Description

SPBM-8A LATERAL PLANETARY BALL MILL (LABORATORY TYPE)

LABORATORY & PRODUCTION GRADE EQUIPMENT

Product Introduction
SPBM-8A is a compact laboratory and production-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-8A offers versatility for diverse research applications. Key specifications include a total volume of 8 L, four standard 2 L grinding jars, a net weight of 150 kg, overall dimensions of 880×560×642 mm, 1.5 kW motor power, adjustable planetary disk speed of 0–290 rpm, jar rotation speed of 0–580 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-8A 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 SPBM-8A mill requires the safety lock switch to be engaged before operation and overload protection to be active. Grinding jars and balls must be selected for material compatibility to avoid cross-contamination, and vacuum jar sealing must be verified for inert atmosphere grinding.

  • Safety Lock Engagement: The safety lock switch must be engaged before any grinding cycle begins.
  • Material Compatibility: Select grinding jar and ball materials that are compatible with the target sample to prevent cross-contamination.
  • Vacuum Jar Sealing: For vacuum atmosphere grinding, ensure the optional vacuum grinding jar is properly sealed before initiating the cycle.
  • Overload Protection: The mill's overload protection system automatically halts operation if electrical or mechanical overload is detected.
  • Power Supply Requirements: The mill requires a 220V/50Hz single-phase electrical supply with a 1.5 kW rated motor for proper operation.

This procedure describes the initialization and safe operation of the SPBM-8A mill for grinding experiments. Follow the steps below to ensure proper setup and safe grinding.

Required Equipment: ATOMFAIR SPBM-8A Planetary Ball Mill, Grinding Jars, Grinding Balls, Vacuum Grinding Jar (optional)

  1. Inspect Safety Lock
    Inspect the mill and confirm the safety lock switch is engaged before operation.
  2. Select Compatible Materials
    Select grinding jars and balls that are compatible with the target material to avoid cross-contamination.
  3. Verify Vacuum Jar Sealing
    If using vacuum atmosphere grinding, verify the optional vacuum jar is properly sealed before loading.
  4. Load Sample and Balls
    Load the sample material and grinding balls into the selected jars.
  5. Secure Jars on Platform
    Secure the loaded jars onto the four-station platform of the mill.
  6. Set Program Parameters
    Set the total grinding time between 1 and 9999 minutes and the bidirectional rotation interval between 1 and 999 minutes using the control panel.
  7. Start Grinding Cycle
    Start the grinding cycle and monitor the mill for normal operation.

Does the SPBM-8A's larger 8 L total volume reduce the maximum achievable grinding speed compared to smaller models, and what is the impact on particle size output?

Yes, the SPBM-8A has a lower maximum jar rotation speed of 580 rpm (revolution speed 0–290 rpm) compared to 870 rpm on the SPBM-0.4A, due to the larger jar capacity (1–2 L per jar). However, the fixed 1:2 revolution-to-rotation ratio and frequency conversion stepless speed regulation maintain consistent planetary motion, and the mill can still achieve minimum particle sizes down to 0.1 μm.

Can the SPBM-8A be used for wet grinding of air-sensitive materials, and what jar material is recommended to avoid contamination?

Yes, the SPBM-8A supports both dry and wet grinding processes. For air-sensitive materials, optional vacuum grinding jars up to 1500 mL can be used. Standard jar materials available include Al₂O₃, polyurethane, PTFE, ceramic, stainless steel, and nylon; the appropriate material should be selected based on chemical compatibility to avoid cross-contamination.

What are the electrical and physical installation requirements for the SPBM-8A, and what safety interlocks are integrated?

The SPBM-8A requires a 220V/50Hz single-phase power supply with a 1.5 kW motor. The unit weighs 150 kg and has overall dimensions of 880×560×642 mm. Safety features include a safety lock switch and overload protection; the lock must be engaged before operation to comply with laboratory safety standards.

The ATOMFAIR SPBM-8A (8 L total volume) vertical planetary ball mill delivers ultrafine grinding down to 0.1 μm with four-station parallel processing, but necessitates separate ordering of grinding jars and balls and optional vacuum jars for inert atmosphere applications.

Positive

  • Ultrafine grinding down to 0.1 μm: Planetary motion with revolution-to-rotation ratio of 1:2 delivers high energy density achieving minimum particle sizes of 0.1 μm for advanced material research.
  • Four-station parallel sample processing: Simultaneous preparation of up to four samples in a single experiment increases throughput for comparative studies in material science.

Trade-offs

  • Grinding media ordered separately: The main unit does not include grinding jars or balls; these consumables must be purchased separately with careful material compatibility selection to avoid cross-contamination.
  • Optional vacuum jars required for inert atmosphere: Vacuum or inert gas grinding capability requires purchase of optional vacuum grinding jars and proper sealing procedures before operation.
