Small Ball Mill XQM Series Powder Equipment Laboratory Planetary Ball Mill Equipped with Agate and Zirconia Jars

Product Description

The vertical square planetary ball mill is a powder processing device used for mixing, fine grinding, sample preparation, new product development, and small-batch production of high-tech materials. Our planetary ball mill features a compact size, full functionality, high efficiency, and low noise, making it an ideal choice for research institutes, universities, and enterprise laboratories to obtain experimental samples (up to four samples can be processed simultaneously in one run). When equipped with a vacuum milling jar, samples can be milled under vacuum conditions.

Structural Design

Square Body:
Formed by high-precision stamping molds, combining aesthetics and stability while effectively reducing vibration

Planetary Transmission System:
Planetary gears work with a sun gear to drive both revolution and self-rotation of the milling jars, improving grinding efficiency

Performance Advantages

High Efficiency Grinding:
Variable frequency speed control allows adjustment of rotation speed to meet different particle size requirements

Multi-functionality:
Supports dry grinding, wet grinding, vacuum grinding, and low-temperature grinding; compatible with various jar materials (e.g., stainless steel, alumina, zirconia)

Intelligent Control:
Equipped with an LCD touchscreen for programmable settings of grinding time, forward/reverse cycles, and speed; supports multi-task monitoring and data recording

Safety & Convenience

Safety Protection:
Electromagnetic door lock, door open/close protection switch, and anti-loosening nuts ensure safe operation at high speeds

Low Noise Design:
Gearbox uses solid lubrication or oil self-lubrication, reducing operating noise to below 60 dB

Working Principle

The vertical square planetary ball mill achieves efficient grinding through planetary motion:

Planetary Motion:
The main disk drives four jars to revolve around a central axis while each jar rotates in the opposite direction on its own axis, creating a compound motion

Grinding Mechanism:
Grinding balls inside the jars generate impact, shear, and friction during high-speed motion, crushing and mixing materials, suitable for dry/wet and vacuum environments

Particle Size Control:
By adjusting speed, grinding time, and ball ratio, materials can be reduced to nanoscale (~0.1 μm)

Selection Guide

Capacity Requirement

• Laboratory scale: 1–4 L equipment, suitable for 50 mL–1 L jars, ideal for sample preparation

• Production scale: ≥20 L equipment (e.g., XQM series), suitable for batch production, typically used with lifting and vibrating screening discharge systems

Material Selection

• Jar materials:

  • Stainless steel (anti-contamination)

  • Alumina (corrosion-resistant)

  • Zirconia (high hardness)

Control Method

• Prefer models with variable frequency speed control and programmable functions to improve experimental repeatability

Safety & Maintenance

• Pay attention to lubrication systems (e.g., oil self-lubrication) and gear durability to ensure long-term stable operation

Special Requirements

• For vacuum or inert gas grinding, optional vacuum jars and sealing systems are required
