Description

ATOMFAIR SBM-2L LABORATORY STIRRED BALL MILL ULTRASFINE GRINDING

RESEARCH GRADE EQUIPMENT

Product Overview

The ATOMFAIR SBM-2L is a Laboratory Stirred Ball Mill classified as a Lab TYPE unit, driven by a 0.37 kW motor with frequency speed control offering a continuously variable speed range of 50–1400 rpm. The mill features a total volume of 2 L with a maximum loading capacity of 0.7 L, accepting feed material up to ≤5 mm and delivering ultrafine grinding output ≤1 μm. The stirred mill consists of a stationary grinding chamber filled with small-diameter media, a stirring device, and auxiliary systems including circulation, jacketed cooling for precise temperature control, timing, and speed regulation. The grinding efficiency is significantly higher than conventional ball mills due to the high power density design. The stirring shaft features automatic lifting and the grinding chamber supports free tilting for convenient loading, unloading, and cleaning. Grinding jars and grinding balls are ordered separately. The SBM series spans from 1 L laboratory models to 600 L production units, covering research, pilot, and full-scale production applications across ceramics, chemicals, electronics, magnetic materials, coatings, pharmaceuticals, and new materials processing.

Key Features & Advantages

  • High Energy Utilization with Ultrafine ≤1 μm Output: The stirred mill design achieves significantly higher power density than conventional ball mills, delivering superior energy efficiency and consistent ultrafine grinding to particle sizes ≤1 μm from maximum feed of 5 mm.
  • Jacketed Grinding Chamber for Precise Temperature Control: The double-walled cooling jacket enables effective heat dissipation during extended grinding operations, preventing thermal degradation of temperature-sensitive materials and ensuring consistent product quality.
  • Automatic Lifting Stirring Shaft with Free Tilting Chamber: The stirring shaft features automatic lifting capability and the grinding chamber supports free tilting, facilitating convenient loading, unloading, and cleaning between experiments.
  • Multiple Jar and Ball Material Options for Contamination Control: Nine grinding jar materials and seven ball materials enable contamination-free processing of diverse materials from ceramics to pharmaceuticals.

APPLICATION SCOPE: Laboratory ultrafine grinding and powder processing for material science research. Suitable for zirconium silicate, zirconia, alumina, ceramics, chemicals, electronic materials, magnetic materials, papermaking, coatings, non-metallic minerals, new materials, paints, graphite, calcium carbonate, and pharmaceutical fine powder production. Compatible with both continuous and batch processing modes with frequency speed control for process parameter optimization.
PACKAGING: The standard configuration includes 1 pc grinding host machine. Grinding jars (1 pc of 2 L, available materials: WC-Co, Al₂O₃, Agate, YSZ, SS, PU, Ceramic, Nylon) and grinding balls (WC-Co, Al₂O₃, Agate, YSZ, SS, IC-PU, HCCI) are ordered separately. The SBM series is available from 1 L laboratory models through 600 L production units. Installation guidance and operational training support are provided upon request.
IMPORTANT NOTICE: Grinding jars and balls must be ordered separately. Select jar and ball materials compatible with your target material to avoid cross-contamination. The jacketed cooling system should be connected to an appropriate cooling water supply for temperature-controlled grinding. Product particle size can be adjusted by controlling material residence time within the grinding chamber. For detailed installation, operation, and maintenance instructions, consult the user manual prior to first use.

Operate the mill within the rated electrical and mechanical limits to prevent equipment damage or personal injury. Ensure proper material compatibility and temperature control to avoid hazardous reactions or component failure.

  • Electrical Safety: Connect the mill to a properly grounded power source matching the motor rating to prevent electrical shock or fire.
  • Mechanical Hazard: Keep hands and loose clothing away from rotating stirring rod and tilting cylinder during operation.
  • Material Compatibility: Select grinding cylinder and stirring rod materials that are chemically inert to the processed material to avoid contamination or corrosion.
  • Temperature Management: Use the jacket cooling system to maintain the grinding temperature within safe limits for both equipment and material.
  • Loading Capacity: Do not exceed the specified loading capacity of 0.7 L to prevent overloading and mechanical stress.

This procedure outlines the safe initialization and operation of the laboratory stirred ball mill. Follow each step sequentially to ensure proper handling and avoid mechanical or electrical hazards.

Required Equipment: Grinding cylinder, Stirring rod assembly, Grinding media, Cooling jacket

  1. Inspect Components
    Inspect the grinding cylinder and stirring rod for cracks or wear before assembly.
  2. Load Grinding Media
    Fill the cylinder with the appropriate grinding media to approximately one-third of its volume.
  3. Add Material
    Load the material into the cylinder without exceeding the maximum loading capacity of 0.7 L.
  4. Set Speed
    Set the desired rotational speed between 50 and 1400 rpm using the frequency converter.
  5. Start Milling
    Start the mill and monitor the temperature via the jacket, adjusting coolant flow as needed.
  6. Stop and Unload
    Stop the mill after the desired grinding time and carefully tilt the cylinder to discharge the product.

How does the JM-2L's loading capacity of 0.7 L affect its grinding efficiency and the fineness achievable for powder processing?

The JM-2L has a recommended loading capacity of 0.7 L relative to its total 2 L volume, which ensures optimal media-to-material contact for efficient grinding. Product fineness is controlled by adjusting the residence time of the material in the cylinder and the rotational speed over the 50–1400 rpm range. Higher speeds and longer residence times produce finer particles, though the exact discharge particle size depends on the grinding media selection and the material's mechanical properties.

Which material options are available for the grinding cylinder and stirrer of the JM-2L to prevent contamination when milling reactive or abrasive compounds?

The JM-2L supports optional grinding cylinders and stirring components made from stainless steel, corundum ceramic, polyurethane, and zirconia, among others. Selecting a material that is chemically inert and harder than the sample minimizes wear and prevents contamination. The mill can be configured with different material sets to match the specific needs of ceramics, battery materials, or pharmaceutical compounds.

What electrical and cooling utilities are required to operate the JM-2L's automatic stirrer lift and jacket temperature control?

The JM-2L requires a standard single-phase electrical supply for its 0.37 kW motor and a cooling fluid supply to the jacket for temperature control during extended milling runs. The automatic stirring rod lift and free-tilting cylinder operate without additional pneumatic or hydraulic infrastructure, only requiring adequate bench clearance. No special ventilation or high-pressure utilities are necessary, making the unit straightforward to install in standard laboratory settings.

The JM-2L Lab Stirred Ball Mill delivers efficient fine grinding for laboratory-scale research with a 0.37 kW motor and 2 L grinding volume, capable of discharging particles as fine as ≤1 μm. Its jacketed cylinder enables temperature control, but optimal performance hinges on careful selection of grinding media and is inherently limited to small batch processing.

Positive

  • High energy utilization and power density: Achieves outstanding energy-saving performance through high energy utilization rate and high power density, reducing operational costs during extended grinding runs.
  • Adjustable product particle size: Fineness is easily controlled by varying the residence time of materials in the grinding cylinder, allowing precise tailoring of output particle size for different applications.

Trade-offs

  • Limited to small batch processing: With a 2 L total volume and only 0.7 L loading capacity, the mill is restricted to small-batch work, making it unsuitable for larger sample volumes or production-scale trials.
  • Requires media selection and speed adjustment expertise: Optimal grinding performance depends on choosing the correct grinding media size, shape, ratio and speed, demanding operator experience to achieve desired fineness and efficiency.
