Description
Vertical Semi-Circular Planetary Ball Mill
Product Introduction
Planetary ball mill is a high-efficiency and precise laboratory-grade powder preparation equipment, mainly used for material crushing, mixing, dispersion and nanomaterial preparation. Its core structure consists of a planetary disk, ball milling jars (semi-circular or circular), grinding balls, drive system and safety devices. Through the composite motion of revolution and rotation of planetary wheels, combined with high-energy impact and friction, the equipment achieves efficient grinding of materials. The semi-circular ball milling jar design further optimizes space utilization and grinding efficiency, suitable for small-batch and high-precision experimental requirements.
Operating Principle of Planetary Ball Mill
The main disk of the planetary ball mill is equipped with four ball milling jars. When the motor drives the main disk to rotate, the ball milling jars revolve around the main disk shaft and rotate simultaneously driven by the planetary mechanism of the main disk, performing planetary motion. The grinding balls inside the jars rub and collide with each other during high-speed planetary motion, enabling efficient grinding and sample mixing.
Vertical semi-circular planetary ball mill is a device for mixing, fine grinding, small-sample preparation, new product development and small-batch production of high-tech materials. Our planetary ball mill features compact size, complete functions, high efficiency and low noise. It is an ideal powder equipment for research institutes, universities and enterprise laboratories to obtain research samples (four samples can be obtained simultaneously in each experiment). Equipped with vacuum ball milling jars, it can grind samples in a vacuum state.

Working Principle
- Planetary Motion Mechanism: The turntable drives the ball milling jars to revolve around the main shaft, while the jars rotate at high speed, forming a composite centrifugal force field.
- Grinding Effect: Grinding balls inside the jar collide with materials at high speed under centrifugal force, generating shearing, impact and friction forces to achieve crushing and mixing.
- Parameter Control: Precisely control finished product particle size by adjusting rotation speed (e.g. 200-800 rpm), grinding time and ball-to-material ratio.
Selection Guide
- Sample Properties: Wear-resistant jars (e.g., tungsten carbide) are required for hard materials; low-temperature grinding mode is optional for brittle or heat-sensitive materials.
- Processing Capacity: Choose single-jar or four-jar configuration according to experimental needs, with loading capacity not exceeding 2/3 of the jar volume.
- Grinding Objective: Nanoscale grinding requires high rotation speed (≥500 rpm) and small-sized grinding balls (e.g., zirconia balls).
- Equipment Parameters: Focus on motor power (e.g., 0.75-2.2 kW), maximum centrifugal acceleration and timing function.
- Safety & Maintenance: Prioritize models with automatic shutdown, fault alarm and easy disassembly design to reduce maintenance costs.

This equipment requires a well-ventilated laboratory environment with explosion-proof electrical systems due to the cryogenic liquid nitrogen and electrical motor hazards. The vacuum jars must be inspected for cracks before each use to prevent implosion or leakage of fine powders.
- Cryogenic Safety: Store liquid nitrogen in approved dewar containers and never seal the ball mill jars immediately after removal from cryogenic conditions to avoid pressure buildup.
- Electrical Safety: Ensure the power supply is grounded and the overload protection circuit is functional before operation.
- Mechanical Integrity: Inspect the planetary disk and jar holders for wear or deformation to prevent imbalance during high-speed rotation.
- Containment: Use only compatible jar materials such as stainless steel or ceramics and verify seals are intact to avoid sample leakage or cross-contamination.
- Temperature Management: Allow the mill to warm to room temperature after cryogenic operation before opening to avoid condensation and moisture ingress.
Proper initialization and operation ensure user safety and equipment longevity when handling cryogenic grinding. Follow these steps to load, operate, and unload the mill safely.
Required Equipment: Liquid Nitrogen Supply System, Vacuum Pump
- Inspect Jars and Seals
Inspect the ball mill jars and seals for cracks or wear before each use to ensure containment integrity. - Mount Jars Securely
Securely mount the filled jars onto the planetary disk and confirm the safety interlock is engaged to prevent accidental opening. - Set Parameters
Set the rotation speed and grinding duration using the intelligent control panel according to your material requirements. - Establish Cryogenic Conditions
Allow the mill to reach the desired cryogenic temperature via liquid nitrogen circulation before initiating rotation to avoid thermal shock. - Monitor Operation
Monitor the operation for abnormal vibrations or noise and stop immediately if any anomaly is detected. - Shutdown and Warm Up
After completion, shut down the system and allow the jars to warm to ambient temperature before opening to prevent condensation and pressure changes.
How does the -40°C low temperature capability of the XQM-1C affect the achievable particle size compared to standard ambient grinding?
Low-temperature grinding at -40°C minimizes thermal degradation of heat-sensitive materials while maintaining the ability to achieve particle sizes down to 0.1 micron, as the planetary motion (revolution + rotation) provides high energy density. The variable frequency speed regulation (0–1160 rpm on micro models) and forward/reverse alternating operation ensure uniform grinding even under cryogenic conditions.
Can the XQM-1C liquid nitrogen planetary ball mill accept standard vacuum ball milling jars for cryogenic grinding?
Yes, the XQM-1C is designed with vacuum tank adaptation and is fully compatible with vacuum ball milling jars, which are essential to prevent moisture condensation during cryogenic operation. The grinding jar clamping device accommodates jars made of stainless steel, ceramics, or polyurethane, all usable with liquid nitrogen.
What safety mechanisms are integrated into the XQM-1C to handle the risks associated with liquid nitrogen grinding?
The XQM-1C includes an emergency stop function, motor overload protection device, and safety switches, all complying with laboratory safety standards. The vacuum jar adaptation prevents pressure buildup from nitrogen gas expansion, and the low-noise design allows safe monitoring during operation.
The Atomfair XQM-1C combines planetary milling efficiency with cryogenic and vacuum capabilities, enabling sub-micron grinding of heat-sensitive and air-sensitive materials at laboratory scale. Its 1L capacity and liquid nitrogen requirement limit batch size and demand specialized cryogenic infrastructure.
Positive
- High-energy grinding to 0.1 micron: The planetary motion delivers high impact and friction energy, achieving uniform particle sizes down to 0.1 micron for advanced material preparation.
- Cryogenic and vacuum compatibility: Integrated liquid nitrogen cooling enables low-temperature grinding between -40°C and 20°C, and the vacuum jar adaptation supports inert-atmosphere processing of air-sensitive samples.
Trade-offs
- Requires external liquid nitrogen supply: Low-temperature operation depends on a continuous liquid nitrogen source, necessitating cryogenic handling equipment and strict safety protocols.
- Limited to 1L small-batch processing: The fixed 1L jar capacity restricts throughput to small-batch, high-precision laboratory applications, unsuitable for larger-scale production runs.
