HTJC-9 Automatic Adhesive Layer Index Tester (Ventilated Type) is designed to determine the plastometer indices of bituminous coal, characterize coke properties, and evaluate the quality of coking coal, industrial coal, and commercial coal. As essential equipment for laboratories in coal washing plants and coking plants, it measures three key plastometer indices: maximum thickness of plastic layer (Y), contraction (X), and volume curve. Compliant with GB/T 479 “Method for Determination of Plastometer Indices of Bituminous Coal,” it delivers high precision, user-friendly operation, and stable performance, making it ideal for coal quality testing in coal, metallurgy, and coking industries.

Features:

1. Computer-Controlled Operation:

Automatically regulates temperature and plots volume curves per GB/T 479-2000, minimizing human intervention and errors.

• Integrated Ventilation System:

Equipped with a variable-frequency DC motor for efficient fume extraction, eliminating the need for external fume hoods.

• Automatic Weight Loading:

No manual weight attachment required; lever-free design ensures precise and effortless operation.

• Self-Aligning Probe：

Automatically adjusts the parallelism between the probe and paper tube for enhanced reliability.

• Smart Robotic Measurement:

Simulates manual probing to measure upper/lower plastic layer thickness without disturbing the sample.

• Data Integrity & Recovery:

Real-time data saving, historical data retrieval, and power failure recovery to resume interrupted tests.

• Safety & Alerts:

Automatic fault detection (e.g., temperature control failure) with alarms and power cutoff.

• Dual-Furnace Option:

Supports single- or dual-furnace tests; all live electrical parts are insulated for safety.
