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 powered mechanical equipment must be connected to a grounded 220V/110V supply and operated in a dry, ventilated laboratory to mitigate electrical hazards. The rotating planetary disk and ball milling jars create mechanical pinch points that require proper guarding and operator training.
- Electrical Safety: Inspect the power cord and plug for damage before each use and verify the outlet is properly grounded.
- Mechanical Guarding: Never operate the mill with any safety guard removed or interlock bypassed to prevent entanglement or impact injury.
- Overload Protection: Confirm the overload protection system is functional by running a test cycle after any maintenance or relocation.
- Jar Integrity: Examine ball milling jars for cracks, wear, or deformation before each run to prevent rupture under centrifugal stress.
- Environmental Storage: Store the equipment in a clean, temperature-controlled environment away from corrosive chemicals, moisture, and direct sunlight.
This procedure describes the safe initialization, operation, and shutdown of the planetary ball mill for grinding and mixing samples. Adherence to these steps reduces the risk of injury, equipment damage, and sample contamination.
Required Equipment: Planetary ball mill with control panel, Ball milling jars (compatible material), Grinding balls (material and size appropriate for sample), Personal protective equipment (safety glasses, gloves, lab coat)
- Inspect Equipment
Inspect the mill, jars, and grinding balls for any visible damage, cracks, or contamination before beginning the procedure. - Load Samples
Load the sample material and grinding balls into the jars, ensuring the total fill volume does not exceed two-thirds of the jar capacity. - Secure Jars
Secure the filled jars onto the planetary disk using the clamping mechanism and verify each jar is locked firmly in place. - Set Parameters
Set the rotation speed, total run time, and forward/reverse intervals using the LED control panel and confirm the values are within safe limits. - Engage Safety Guard
Close and latch the safety guard fully before powering the mill to prevent accidental contact with moving parts. - Start Operation
Start the mill by pressing the start button and monitor the first minute of operation for abnormal noise, vibration, or jar imbalance. - Stop and Retrieve
After the program ends, stop the machine, wait for all motion to cease completely, then open the guard and carefully remove the jars.
What is the trade-off between grinding speed and particle size uniformity when using the XQM-2C planetary ball mill for nanomaterials preparation?
The XQM-2C achieves uniform particle size down to 0.1 micron through planetary motion with variable speed control from 70 to 670 rpm. Higher speeds increase impact energy for faster size reduction, but the three-dimensional motion trajectory ensures uniform mixing across the full speed range. The variable frequency drive allows stepless speed adjustment to balance grinding time and final particle distribution for specific materials.
Can the Atomfair XQM-2C handle vacuum or inert atmosphere grinding for air-sensitive materials like lithium cobalt oxide?
Yes, the XQM-2C is compatible with vacuum ball milling jars, enabling sample grinding under vacuum or inert gas conditions. This makes it suitable for air-sensitive materials such as lithium cobalt oxide, lithium manganate, and other battery cathode precursors mentioned in the application scope. The vacuum jars prevent oxidation and contamination during high-energy milling.
What safety mechanisms prevent operator injury or mill damage during high-speed operation of the XQM-2C planetary ball mill?
The XQM-2C is equipped with motor overload protection, an emergency stop function, and a safety switch as standard. The low-noise design and CNC-machined precision gears ensure stable operation at high speeds. The grinding jar clamping device provides easy and secure locking to prevent jar detachment during operation.
The Atomfair XQM-2C vertical semi-circular planetary ball mill utilizes planetary motion for high-energy grinding of up to four samples simultaneously, supporting dry/wet grinding and vacuum jar compatibility for nanomaterials and small-batch R&D applications.
