Coal Gangue Slaking Inversion Testing Machine

Product Overview

This coal gangue slaking inversion testing machine is a specialized laboratory benchtop instrument engineered to evaluate the breakdown, disintegration, and fine slurry generation of coal gangue immersed in water under controlled dynamic tumbling. By mechanizing standard inversion cycles, the apparatus replicates the mechanical weathering, hydraulic degradation, and physical attrition that solid waste materials undergo during processing, coal washing, and hydraulic transport. The resulting suspension facilitates precise evaluation of residual mass yield and fine mud creation according to established analytical protocols.

Designed primarily for quality control and material characterization, the system serves coal preparation plants, metallurgical facilities, coking facilities, geological research institutions, and environmental monitoring laboratories. It delivers standardized slurry generation for downstream Andreasen pipette sedimentation and particle classification, enabling geologists and process engineers to predict tailing slime formation, optimize water clarification, and refine tailings management strategies.

Constructed with high-grade mechanical assemblies, a precision drive mechanism, and integrated thermal instrumentation, the equipment guarantees smooth, continuous operation and high experimental repeatability. Its robust horizontal shaft assembly, chemical-resistant sample bottle clamping system, and accurate speed stabilization ensure dependable service life even under daily, heavy-duty laboratory testing schedules.

Key Features

• Standard-Compliant Inversion Kinetics: The internal drive operates at a strictly controlled rotational speed of 40 r/min around a horizontal axis, reproducing standard mechanical shearing and tumbling dynamics in full alignment with coal and gangue slaking standards.
• Precision PT100 Thermal Monitoring: Equipped with a high-accuracy PT100 resistance temperature detector, the instrument measures test temperatures across a range of 0 to 90.9°C with ±0.1°C resolution and maintains temperature stability within ±0.2°C via a 1 kW auxiliary heating loop.
• Intuitive LED Digital Interface: An easy-to-read LED digital display delivers real-time feedback of operational cycles and test parameters, featuring both manual reset and automatic startup reset modes to eliminate operational oversight and streamline repeatable testing rounds.
• Energy-Efficient Drive System: The low-vibration 10 W drive motor provides balanced, continuous mechanical torque while consuming minimal power, mitigating structural wear on internal transmission components and ensuring long-term mechanical reliability.
• Secure Specimen Clamping Assembly: Engineered with heavy-duty retention chucks designed specifically for specialized ground-stoppered glass bottles, the clamping apparatus prevents slippage, liquid leakage, or structural stress on glassware during rapid inversion cycles.
• Integrated Particle Sizing Compatibility: The complete testing methodology standardizes sample preparation across 5.6 mm to 2.8 mm initial particle size brackets, pairing smoothly with 500 μm sieve separations and sub-10 μm Andreasen sedimentation procedures.
• Compact Laboratory Footprint: Measuring just 400 mm by 400 mm at the base and 860 mm in height, the vertical housing configuration maximizes laboratory benchtop utility while retaining structural mass for vibration dampening.
• Corrosion-Resistant Structural Enclosure: Finished with an industrial-grade, chemical-resistant protective coating, the housing withstands wet laboratory conditions, corrosive mine water residues, and abrasive fine gangue particles.
