Description

SPBM-2A LATERAL PLANETARY BALL MILL (LABORATORY TYPE)

LABORATORY GRADE EQUIPMENT

Product Introduction
SPBM-2A is a compact laboratory-type lateral planetary ball mill designed for mixing, ultra-fine grinding, small sample preparation, new product development, and small-batch production of high-tech materials. The SPBM series features a compact design with complete functionality, high grinding efficiency, and low operating noise—making it the core equipment for preparing experimental powder samples in universities, research institutes, and enterprise R&D laboratories. With a single run capable of simultaneously preparing four samples and compatibility with vacuum grinding jars for closed-environment material grinding, SPBM-2A offers versatility for diverse research applications. Key specifications include a total volume of 2 L, four standard 500 mL grinding jars, a net weight of 85 kg, overall dimensions of 760×470×600 mm, 0.75 kW motor power, adjustable planetary disk speed of 0–335 rpm, jar rotation speed of 0–810 rpm at a 1:2 speed ratio, and a 220V 50Hz single-phase power supply with variable frequency stepless speed regulation, timing, and forward-reverse cycle control.

PACKAGING: This listing is priced for the SPBM-2A main unit only. The standard configuration includes 1 pc grinding host machine with variable frequency drive, timing control, and forward-reverse cycle functions. Grinding jars and grinding balls are ordered separately. Installation guidance and operational training support are provided upon request.
IMPORTANT NOTICE: The listed price is for the main unit; grinding jars and balls must be ordered separately. Select jar and ball materials compatible with your target material to avoid cross-contamination. The maximum jar loading capacity is two-thirds of jar volume. For detailed installation, operation, and maintenance instructions, consult the user manual prior to first use.

The mill requires a stable, level surface and 220V/50Hz single-phase power with proper grounding. The safety lock switch must be engaged before operation; only use grinding jars and balls rated for the SPBM-2A and ensure vacuum jar seals are intact for vacuum grinding.

  • Electrical Safety: Connect the mill to a grounded 220V/50Hz single-phase outlet and verify overload protection is functional before each use.
  • Locking Mechanism: Engage the safety lock switch prior to starting any grinding cycle and never operate the mill with the lock disengaged.
  • Jar and Ball Compatibility: Select grinding jars and balls from approved materials (stainless steel, ceramic, polyurethane, agate, YSZ, etc.) to avoid mechanical mismatch or contamination.
  • Vacuum Grinding Sealing: For vacuum atmosphere grinding, confirm the optional vacuum jar lid seal is intact and the vacuum port is properly closed before initiating the cycle.
  • Noise Exposure Limits: Operate the mill at or below 60±5 dB; use hearing protection if the mill is operated in an enclosed or reverberant space.

This procedure outlines the critical steps for safe and effective operation of the SPBM-2A. Always consult the user manual for detailed installation and maintenance instructions.

Required Equipment: SPBM-2A Main Unit

  1. Install and Level the Mill
    Place the SPBM-2A on a stable, vibration-dampened surface and verify it is level using the adjustable feet if available.
  2. Connect Power and Verify Safety
    Plug the mill into a properly grounded 220V/50Hz single-phase outlet and confirm the overload protection indicator is illuminated.
  3. Load Grinding Jars and Balls
    Fill each of the four jar stations with the appropriate grinding balls and sample material, then securely fasten the jar lids according to the manufacturer's instructions.
  4. Engage the Safety Lock
    Close the mill door and engage the safety lock switch; ensure the lock clicks into place before proceeding.
  5. Set Grinding Parameters and Start
    Use the programmable control panel to set total running time (1–9999 min) and bidirectional rotation interval (1–999 min), then press start.

How does the 0.75 kW motor on the SPBM-2A affect grinding performance trade-offs for a 2 L total volume compared to higher-powered models in the series?

The 0.75 kW single-phase motor provides sufficient energy density for the 2 L configuration, enabling a revolution speed of 0–335 rpm and a jar speed of 0–810 rpm at a fixed 1:2 ratio. This allows ultrafine grinding down to 0.1 μm, as specified, without the need for three-phase power. For higher throughput or harder materials, larger models like the SPBM-16A use a 3 kW three-phase motor but require a 380 V supply, representing a trade-off between power infrastructure and lab-scale requirements.

Can the SPBM-2A be configured for vacuum or inert gas grinding of air-sensitive materials, and what are the jar compatibility requirements?

Yes, the SPBM-2A supports vacuum and inert atmosphere grinding when fitted with optional 50–250 mL vacuum grinding jars, which must be ordered separately. Standard jars (Al₂O₃, PU, PTFE, ceramic, stainless steel, nylon) are not vacuum-rated and cannot be used for this application. The system includes a safety interlock that must be engaged for safe vacuum operation.

What electrical and spatial infrastructure is needed to install the SPBM-2A in a shared laboratory environment?

The SPBM-2A requires a 220 V/50 Hz single-phase supply rated at 0.75 kW, with frequency conversion speed control drawing standard laboratory outlet power. Its dimensions are 760 × 470 × 600 mm and it weighs 85 kg, so a sturdy benchtop or floor mount is necessary. Operating noise is 60 ± 5 dB, compatible with most lab settings, and the safety lock switch must be engaged prior to operation.

The SPBM-2A vertical semi-circular planetary ball mill delivers 0.1 μm ultrafine grinding with four-station parallel processing and vacuum atmosphere compatibility, ideal for air-sensitive material research, but requires separate purchase of grinding jars and media, and careful material compatibility selection to avoid cross-contamination.

Positive

  • Ultrafine grinding down to 0.1 μm: Planetary motion with revolution-to-rotation ratio 1:2 achieves high energy density and three-dimensional movement, enabling particle size reduction to 0.1 μm for advanced material research.
  • Four-station parallel sample processing: Simultaneous grinding of up to four samples in a single experiment increases throughput for comparative studies and small-batch pilot production.

Trade-offs

  • Grinding jars and media ordered separately: The main unit does not include jars or balls; buyers must select compatible materials (e.g., Al₂O₃, YSZ, agate) to avoid cross-contamination, adding procurement steps and potential compatibility issues.
  • Requires material compatibility verification: To prevent contamination, jar and ball materials must be matched to the target sample, necessitating prior knowledge of material reactivity and wear properties.
