With BM6Pro, BM20, BM40, and BM20Plus models, labs can match capacity, speed, and throughput needs to real-world sample preparation workflows. As a Top Brand and Trusted Brand in the field, we provide the technology required to achieve nano-level fineness across diverse industrial applications.
Planetary Ball Milling for Mining, Metallurgy, and Cement Sample Preparation
Grinding and mixing dry or wet materials requires equipment that can maintain strict standards of fineness. The BM Series allows laboratories to achieve analysis-ready powders through high-energy impacts and friction. These mills are built to provide the reproducible results needed for precision and consistency in high-stakes testing environments. Advanced workflows also benefit from the colloidal grinding readiness of these units, enabling the production of extremely fine dispersions and mixtures.
Sample Types and Typical Materials Processed
The BM Series handles soft, hard, brittle, and fibrous samples with equal efficiency. Typical materials processed in mining, metallurgy, and cement sectors include:
- Cement clinker, concrete, limestone, gypsum, and quartz
- Metal oxides (including iron ore), metals, and carbon fiber
- Ceramics, bentonite, and other mineral components
- Glass and various geological specimens
The BM series supports broad cross-industry sample preparation, providing the versatility needed for geology and metallurgy labs that handle varied material compositions.

- Multiple grinding stations: configurations available with 1, 2, or 4 stations depending on volume needs
- Multi-sample processing: the BM40 model supports processing 2, 4, or 8 samples simultaneously
- Wide jar selection: includes six different jar types with volumes ranging from 12 mL to 4000 mL
- Diverse jar materials: available in agate, aluminum oxide, zirconium oxide, and tungsten carbide to prevent cross-contamination
Advanced Monitoring and Safety for Wet and Colloidal Grinding
- Integrated monitoring system: tracks internal pressure and temperature to manage safe operation during high-energy runs
- Automatic ventilation: maintains jar cooling through dedicated airflow and high-power motor cooling fans
- Intelligent security: incorporates security locks and gas-tight, dust-proof closures to protect the operator and the environment
Practical Grinding Setup Examples
- Glass: uses zirconium oxide balls (10 mm and 3 mm) for 30 minutes to process this hard sample type
- Granite: utilizes stainless steel balls (10 mm) for 15 minutes to achieve the desired fineness
- Pearl powder: requires zirconium oxide balls (3 mm) for 6 hours; liquid must be added properly to handle this brittle material
Grinding jars must be placed symmetrically to maintain balanced operation and protect the drive system.

How a Planetary Ball Mill Works
The sun wheel drives the grinding jars in a circular path. The jars rotate on their own axes while revolving in the opposite direction around the sun wheel. This dual motion creates strong Coriolis forces and high impact energy. The grinding balls continuously impact and crush the samples against the jar walls, resulting in rapid size reduction.
Customizable Speed Ratio for Tailored Energy Input
Laboratories can choose between 1, 2, or 4 stations depending on their specific batch volume requirements. The speed ratio (typically between 1:1 and 1:3.5) controls the energy input and final grinding outcomes. Selecting the correct jar material and ball size based on sample hardness and contamination sensitivity is necessary for successful sample preparation.
