OPBM-40 360° ROTATING PLANETARY BALL MILL 5.5KW OMNIDIRECTIONAL

LABORATORY & PRODUCTION GRADE EQUIPMENT

Product Overview
The OPBM-40 is a mid-capacity laboratory and production-grade omnidirectional planetary ball mill for ultra-fine grinding and homogenization. With a 360° overturning planetary disk on its vertical planetary structure, it delivers full 360° grinding coverage inside jars to produce finer, more uniform powder and eliminates common issues of material sedimentation and wall adhesion. Powered by a 5.5kW drive system, it has a jar rotation speed of 0–390 rpm and a Φ430 mm jar orbit diameter, supports up to 4 simultaneous grinding jars with a 40L total maximum volume (10L per single jar), accepts feed sizes ≤3mm (≤10mm for soil) and achieves a final discharge size down to 0.1μm. It adopts gear drive with inverter stepless speed regulation, is equipped with a touchscreen control system featuring forward/reverse alternation, timing and power-off memory, and comes with a brake-locking overturn motor for safe stopping at any angle. With overall dimensions of 1900×1450×1480 mm and a net weight of 1430 kg, it is widely applicable to R&D and small-batch production across multiple industries; the listed price covers the main machine only, and grinding jars and media are available for separate order.

Product Features
  • Professional industrial exterior design with lean manufacturing and exquisite workmanship.
  • Machined parts adopt CNC technology; transmission gears are precision-made from special materials, ensuring stable, safe and low-noise high-speed operation.
  • The overturning motor features brake locking, allowing stopping at any angle safely and reliably.
  • Equipped with a microcomputer touch screen for convenient operation and a simple, intuitive interface.
  • Supports forward and reverse alternating control with timer and power-off memory functions.
  • Optional integrated microcomputer touch-screen PLC control panel.

PACKAGING: This listing is priced for the OPBM-40 main unit only. The standard configuration includes 1 pc grinding host machine with 360° overturning mechanism, gear drive transmission, and brand-name inverter speed control. Grinding jars and grinding balls are ordered separately. The OPBM series is available from 0.4 L through 100 L models. 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 overturning mechanism requires adequate clearance space around the equipment for safe 360° rotation. For detailed installation, operation, and maintenance instructions, consult the user manual prior to first use. If you have specific requirements for other OPBM models or custom configurations, please contact us at inquiry@atomfair.com.

The OPBM-40 planetary ball mill requires a stable, level surface that can support its 1430 kg weight and adequate clearance for the 360° overturning mechanism. Grinding jar and ball materials must be selected to be compatible with the target material, and the user must consult the user manual for all installation and operational safety instructions.

  • Clearance Requirement: Adequate clearance space around the equipment is required for safe 360° rotation of the overturning mechanism.
  • Material Compatibility: Grinding jar and ball materials must be chosen to be compatible with the target material to avoid cross-contamination.
  • User Manual: The user must review the full user manual for installation, operation, and maintenance instructions prior to first use.
  • Weight Support: The supporting surface must be capable of bearing the 1430 kg net weight of the machine.

How does the OPBM-40's 360° overturning mechanism improve grinding uniformity compared to conventional planetary ball mills?

The OPBM-40's 360° overturning planetary disk provides full 360° grinding coverage inside jars, producing finer and more uniform powder while eliminating common issues of material sedimentation and wall adhesion. This is achieved through the vertical planetary structure with a brake-locking overturn motor that allows safe stopping at any angle.

What jar materials are available for the OPBM-40 to prevent cross-contamination during ultra-fine grinding?

The OPBM-40 supports grinding jars in WC-Co, Al₂O₃, Agate, YSZ, SS, PU, Ceramic, and Nylon materials, each ordered separately. Selecting a jar material compatible with your target material is essential to avoid cross-contamination, as stated in the product's important notice.

What clearance space is required for safe operation of the OPBM-40's 360° overturning mechanism?

The OPBM-40 requires adequate clearance space around the equipment for safe 360° rotation of the overturning mechanism. The main unit dimensions are 1900×1450×1480 mm and it weighs 1430 kg, so installation planning must account for both the footprint and the rotational envelope.

The OPBM-40 planetary ball mill delivers 360° overturning planetary disk motion to eliminate sedimentation and wall adhesion, enabling finer and more uniform powder down to 0.1 μm. Its 5.5 kW gear drive with stepless speed regulation supports stable operation up to 390 rpm, but requires separate purchase of grinding jars and media with careful material selection to avoid contamination, and needs adequate clearance for safe 360° rotation.

Positive

  • 360° overturning eliminates sedimentation: The omnidirectional planetary disk rotates the grinding jars through 360°, preventing material sedimentation and wall adhesion, resulting in finer and more uniform powder compared to conventional planetary mills.
  • Robust gear drive with stepless speed control: A 5.5 kW gear drive with inverter-based stepless speed regulation provides stable, low-noise operation from 0–390 rpm, suitable for ultra-fine grinding down to 0.1 μm discharge size.

Trade-offs

  • Jars and media ordered separately: Grinding jars and media are not included with the main unit; users must select compatible materials (e.g., Al₂O₃, YSZ, agate) to avoid cross-contamination with the target sample.
  • Requires clearance for 360° rotation: The overturning mechanism needs adequate clearance space around the equipment to safely perform the full 360° rotation, which may constrain bench or floor layout.
