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.

What is the trade-off between revolution and rotation speed when aiming for sub-micron particle size with the vertical semi-circular planetary ball mill?
The precise coordination of revolution and rotation speeds is essential to achieve uniform particle size down to 0.1 micron, as stated in the product description. Higher speeds increase grinding energy but require careful adjustment via the variable frequency drive to prevent motor overload and maintain consistency, especially for hard or heat-sensitive materials.
Can the XQM series planetary ball mill be used with vacuum ball milling jars for air-sensitive materials, and what jar materials are available?
Yes, the vertical semi-circular planetary ball mill is compatible with vacuum ball milling jars, enabling grinding in a vacuum state for air-sensitive samples. It also supports jars made of stainless steel, ceramics, and polyurethane, as listed in the product description, allowing integration with diverse chemical environments.
What safety and infrastructure requirements are needed for continuous high-speed operation of the vertical semi-circular planetary ball mill models (e.g., the XQM-6 with 100 kg net weight) to ensure laboratory compliance?
The equipment requires a stable support surface capable of handling at least 100 kg for models like the XQM-6 and must operate within noise control standards. It is built with motor overload protection, an emergency stop function, safety switches, and wide voltage adaptation to ensure stable, compliant continuous operation.
The XQM-8C vertical semi-circular planetary ball mill leverages high-energy planetary motion and three-dimensional grinding trajectories to achieve uniform particle size down to 0.1 micron, with variable frequency control and safety protection suitable for small-batch nanomaterial and ceramic research.
Positive
- High-Energy Planetary Motion: Planetary motion (revolution + rotation) provides high energy density, substantially improving grinding efficiency compared to conventional ball mills.
- Uniform Particle Size Down to 0.1 Micron: Three-dimensional motion trajectory ensures thorough mixing and uniform particle size distribution, enabling nanoscale powder preparation.
Trade-offs
- Mandatory Jar Material Selection: Compatibility with stainless steel, ceramic, and polyurethane jars requires users to select material that avoids cross-contamination with the sample, adding a preparatory step.
- Vacuum Grinding Requires Optional Jars: Vacuum ball milling jars are an accessory; standard operation does not provide vacuum capability, necessitating additional procurement for air-sensitive sample grinding.
