrepancies, ensuring identical briquette density and uniform thermal conductivity during downstream crucible heating.
• Low-Power High-Torque Electrical Drive: Engineered to draw merely 42 W under normal load conditions, the unit combines extreme energy efficiency with high startup torque. The robust motor easily handles the shifting internal coal mass without speed droop, operating reliably from common 220V 50Hz single-phase electrical outlets.
