Product Overview
The MSK-SFM-15 is a high-speed laboratory planetary ball mill designed for advanced powder grinding, fine particle preparation, mechanical alloying, and material homogenization. Unlike conventional planetary ball mills with fixed speed ratios, the MSK-SFM-15 features independent speed control of sun-wheel revolution and milling jar self-rotation, allowing researchers to adjust milling conditions according to different materials, particle sizes, and processing requirements.
The sun-wheel revolution speed can be adjusted from 10 to 400 RPM, while the milling jar self-rotation speed ranges from 50 to 1600 RPM. This flexible speed control enables operators to modify the balance between impact and shear forces, making the equipment suitable for a wide range of laboratory applications, from powder mixing and homogenization to high-energy milling and particle size reduction.
Equipped with four planetary milling stations and a programmable touchscreen control system, the MSK-SFM-15 supports precise adjustment of operating speed, milling time, and multi-stage processing sequences. The controller can store up to 10 milling recipes, each containing up to 8 programmable speed segments, helping laboratories perform repeatable experimental procedures.
The referenced standard configuration includes four 500 mL stainless steel grinding jars and matching stainless steel milling balls. Additional milling jar materials, capacities, and specialized high-throughput accessories may be selected according to application requirements. The system is suitable for universities, battery research laboratories, materials science institutes, and industrial R&D facilities.

Independent Speed Control & Milling Performance
One of the main advantages of the MSK-SFM-15 is its independent control of revolution and self-rotation speeds. This enables researchers to select different combinations of planetary motion and jar rotation instead of relying on a fixed speed ratio. By adjusting both parameters, operators can modify the mechanical forces applied during milling and optimize processing conditions for specific materials.
Different revolution and rotation settings can influence powder movement, grinding media collisions, impact intensity, and shear action. Lower-energy conditions may be suitable for mixing or homogenization, while higher-energy settings may improve particle size reduction or mechanical alloying efficiency when used within the equipment’s permitted operating limits.
For high-speed milling, it is essential to follow the recommended loading limits. The total mass of samples and milling media must be reduced as operating speed increases. Dry milling also requires lower allowable loading than wet milling. Actual grinding performance depends on the sample properties, milling jar material, grinding ball size, sample-to-media ratio, and processing duration.
Grinding Jars & Accessories
The MSK-SFM-15 accommodates four milling stations and supports different grinding jar configurations to suit laboratory research requirements. The referenced package includes four 500 mL stainless steel jars and compatible stainless steel milling balls. Optional milling containers may be selected according to sample properties, contamination limits, required sample volume, and processing conditions.
- Stainless Steel Milling Jars: Suitable for many general-purpose laboratory grinding and metallic powder processing applications.
- Ceramic and Nonmetallic Jars: Selected alumina, zirconia, nylon, or other compatible materials may be used where metal contamination must be minimized.
- Vacuum-Compatible Milling Jars: Selected sealed or vacuum-compatible configurations may be available for specialized processing requirements.
- High-Throughput Accessories: Specialized multi-sample milling assemblies can improve experimental efficiency for material screening and small-volume sample preparation.
- Optional Larger Jars: Larger-capacity grinding jars, including options up to 2 L where supported, require verification of machine clearance, holding fixtures, permitted load, and operating speed.

Operating Guidelines & Safety Notes
- Balanced Jar Installation: Always install two jars in symmetrical positions with similar total weights or use four evenly balanced jars to maintain stable planetary rotation.
- Single-Sample Operation: When processing one sample, install an appropriately weighted counterbalance jar in the opposite position. Unbalanced loading may cause excessive vibration or mechanical damage.
- Wet Milling Load: Keep the total mass of samples and grinding media below 2000 g when revolution speed is below 350 RPM, and below 1000 g when revolution speed is below 400 RPM, according to the stated equipment limits.
- Dry Milling Load: The allowable total load for dry milling is approximately half of the corresponding wet milling limit.
- Jar and Media Compatibility: Select grinding containers and media according to material hardness, chemical compatibility, and acceptable contamination levels.
- Contamination Control: Where appropriate and safe for the material, conditioning a dedicated jar and grinding media with the same material may help reduce cross-contamination between milling batches.
- Ceramic Milling: For selected ceramic and oxide materials, use compatible nonmetallic jars and grinding media. Do not use stainless steel grinding balls inside alumina jars.
- Secure Jar Fixing: Check the jar locking fixtures and ensure all containers are correctly installed before starting the machine.
- Electrical Requirements: Confirm the supply voltage, current capacity, protective grounding, and suitable plug or hardwired connection before installation.
- Particle Size Results: Final particle size depends on sample characteristics, grinding media, rotational speed, milling duration, and operating conditions.
Configuration Note: Standard milling jars, grinding media, optional accessories, electrical connections, and certification documents should be confirmed in the final PENGXIN Machinery quotation. Larger jar options and high-throughput assemblies require compatibility verification. Technical specifications and achievable grinding results may vary according to the selected equipment configuration and material processing conditions.
