Description

Vertical Semi-Circular Planetary Ball Mill

Product Introduction

A planetary ball mill is a high-efficiency and precise laboratory-grade powder preparation device, 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, a drive system, and safety devices. Through the composite motion of revolution and rotation of the 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, making it 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 simultaneously rotate under the drive of the main disk’s planetary mechanism, 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.

The vertical semi-circular planetary ball mill is a device used for mixing, fine grinding, small-sample preparation, new product development, and small-batch production of high-tech materials. Our planetary ball mill features a 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 the finished product particle size by adjusting the 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; the low-temperature grinding mode is optional for brittle or heat-sensitive materials.
Processing Capacity: Choose a single-jar or four-jar configuration according to experimental needs, with the loading capacity not exceeding 2/3 of the jar volume.
Grinding Objective: Nanoscale grinding requires a 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.

Constraints

The device requires proper electrical grounding and use of integrated safety locks to prevent operation during maintenance. Grinding must be performed within rated jar capacity and rotation speed limits to avoid mechanical overload.

Electrical Safety: The 4KW motor demands a dedicated grounded power outlet and must not be operated with damaged cables or in wet conditions.
Mechanical Safety: All ball milling jars must be securely locked onto the planetary disk before starting the drive to prevent ejection during high-speed revolution.
Vacuum Operation: When using vacuum jars, verify that all seals are intact and the vacuum pump is correctly connected to avoid leakage and sample contamination.
Speed Control: Do not exceed the manufacturer's maximum rotational speed for the selected jar size to prevent bearing overload or jar rupture.
Jar Selection: Use only jars and grinding balls made of compatible materials for the sample to avoid chemical reactions or mechanical wear compromising integrity.

FAQ

How does the planetary motion of the XQM-20 affect achievable particle size distribution, and what is the trade-off between grinding efficiency and jar material wear?

The XQM-20 achieves particle sizes down to 0.1 micron through its high-energy planetary motion combining revolution and rotation for high energy density. However, optimal grinding efficiency for hard materials like ceramics may require longer cycles or reduced speeds to minimize wear on softer jar materials such as polyurethane, while stainless steel jars offer greater durability for extended high-speed runs.

Can the Atomfair XQM-20 be used for vacuum or inert atmosphere grinding, and what jar materials are recommended to avoid contamination when processing air-sensitive materials like lithium cobalt oxide?

Yes, the XQM-20 supports vacuum grinding when equipped with vacuum ball milling jars, enabling inert atmosphere processing for air-sensitive materials such as lithium cobalt oxide or fuel cell catalysts. The mill is compatible with jars made of stainless steel, ceramics, and polyurethane, allowing selection based on chemical compatibility and contamination risk for high-purity applications.

What are the infrastructure and safety requirements for operating the XQM-20 4 kW planetary ball mill in a laboratory setting?

The XQM-20 requires a standard electrical supply for its 4 kW motor and must be used with safety switches, overload protection, and an emergency stop button to meet laboratory safety standards. Its low-noise design complies with noise control regulations, and the semi-circular jar clamping device ensures secure mounting during high-speed planetary motion to prevent jar displacement.

Assessment

The XQM-20 planetary ball mill delivers high-energy planetary motion for grinding to sub-micron particle sizes (down to 0.1 micron), with variable frequency speed control and support for dry/wet milling. Its vertical semi-circular design and 4kW motor allow processing of up to four samples per batch, making it ideal for small-batch R&D but not suited for large-scale continuous production.

Positive

High energy-density grinding efficiency: The planetary motion (revolution + rotation) provides high energy density, significantly improving grinding efficiency compared with traditional equipment, enabling faster processing of hard materials.
Achieves uniform sub-micron particle distribution: Three-dimensional motion trajectory ensures thorough mixing and a uniform particle size distribution down to 0.1 micron, which is critical for advanced materials research and quality control.

Trade-offs

Limited to small-batch processing: The machine is designed for small-batch production (up to four samples per experiment) and is not intended for large-scale or continuous processing, which may require multiple runs for larger volumes.
Requires careful jar and media selection: While compatible with jars of various materials (stainless steel, ceramics, polyurethane), the user must select appropriate jar and ball materials to avoid contamination or chemical incompatibility with the sample.
