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.

Required Equipment: Planetary ball mill, Vacuum ball milling jar, Liquid nitrogen cooling system
- Inspect and verify safety
Inspect the planetary ball mill for any damage and verify that all safety switches are operational before loading materials. - Load materials and balls
Load the grinding balls and sample material into the vacuum ball milling jar, ensuring proper fill volume. - Secure jar and connect cooling
Secure the jar onto the planetary disk and connect the liquid nitrogen cooling system if low-temperature grinding is required. - Set grinding parameters
Set the desired rotation speed, grinding time, and forward/reverse intervals using the intelligent control panel. - Start and monitor operation
Start the ball mill and monitor the operation for any abnormal noise or vibration throughout the grinding cycle. - Safe shutdown and removal
After the cycle completes, turn off the power and allow the jar to warm to room temperature before removing it.
Does liquid nitrogen cooling in the XQM-12C compromise grinding energy transfer compared to ambient temperature operation?
Yes, cryogenic conditions reduce material ductility and slow diffusion-limited reactions, but the planetary ball mill’s high-energy impact and friction mechanism still achieves particle sizes down to 0.1 micron. The variable frequency drive and precisely coordinated revolution-rotation speeds compensate for the increased viscosity of lubricants and maintain efficient comminution at temperatures as low as -40°C.
Can the XQM-12C accommodate both vacuum and inert gas conditions without modifying the jar sealing mechanism?
Yes, the vacuum ball milling jars are engineered to maintain a hermetic seal under both vacuum and positive inert gas pressure. The same sealing system, compatible with jars made from stainless steel, ceramics, or polyurethane, preserves atmospheric control without retrofitting, enabling direct switching between vacuum grinding and argon or nitrogen backfill operations.
What specific safety measures are required when operating the XQM-12C with liquid nitrogen coolant?
The built-in overload protection device and emergency stop function remain fully operational, but the liquid nitrogen system demands proper insulation of the cooling jacket and venting to prevent overpressure. The low-noise design and CNC-machined components ensure stable operation within the -40°C to 20°C range, while the grinding jar clamping device must be checked for frost buildup to maintain secure fastening during cryogenic cycling.
The Atomfair XQM-12C is a 12-liter planetary ball mill engineered for cryogenic grinding from -40°C to 20°C using liquid nitrogen cooling, and supports vacuum operation for air-sensitive materials.
