The OPBM-20 requires adequate clearance around the equipment for safe 360° rotation of the overturning mechanism. Grinding jar and ball materials must be selected for compatibility with the target material to prevent cross-contamination.
- Clearance Requirement: The overturning mechanism requires adequate clearance space around the equipment for safe 360° rotation.
- Material Compatibility: Select jar and ball materials compatible with your target material to avoid cross-contamination.
- Maximum Loading Capacity: Do not exceed two-thirds of jar volume for material and grinding ball loading to prevent operational hazards.
- Feed Size Limit: Feed material must be ≤3 mm (≤10 mm for soil) to prevent jamming and damage to the mill.
- Pre-Operation Manual: Consult the user manual for detailed installation, operation, and maintenance instructions prior to first use.
How does the 360° overturning planetary disk improve grinding uniformity compared to conventional planetary ball mills?
The OPBM-20's 360° overturning planetary disk provides full 360° grinding coverage inside the jars, which eliminates common issues of material sedimentation and wall adhesion. This results in finer and more uniform powder compared to conventional planetary mills that only rotate in a fixed plane. The gear drive with inverter stepless speed regulation (0–430 rpm jar rotation) and a 4 kW motor further ensure consistent energy input across all four jars.
Which grinding jar materials are available for the OPBM-20 to avoid cross-contamination in high-purity milling?
The OPBM-20 supports grinding jars made from WC-Co, Al₂O₃, Agate, YSZ, SS, PU, Ceramic, and Nylon, each ordered separately. For zero-metal analysis, natural agate jars are recommended; for high-wear resistance and nano-grinding, WC-Co or YSZ jars are suitable. The jar volume per jar is 5 L (total 20 L), and the feed size is ≤3 mm (≤10 mm for soil), with discharge size down to 0.1 μm depending on material and process.
What safety and installation considerations are required for the OPBM-20's 360° overturning mechanism?
The overturning motor features brake locking, allowing the planetary disk to stop safely at any angle during operation. Adequate clearance space around the equipment is required for the full 360° rotation. The unit weighs 1180 kg with dimensions of 1700×1210×1300 mm, so floor loading capacity and access pathways must be evaluated prior to installation.
The OPBM-20 omnidirectional planetary ball mill utilizes a 360° overturning planetary disk to eliminate material sedimentation and wall adhesion, achieving finer powder uniformity. Its 4kW gear drive with inverter speed control and brake-locking overturn motor provides safe, precise operation, but jars and media are sold separately and adequate clearance is required for the overturning mechanism.
Positive
- 360° Overturning Grinding Coverage: The planetary disk rotates 360° during operation, providing full coverage inside jars to prevent material sedimentation and wall adhesion, resulting in finer and more uniform powder.
- Brake-Locking Overturn Motor: The overturning motor features brake locking, allowing the mill to stop safely at any angle, enhancing operator safety during loading and unloading.
Trade-offs
- Jars and Media Not Included: The listed price covers the main unit only; grinding jars and grinding balls must be ordered separately, which adds to the total cost and requires careful material compatibility selection.
- Clearance Space for Overturning: The overturning mechanism requires adequate clearance space around the equipment to safely perform the 360° rotation, which may limit placement in tight lab spaces.
