Description

SPBM-1A LATERAL PLANETARY BALL MILL (LABORATORY TYPE)

LABORATORY GRADE EQUIPMENT

Product Introduction
SPBM-1A 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-1A offers versatility for diverse research applications. Key specifications include a total volume of 1 L, four standard 250 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-1A 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-1A must be operated with the safety lock switch engaged and within the rated electrical supply of 220V/50Hz single-phase. Vacuum atmosphere grinding requires properly sealed optional vacuum grinding jars and inert gas supply.

  • Electrical Supply Constraint: The unit requires a 220V/50Hz single-phase grounded power supply with a 0.75 kW motor and overload protection.
  • Safety Interlock: The safety lock switch must be engaged before starting the grinding cycle.
  • Vacuum Sealing: For vacuum atmosphere grinding, ensure the optional vacuum grinding jar is properly sealed and connected to a vacuum source.
  • Jar Compatibility: Only use grinding jars within the 50–500 mL range and compatible materials (Al₂O₃, PU, PTFE, ceramic, SS, nylon) to avoid mechanical imbalance.
  • Speed Regulation: The planetary revolution speed must not exceed 335 rpm and jar rotation speed 810 rpm to maintain safe operation.

This procedure describes the initialization, loading, and safe operation of the planetary ball mill for ultrafine grinding. Follow these steps to ensure proper containment and avoid mechanical or electrical hazards.

Required Equipment: SPBM-1A main grinding unit, Grinding jars (50–500 mL, compatible material), Grinding balls (compatible material and size), Optional vacuum grinding jar

  1. Inspect and prepare the unit
    Inspect the unit for any damage and ensure the power cord is connected to a 220V/50Hz grounded outlet.
  2. Load jars and balls
    Select grinding jars and balls compatible with your material and load the jars with the sample and balls.
  3. Secure jars
    Secure the jars onto the four-station platform and verify the locking mechanism is engaged.
  4. Close and lock lid
    Close the safety lid and confirm the safety lock switch is activated.
  5. Set grinding parameters
    Set the desired grinding time, speed, and bidirectional rotation intervals on the programmable control panel.
  6. Start grinding cycle
    Press the start button to begin the grinding cycle and monitor the operation.
  7. Stop and retrieve samples
    Allow the unit to stop completely before opening the lid and removing jars.

How does the fixed 1:2 revolution-to-rotation ratio of the SPBM-1A affect its grinding performance compared to variable-ratio planetary ball mills?

The fixed 1:2 ratio (revolution speed 0–335 rpm, jar speed 0–810 rpm) delivers a consistent high-energy density and three-dimensional movement trajectory, achieving ultrafine grinding down to 0.1 μm. This fixed ratio simplifies process reproducibility but offers no tunability for material-specific energy input; for applications requiring different impact-to-friction ratios, the SPBM-1A cannot adjust the ratio without changing the model.

What jar and ball material options are available for the SPBM-1A, and how should researchers select combinations to prevent cross-contamination?

The SPBM-1A supports jar materials including Al₂O₃, PU, PTFE, ceramic, stainless steel, and nylon, and ball materials including WC-Co, Al₂O₃, PU-Fe, agate, YSZ, HCCI, and 304SS, all ordered separately. Researchers must select jar and ball materials chemically compatible with the target sample to avoid contamination; for example, use agate for silica-free grinding or YSZ for high-wear-resistance applications. The mill can run both dry and wet processes with any of these materials.

What infrastructure and safety measures are required for vacuum atmosphere grinding with the SPBM-1A?

The SPBM-1A supports vacuum grinding only with optional 50–250 mL vacuum grinding jars and requires a safety interlock that must be engaged before operation. The mill operates on 220V/50Hz single-phase power with a 0.75 kW motor, and the safety lock switch and overload protection must be verified prior to use. For air-sensitive materials, the vacuum jar must be properly sealed before initiating the grinding cycle to maintain inert atmosphere integrity.

This compact lateral planetary ball mill offers high-energy compound planetary motion for ultra-fine grinding down to 0.1 μm, with variable frequency drive and programmable cycles. However, jars and media are sold separately, and jar loading is limited to two-thirds capacity, requiring careful planning for lab deployment.

Positive

  • High grinding efficiency and fine particle size: Compound planetary motion delivers high energy density, achieving minimum output particle size down to 0.1 μm with narrow size distribution, superior to traditional milling equipment.
  • Intelligent programmable control: Variable frequency stepless speed regulation, timing (1–9999 min), forward-reverse cycle (1–999 min), and LED digital display enable precise, repeatable operation for diverse protocols including dry and wet grinding.

Trade-offs

  • Jars and grinding media not included: The main unit is sold without grinding jars or balls; these must be ordered separately based on material compatibility, adding upfront procurement steps and cost.
  • Limited jar loading capacity: Maximum jar filling is two-thirds of jar volume per the manufacturer's instruction, constraining batch size and requiring careful charge calculation to avoid overloading.
