Description

ATOMFAIR SBM-1L LABORATORY STIRRED BALL MILL ULTRASFINE GRINDING

RESEARCH GRADE EQUIPMENT

Product Overview

The ATOMFAIR SBM-1L 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 1 L with a maximum loading capacity of 0.35 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 1 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.

This stirred ball mill requires proper electrical grounding and mechanical guarding to prevent injury from rotating components. The grinding cylinder material and cooling jacket must be selected based on chemical compatibility and thermal load.

  • Electrical Safety: The mill must be connected to a grounded power supply matching the motor's rated power to prevent electrical hazards.
  • Mechanical Guarding: All rotating parts must be securely enclosed or guarded during operation to avoid entanglement.
  • Cooling Requirement: The grinding cylinder jacket requires a continuous coolant supply to maintain temperature within safe limits.
  • Material Compatibility: Grinding cylinder and stirrer materials must be chemically inert to the sample and grinding media to avoid contamination or degradation.

This procedure describes the safe startup and operation of the stirred ball mill for grinding fine powders. Follow each step sequentially to achieve the desired particle size distribution.

Required Equipment: Stirred ball mill unit, Grinding media (e.g., zirconia beads)

  1. Select Cylinder and Media
    Choose a grinding cylinder and stirrer material compatible with the sample and select appropriate grinding media size and material.
  2. Load Cylinder
    Load the grinding cylinder with the sample and grinding media, ensuring the total volume does not exceed the specified loading capacity.
  3. Secure Cylinder
    Close and seal the cylinder securely, then attach it to the mill and check that the jacket connections are properly fitted.
  4. Start Cooling
    Start the coolant flow through the jacket to establish temperature control before beginning the grinding process.
  5. Set Speed and Time
    Set the desired stirring speed and grinding time using the frequency converter and timer, then start the mill.
  6. Monitor Process
    Monitor the mill for abnormal vibration or noise and adjust cooling as needed to keep temperature within safe limits.
  7. Unload Product
    Stop the mill, raise the stirring rod using the automatic lift, tilt the cylinder, and carefully discharge the ground product.

How does the choice of grinding media size affect the achievable discharge particle size in the ATOMFAIR JM-1L stirred ball mill?

Larger grinding media produce coarser particles, while smaller media yield finer powder down to ≤1 μm as specified for the JM-1L model. The description states that a proper ratio of media sizes combined with speed adjustment optimizes grinding performance.

Can the ATOMFAIR lab stirred ball mill be used for wet grinding of contamination-sensitive materials such as pharmaceuticals or electronic ceramics?

Yes, the mill offers optional grinding cylinders and stirring components in non-metallic materials including corundum ceramic, polyurethane, zirconia, agate, and PTFE to prevent metal ion contamination. The jacket cooling system also allows precise temperature control, essential for heat-sensitive wet grinding applications.

What power and auxiliary infrastructure is required to operate the JM-100L production-scale ATOMFAIR stirred mill?

The JM-100L mill requires a 7.5 kW motor and a compatible frequency converter for speed regulation from 60–140 rpm. A cooling unit must be connected to the grinding cylinder jacket for temperature control, and the automatic lifting and tilting features require sufficient overhead space for safe operation.

This stirred ball mill provides excellent energy efficiency and precise temperature control via a jacketed cylinder, enabling reproducible fine grinding. However, optimal performance requires careful selection of grinding media and integration of auxiliary cooling and circulation systems.

Positive

  • High energy utilization and power density: The mill achieves outstanding energy-saving performance through high power density and energy utilization rate, reducing operational costs.
  • Precise grinding temperature control: The grinding cylinder is designed with a jacket, allowing precise control of the grinding temperature to maintain material stability during milling.

Trade-offs

  • Grinding media selection dependency: Grinding performance is highly dependent on the size, shape, and ratio of media; improper selection can lead to suboptimal particle size distribution.
  • Auxiliary cooling and circulation required: Operation depends on external circulation and cooling units for temperature management and material throughput, adding to system complexity.
