Description
Heavy-Duty Horizontal Planetary Ball Mill
Product Introduction
The heavy-duty horizontal planetary ball mill adopts a dual-disk support bracket structure at both ends, which effectively improves equipment stability and load-bearing capacity, overcoming the limitation that light-duty horizontal planetary ball mills are only suitable for light-load applications. This machine is mainly intended for pilot-scale tests or small-batch grinding production.
Operating Principle of Planetary Ball Mill
The main disk of the planetary ball mill is equipped with four grinding jars. As the motor drives the main disk to rotate, the jars revolve around the main disk shaft while rotating on their own under the drive of the planetary mechanism, forming a planetary motion. The grinding balls inside the jars rub and collide with each other during high-speed planetary movement, enabling efficient grinding and sample mixing.

Working Principle
The heavy-duty horizontal ball mill drives grinding media and materials through the rotation of a horizontal cylinder:
- Cylinder Rotation: The motor, via a reducer, rotates the cylinder around a horizontal axis. Grinding media (steel balls, etc.) inside rise along the cylinder wall to a certain height and then fall freely.
- Grinding Effect: Falling media impact and crush materials, while friction and shearing between materials and media further refine particles.
- Classified Discharging: Materials are ground stage by stage through multi-compartment diaphragms and finally discharged through a grid, realizing continuous production.
Selection Guide
Capacity Requirements
Select cylinder volume based on output: 50L–500L for small-scale production, and above 1000L (e.g., 5000L-class equipment) for large industrial lines.
Material Characteristics
- High-hardness materials require highly wear-resistant linings (e.g., manganese steel or zirconia) and large-sized grinding media.
- Wet grinding needs corrosion-resistant cylinders and sealed structures.
Energy Consumption & Maintenance
- Prioritize models with rolling bearings and variable frequency speed control to reduce energy consumption and improve control accuracy.
- Regularly inspect lining wear and lubrication systems for long-term stable operation.
Special Requirements
- For ultra-fine powders (≤1μm), a forced stirring system or counter-rotating device is recommended to enhance grinding efficiency.
For industries with high cleanliness requirements (pharmaceuticals, food, etc.), full stainless steel structure and pollution-free linings are required.
The dual-disk support bracket and heavy weight demand placement on a level, reinforced surface capable of supporting up to 1070 kg. The brake locking mechanism must be engaged before any jar lifting or loading to prevent unintended rotation.
- Electrical Supply Compatibility: Ensure the power supply matches the motor specification of 7.5 kW and includes proper grounding and overload protection.
- Jar Handling Safety: Always engage the brake lock prior to installing or removing grinding jars to prevent the main disk from moving.
- Vibration and Stability: Operate the mill on a vibration-dampening pad to minimize transmitted vibrations and maintain alignment of the dual-disk support structure.
This procedure outlines the safe steps to initialize the mill, load grinding jars, and operate the machine for wet or dry grinding. Follow the chronological steps to ensure secure jar mounting and controlled operation.

Activate the brake locking function to secure the main disk before attempting any jar installation. - Mount Grinding Jars
Use the integrated lifting device to carefully position the filled grinding jars onto the jar holders and lock them in place. - Set Operating Parameters
Program the desired rotation speed, grinding time, and direction (forward or reverse) using the microcomputer touch screen interface. - Start Grinding Cycle
Initiate the grinding cycle and monitor the display for real-time speed and remaining time; the power-off memory will preserve settings if interrupted. - Stop and Discharge
After the cycle completes, allow the mill to come to a full stop before disengaging the brake lock. - Unload Material
Activate the vibrating screen discharging device to quickly and efficiently empty the ground material from the jars.
How does the jar rotation speed range of 0–310 rpm on the WXQM-60 impact its suitability for ultra-fine powder grinding below 1 μm?
The WXQM-60's maximum jar speed of 310 rpm with a 1:1.5 gear ratio provides sufficient centrifugal force for planetary motion, but for ultra-fine powders (≤1 μm) the selection guide recommends a forced stirring system or counter-rotating device to enhance grinding efficiency. This means the standard configuration may require optional accessories to achieve submicron particle sizes.
What material or lining compatibility issues must be considered when using the WXQM-60 for grinding high-hardness ceramics like alumina or zirconia?
For high-hardness materials such as alumina or zirconia ceramics, the WXQM-60 requires highly wear-resistant linings like manganese steel or zirconia and large-sized grinding media. Additionally, if wet grinding is performed, corrosion-resistant cylinders and sealed structures are necessary to prevent contamination and equipment damage.
What infrastructure and safety measures are necessary to install and operate the 1070 kg WXQM-60 horizontal planetary ball mill?
The WXQM-60 has a net weight of 1070 kg and dimensions of 1980×1050×1220 mm, requiring a reinforced floor capable of supporting concentrated loads. The equipment includes a brake locking function for safe jar handling during lifting, loading, and locking, and an integrated lifting and discharging device with vibrating screen technology to improve production efficiency and operator safety.
The Atomfair WXQM-60 heavy-duty horizontal planetary ball mill is designed for pilot-scale and small-batch grinding, featuring a dual-disk support bracket structure for enhanced stability and load capacity, along with an integrated lifting and vibrating screen discharging system to improve handling efficiency. However, achieving ultra-fine powders (≤1 μm) may require optional forced stirring or counter-rotating attachments, and high-hardness materials demand specialized wear-resistant linings.
