The HPBM-20 is a heavy-duty 4kW horizontal planetary ball mill with a braking safety function and touch control. All milling operations require securely clamped grinding jars and proper brake engagement to prevent mechanical hazard.
- Jar Securement Constraint: Grinding jars must be securely clamped in the 200 mm inner diameter jar holders before starting rotation to avoid imbalance and ejection.
- Brake Locking Requirement: The brake locking safety function must be engaged before opening the screen discharging mechanism or accessing the milling chamber.
- Ball Charge Constraint: Grinding balls should fill approximately 40% of the jar volume to maintain optimal milling dynamics and prevent overloading.
- Power Supply Requirement: The 4kW motor requires a dedicated electrical circuit with appropriate overcurrent protection and grounding.
- Material Containment Constraint: Compatible jar materials (WC-Co, Al2O3, agate, YSZ, SS, PU, ceramic, nylon) must be selected to avoid chemical contamination or reaction with the sample.
This procedure describes the safe initialization and operation of the HPBM-20 heavy-duty horizontal planetary ball mill. Follow these steps to set up grinding jars, add media, start the mill, and discharge milled material.
Required Equipment: Grinding jars (Al2O3, YSZ, agate, etc.), Grinding balls (WC-Co, Al2O3, agate, YSZ, SS)
- Secure Grinding Jars
Place the grinding jars into the 200 mm jar holders and clamp them firmly to prevent movement during rotation. - Load Grinding Media and Sample
Fill each jar to approximately 40% volume with grinding balls and add the material to be milled, leaving headspace for grinding action. - Close and Tighten Jar Lids
Securely close and tighten the lids of all jars to prevent leakage and ensure containment. - Set Operating Parameters
Use the microcomputer touch panel to set desired rotation speed (0–430 rpm), forward/reverse cycles, and milling time. - Confirm Brake Disengaged and Start Mill
Ensure the brake locking function is disengaged, then press start to begin the milling cycle. - Monitor and Stop Mill
Monitor the operation; after the programmed time, the mill will stop automatically; allow it to come to a complete halt. - Discharge Milled Material
Engage the brake locking function, activate the integrated lifting and screen discharging mechanism, and collect the milled powder.
How does the 0.086 drive ratio of the HPBM-20 affect grinding performance compared to higher-ratio models like the HPBM-16?
The HPBM-20's 0.086 drive ratio, combined with a 4 kW motor and 0–430 rpm jar speed, delivers higher torque at lower rotational speeds compared to the HPBM-16's 0.096 ratio and 3 kW motor. This trade-off prioritizes stable, high-load grinding for larger jar capacities (200 mm ID holders) and heavier batches (730 kg net weight) over maximum jar speed, making it suitable for pilot-scale production of dense materials like lithium battery cathodes or electronic ceramics.
Can the HPBM-20 be integrated with 5 L grinding jars made of WC-Co or YSZ for contamination-free milling of hard materials?
Yes, the HPBM-20 accepts 5 L grinding jars in materials including WC-Co, YSZ, Al₂O₃, agate, stainless steel, PU, ceramic, and nylon, all ordered separately. For hard materials like cemented carbides or zirconia, WC-Co or YSZ jars paired with matching grinding balls (e.g., WC-Co or YSZ media) minimize cross-contamination and maximize wear resistance, though the 200 mm jar holder inner diameter and 385 mm revolution orbit must accommodate the selected jar geometry.
What safety and infrastructure requirements are needed for operating the 730 kg HPBM-20 with its integrated lifting and brake locking mechanism?
The HPBM-20 requires a reinforced floor capable of supporting its 730 kg net weight and 1640×840×1040 mm footprint, plus a 4 kW electrical supply. Its integrated lifting and screen discharging mechanism with brake locking safety function prevents accidental jar release during operation, but users must ensure adequate clearance for the dual-end double disc support frame and access to the microcomputer touch control for forward-reverse cycling and power-off memory recovery.
The HPBM-20 is a 4 kW heavy-duty horizontal planetary ball mill featuring a dual-end double disc support frame for enhanced rigidity, integrated lifting and screen discharging with brake locking, and microcomputer touch control. Its operational deployment requires separate purchase of grinding jars and media, and the 730 kg net weight necessitates robust floor infrastructure.
Positive
- Heavy-duty rigid frame construction: Dual-end double disc support frame greatly boosts overall rigidity, load capacity, and operational stability compared to light horizontal planetary mills.
- Integrated discharge and control system: Integrated lifting and screen discharging mechanism with brake locking safety function, plus microcomputer touch control with forward-reverse cycle, timing, and power-off memory for flexible and safe operation.
Trade-offs
- Grinding jars and media sold separately: Grinding jars and grinding balls are not included with the main unit and must be ordered separately, increasing initial setup complexity and cost.
- High net weight requires robust support: At 730 kg net weight, the unit demands substantial floor loading capacity and specialized handling equipment for installation and relocation.
