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.
Product Application
Heavy-duty horizontal planetary ball mills are widely used in geology, mineral resources, metallurgy, electronics, building materials, ceramics, chemical industry, light industry, medicine, environmental protection and other fields.They are suitable for the production of electronic ceramics, structural ceramics, magnetic materials, lithium cobalt oxide, lithium manganate, catalysts, fluorescent powders, long afterglow luminescent powders, rare earth polishing powders, electronic glass powders, fuel cells, zinc oxide varistors, piezoelectric ceramics, nanomaterials, wafer ceramic capacitors, MLCC, thermistors (PTC, NTC), dielectric ceramics, alumina ceramics, zirconia ceramics, zinc oxide powder, cobalt oxide powder, Ni-Zn ferrites, Mn-Zn ferrites and other materials.
Product Features
The equipment features a professional industrial exterior design. The casing is welded with thickened steel plates, delivering high strength, impact resistance, deformation resistance and a robust appearance. Machined parts undergo strict heat treatment and CNC processing. Transmission gears are precision-made from special materials, ensuring stable, safe and low-noise operation at high speeds.The machine is equipped with a brake locking function to guarantee safe operation during jar lifting, loading and locking. The integrated lifting and discharging device incorporates vibrating screen discharging technology, enabling quick jar handling, unloading and charging to improve production efficiency.A microcomputer touch screen is adopted for easy and intuitive operation. It supports forward and reverse alternating control, timing function and power-off memory.

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 mill requires electrical grounding and circuit protection rated for the 1.5 kW motor to prevent shock or fire hazards. The brake locking function must be engaged during jar loading and unloading to avoid injury from rotating components.
- Electrical Grounding Requirement: The mill must be connected to a properly grounded outlet and circuit protection rated for the motor power.
- Jar Locking Procedure: Always engage the brake locking function before loading or unloading the grinding jars to prevent rotation.
Follow these steps to load jars, set parameters, and safely run a grinding cycle. Always wear appropriate PPE and ensure the area is clear of obstructions.
Required Equipment: Planetary ball mill with control panel, Grinding jars with locking mechanisms, Integrated lifting and discharging device
- Prepare Mill

Place the filled grinding jars into the holders and verify they are firmly seated. - Close and Unlock
Close the lid and disengage the brake lock to prepare for rotation. - Set Parameters
Set the rotation speed and grinding time on the microcomputer touch screen, selecting forward/reverse control if needed. - Start Grinding
Press the start button to begin the grinding cycle and monitor operation through the display. - Stop Mill
Allow the mill to complete the grinding cycle and come to a full stop automatically. - Unload Jars
Engage the brake lock, open the lid, and use the lifting device to remove the jars for unloading.
What is the trade-off between motor power and achievable jar rotation speed in the Atomfair WXQM-(2-6)(H) compared to the standard WXQM-(2-6)?
The WXQM-(2-6)(H) uses a 1.5 kW motor while the standard WXQM-(2-6) uses a 0.75 kW motor, yet both achieve the same jar rotation speed range of 0–670 rpm. The higher motor power in the (H) model provides greater torque for heavy-duty loads without sacrificing maximum speed, but increases net weight from 96 kg to 266 kg and overall dimensions to 1220×620×810 mm.
What grinding jar sizes are compatible with the WXQM-(2-6)(H) planetary ball mill?
The WXQM-(2-6)(H) has a jar holder inner diameter of 134 mm, accommodating jars of that diameter. The main disk supports four grinding jars per batch, making it suitable for pilot-scale grinding of materials such as lithium cobalt oxide, catalysts, and alumina ceramics as listed in the intended applications.
What safety features does the Atomfair WXQM-(2-6)(H) include for jar handling and operation?
The mill is equipped with a brake locking function to ensure safe operation during jar lifting, loading, and locking. It also features an integrated lifting and discharging device with vibrating screen discharging technology for quick and secure jar handling, improving overall operational safety.
Atomfair WXQM-(2-6)(H) heavy-duty horizontal planetary ball mill with 1.5kW motor and double-disk support structure provides enhanced stability for pilot-scale and small-batch grinding, supporting jar speeds up to 670 rpm. The integrated lifting and vibrating screen discharging system improves material handling efficiency, while the microcomputer touch screen enables precise control with forward/reverse and power-off memory.
Positive
- Dual-disk support for heavy loads: The double-disk support bracket structure improves equipment stability and load-bearing capacity, overcoming light-duty limitations and enabling pilot-scale and small-batch grinding.
- Integrated vibrating screen discharging: The built-in lifting and discharging device with vibrating screen technology accelerates jar handling, unloading, and charging, increasing overall production efficiency.
Trade-offs
- Ultra-fine grinding requires add-ons: For achieving particles ≤1 μm, a forced stirring system or counter-rotating device must be added, as the base mill lacks this capability.
- Routine maintenance demands: Regular inspection of lining wear and lubrication systems is required to ensure long-term stable operation, adding to operational overhead.
