Automatic Microcomputer Plastometer Bituminous Coal Plastometric Indices Determination System

Product Overview

This automatic microcomputer coal plastometer is an advanced analytical testing system purpose-built for the rigorous evaluation of bituminous coal coking properties. Operating in full compliance with standardized plastometric testing methodologies, the equipment automates the characterization of coal plastic layer parameters, specifically determining the maximum plastic layer thickness (Y value), final contraction value (X value), and characteristic volumetric contraction curves. By combining high-precision thermal control with continuous kinematic recording, the instrument delivers essential predictive insights into coal thermoplasticity, swelling pressure, and metallurgical coke strength.

Engineered primarily for industrial coking plants, metallurgical foundries, coal preparation facilities, commercial testing laboratories, and energy research institutes, this testing platform streamlines routine coal quality verification and experimental coal blending. The system eliminates the operational complexities and manual recording errors traditionally associated with plastometric index determination, offering automated thermal ramps, continuous sensor data acquisition, and automated curve plotting. Whether deployed for single-sample assessments or high-throughput batch analyses, it ensures rapid, repeatable evaluations of diverse coking coals.

Constructed with industrial-grade mechanical assemblies, robust dual-channel electrical heating systems, and specialized quartz recording apparatus, the unit delivers consistent operational uptime under demanding laboratory conditions. A dual-interface architecture featuring synchronized microcomputer software and a dedicated hardware controller ensures complete supervisory visibility, fault isolation, and uninterrupted testing cycles. Laboratory managers and procurement teams can depend on this system for continuous compliance monitoring, precise coal classification, and maximized resource efficiency in carbon processing operations.
