Fully Automatic Caking Index Tester Bituminous Coal Coking Property Analyzer

Product Overview

This system is an automated analytical instrument engineered to evaluate the caking capacity, thermal plasticity, and agglutinating properties of bituminous coal. By standardizing and automating sample blending, static compaction, and mechanical drum abrasion testing, the equipment calculates both the Caking Index (G value) and Roga Index with consistent accuracy. It eliminates manual inconsistencies in sample preparation, providing metallurgical facilities with dependable baseline data to optimize coal blending, predict coke cake formation, and ensure uniform blast furnace coke quality.

Designed for demanding industrial environments, this unit serves coal preparation plants, coking operations, metallurgical smelting facilities, and fuel research institutions. Evaluating the caking power of bituminous coal is essential for managing blend proportions in coke ovens, conserving premium coking coals, and preventing oven wall damage. By standardizing critical mechanical interactions, the instrument allows laboratory technicians to conduct routine quality control tests and complex coal rank evaluations with high productivity and minimal labor intervention.

Manufactured with precision drive components and a responsive touchscreen interface, the system delivers steady operation under high-throughput laboratory conditions. Real-time dynamic simulation graphics, automated status indicators, and precise rotational velocity control allow operators to monitor test sequences directly. Built in strict alignment with national and international standard test methods, the equipment gives procurement teams and laboratory managers full confidence in its analytical accuracy, hardware durability, and compliance with metallurgical testing protocols.

Key Features

• Integrated Three-in-One Automated Workflow: Integrates automatic tilted mixing, calibrated static pressing, and standardized drum tumbling into a unified operational sequence, completing the entire Caking Index protocol without manual sample transferring or intermediate handling.
• Dual-Motion Synchronized Stirring Kinematics: Employs a 45-degree crucible tilt rotating at 15 r/min combined with a high-speed stirring wire rotating in reverse at 150 r/min for 1 minute 45 seconds, followed by 15 seconds of vertical mixing to ensure homogenous dispersion of coal and anthracite particles.
• Regulated Static Pressure Briquetting: Automatically applies a calibrated 6 kg static compression force to the mixed sample for exactly 30 seconds, forming a standardized coal briquette of uniform density and dimensions prior to carbonization.
• Precision Abrasion Drum Mechanism: Rotates the standard metallurgical test drum at a controlled speed of 50 ± 2 r/min through an exact 250-revolution cycle, accurately quantifying post-coking abrasion resistance and mechanical friability.
• High-Resolution Dynamic Touchscreen Interface: Displays real-time countdown timers, operational phase notifications, exact rotational speeds, and dynamic workflow simulations on an industrial-grade color touchscreen for complete process transparency.
• Simultaneous Dual-Sample Testing: Engineered with a dual-station configuration that accommodates two samples concurrently, doubling laboratory throughput and enabling direct parallel verification of coal samples under identical test conditions.
• Compact Low-Power Electromechanical Drive: Houses all high-torque geared mechanisms within a space-saving 400 × 455 × 340 mm benchtop footprint that consumes only 54 W, optimizing valuable laboratory workspace while lowering operational energy consumption.
• Standardized Quality Metric Output: Automatically calculates the coal caking index G value based on the mass of coke fragments retained above designated sizing thresholds after drum abrasion, streamlining laboratory reporting and quality grading.
