This high-performance sample preparation system is an advanced dual-station laboratory vibratory disc mill engineered for rapid size reduction of medium-hard, hard, brittle, and fibrous materials. Driven by a high-torque 1.5 kW motor generating 1500 r/min circular motion, the unit applies multi-directional kinetic energy, combining extreme multidirectional pressure and friction to reduce feed sizes under 15 mm down to ultra-fine analytical powders under 20 microns within minutes. Featuring two independent grinding stations, this system effectively doubles sample processing efficiency for demanding analytical laboratories.

Built to fulfill rigorous sample preparation requirements in X-ray fluorescence (XRF), atomic absorption spectroscopy (AAS), inductively coupled plasma (ICP) analysis, and quality control routines, the equipment accommodates batch processing volumes ranging from 15 mL up to 1000 mL. The unit features standard support for vacuum and inert gas protective atmospheres, preventing oxidation, atmospheric moisture absorption, or thermal breakdown of sensitive specimens during high-intensity milling. Its flexible chamber configuration accommodates grinding set sizes of 100 mL, 250 mL, and 500 mL across diverse specialized material formulations.

Constructed with an IP65-rated heavy-duty enclosure and industrial-grade vibration isolation components, this system ensures total mechanical stability and operational safety during continuous high-load pulverization. Combining quick-clamping technology, intelligent power-off memory functions, and optional real-time sensor integration, the unit delivers consistent, reproducible, contamination-free analytical samples across metallurgy, geology, construction materials, ceramics, and environmental testing sectors.

Key Features

  • Dual-Station High-Throughput Processing: Equipped with dual mounting stations operating in synchronized circular motion, allowing simultaneous grinding of two separate analytical batches to double laboratory throughput while maintaining uniform energy input.
  • High-Impact Circular Motion Drive: Powered by a robust 1.5 kW electric drive operating at 1500 r/min, generating intense impact pressure and surface friction forces capable of rapidly pulverizing stubborn materials down to sub-20 micron analytical fineness.
  • Comprehensive Atmosphere Protection: Fully compatible with vacuum evacuation and inert gas purge protocol (argon/nitrogen), protecting sensitive samples from degradation, oxidation, and unwanted ambient moisture contamination during dry or wet grinding operations.
  • Ergonomic Quick-Clamping System: Features an intuitive quick-action clamping mechanism that securely locks grinding sets into position without requiring specialized hand tools, eliminating manual fatigue and minimizing sample changeover time.
  • Versatile Grinding Media Selection: Supports interchangeable grinding sets in volumes of 100 mL, 250 mL, and 500 mL, available in tungsten carbide, zirconia, agate, and stainless steel to eliminate cross-contamination and match specific hardness requirements.
  • Intelligent Process Automation: Built-in digital timer customizable up to 9999 minutes supports both continuous and intermittent milling regimes, complete with an integrated power-off memory function to ensure process continuity after power interruptions.
  • Illuminated Chamber with Observation Window: Integrated high-efficiency LED internal illumination and a reinforced front observation window enable clear visual monitoring of milling operations without opening the protective housing.
  • Advanced Sensor and Cryogenic Upgrade Capability: Modular architecture accommodates optional cryogenic liquid nitrogen cooling attachments, interactive touchscreen controls, and live sensor monitoring for internal grinding set pressure and temperature.
  • Industrial Grade IP65 Enclosure: Enclosed in a heavy-duty frame rated to IP65 ingress protection standards, safeguarding internal electronics and heavy mechanical drives against dust infiltration and liquid splash hazard during demanding work shifts.

Applications

Application Description Key Benefit
XRF Sample Preparation Rapidly pulverizes geological ores, cement clinker, minerals, and slag samples into homogenous powders sub-20 µm. Ensures optimal pelletization density and analytical accuracy for high-throughput XRF spectrographic analysis.
Metallurgy & Alloy Testing Processes brittle ferroalloys, metal oxides, ores, and furnace slags under high-energy mechanical impact. Achieves fine particle size reduction without altering chemical stoichiometry or introducing unwanted elemental trace contaminants.
Mining & Geological Exploration Grinds hard rocks, quartz, soil, silicates, and core samples in large batch volumes up to 1000 mL. High-throughput dual-station design processes heavy sample volumes rapidly while enduring abrasive wear.
Advanced Ceramics & Glass Pulverizes raw glass batches, technical ceramics, raw porcelain, and refractory compounds. Inert grinding set choices like tungsten carbide and zirconia eliminate cross-metallic contamination in ultra-pure formulas.
Environmental & Soil Analysis Reduces dried sediment, sewage sludge, contaminated soils, and fibrous botanical specimens under wet or dry conditions. Provides flexible, reproducible size reduction suitable for heavy metal extractions and trace element analysis.
Cryogenic & Inert Gas Milling Grinds moisture-sensitive, heat-sensitive, or easily oxidizable chemical samples under LN2 cooling or argon gas purge. Prevents sample thermal oxidation, thermal degradation, and unwanted moisture adsorption during fine size reduction.
Construction Materials & Cement Pulverizes concrete, gypsum, clinker, limestone, and building materials to exact fineness standards. Delivers consistent, reproducible grain distribution profiles essential for strict quality assurance and standards compliance.
