Coal Gangue Slaking Inversion Tumbling Test Apparatus

Product Overview

This specialized tumbling test apparatus is engineered to evaluate the degree of slaking, mudding, and mechanical degradation of coal and associated gangue minerals under controlled aquatic agitation. Built in strict accordance with standard geological and mineral testing requirements, the system mechanizes the inversion cycle of immersion vessels to deliver reproducible fluid-rock interaction dynamics. By systematically agitating prepared mineral fractions and enabling subsequent precise sedimentation and sieving analysis, the unit provides critical baseline data on mineral disintegration tendencies, ultrafine particle generation, and hydraulic stability.

Primarily utilized across coal preparation facilities, metallurgical washing plants, coking operations, and mining research institutes, this testing instrument addresses the challenges of slime water management and tailings handling. Evaluating gangue slaking behavior prior to large-scale processing is vital for predicting filter press efficiency, closed-loop water circuit clarification, and aggregate degradation in civil backfill applications. The instrument standardizes sample agitation to eliminate manual variability, providing dependable quantification of sub-10 µm slime yield and coarse degradation rates.

Constructed for continuous operation within rigorous quality-control environments, the equipment integrates a stabilized gear-driven rotation assembly, high-precision thermal monitoring with PT100 sensor technology, and an intuitive digital control interface. Its vibration-damped vertical layout ensures steady kinetic transfer while maintaining whisper-quiet, energy-efficient operation. Industrial laboratory personnel can rely on its consistent rotational velocity and thermal accuracy to produce repeatable, audit-ready mineral characterization data run after run.

Key Features

• Regulated Rotational Velocity: The central drive assembly maintains a stabilized shaft speed of exactly 40 r/min, ensuring constant kinetic energy distribution across all tumbling cycles in accordance with regulatory test criteria.
• High-Precision Thermal Monitoring: Outfitted with an industrial-grade PT100 thermocouple, the instrument delivers continuous thermal tracking from 0 to 90.9 °C with a resolution and measuring accuracy of ±0.1 °C for exacting analytical repeatability.
• Integrated Temperature Regulation: A built-in closed-loop thermal management system delivers active control accuracy within ±0.2 °C and supports up to 1 kW auxiliary heating management to replicate diverse reservoir and washing process temperatures.
• Digital LED Process Interface: A high-contrast digital LED display presents real-time operational parameters, featuring clear visual indicators along with versatile manual reset and power-on automatic reset routines for seamless batch workflows.
• Ultra-Low Energy Kinetic Drive: The primary agitation motor consumes less than 10 W of electrical power during active rotation, maximizing thermal stability by preventing parasitic heat transfer into the test suspension.
• Rugged Vertical Architecture: Engineered with a rigid, corrosion-resistant chassis occupying a compact 400 mm × 400 mm laboratory footprint, this self-standing frame prevents torsional distortion and rotational wobble.
• Standard-Compliant Inversion Geometry: The internal tumbling fixture secures cylindrical reaction bottles to enforce axial 360-degree liquid-solid contact, replicating authentic hydrodynamic shearing and attrition kinetics without inducing unnatural impact crushing.
• Electromagnetic and Environmental Shielding: Internal circuitry and measurement components are shielded against external electromagnetic interference, maintaining clean signal fidelity in busy industrial laboratory settings.
