Product Overview
The MSK-SFM-13 is a high-capacity laboratory planetary ball mill designed for efficient grinding, fine powder preparation, mixing, and homogenization of various materials. Featuring four planetary milling stations with a combined nominal jar capacity of 12 liters (4 × 3L), the system is suitable for laboratory research, pilot-scale material preparation, and experimental powder processing.
The planetary milling mechanism combines the revolution of the main plate with the self-rotation of the grinding jars to generate centrifugal forces for effective material processing. This design promotes uniform mixing, particle size reduction, and repeated interaction between the grinding media and sample materials.
The MSK-SFM-13 features a digital variable-frequency speed controller, adjustable milling and rest periods, and bidirectional rotation settings. The main plate revolution speed ranges from 30 to 300 RPM, while the milling jars rotate at approximately 70 to 580 RPM, providing flexible operating conditions for different materials and grinding requirements.
The referenced equipment configuration includes four 3L nylon grinding jars and zirconia grinding balls. Additional compatible milling jar materials and accessories may be selected according to sample characteristics and processing requirements. This system is widely applicable to geology, mining, metallurgy, ceramics, electronic materials, chemical engineering, battery materials research, and industrial laboratory applications.

Operating Guidelines & Application Notes
- Jar and Media Compatibility: Select grinding jars and milling balls according to the hardness, chemical properties, and contamination requirements of the sample.
- Balanced Jar Loading: Arrange milling jars symmetrically and maintain balanced total weights to support stable planetary rotation.
- Feed Material Preparation: Reduce the initial particle size where necessary to improve milling efficiency and reduce unnecessary mechanical stress.
- Milling Parameters: Adjust rotational speed, grinding time, rest intervals, and grinding media according to the material and target particle size.
- Temperature Management: Extended milling can generate heat. Use suitable rest periods and compatible cooling accessories when additional temperature control is required.
- Maximum Operating Time: Follow the recommended operating period and equipment instructions. The stated maximum working period is 48 hours under suitable conditions.
- Grinding Performance: Final particle size depends on material properties, feed size, milling jar selection, ball-to-powder ratio, operating speed, and milling duration.
