MSK-SFM-30L 30L Planetary Vacuum Mixer with Integrated Vacuum Pump and Temperature-Controlled Water Chiller for Uniform Slurry Mixing
The MSK-SFM-30L is engineered to address the challenges of mixing high-viscosity slurries requiring uniform dispersion and minimal air entrapment. It is particularly suited for preparing advanced battery materials such as lithium cobalt oxide (LiCoO2), lithium iron phosphate (LiFePO4), nickel-cobalt-manganese (NCM) compounds, and ceramic slurries. The system’s vacuum capability ensures effective removal of entrapped gases, enhancing slurry quality and consistency.
This planetary mixer employs a combination of revolution and rotation movements via dual planetary stirring shafts, complemented by a scraping blade that continuously cleans the container walls to prevent dead zones. The stainless steel mixing container has an effective volume of 30 liters and is jacketed for water cooling, enabling precise temperature control between 35ºC and 50ºC through the included digital recirculating water chiller. This temperature regulation supports optimal slurry properties during mixing.
Key Features
- Dual planetary stirring shafts with independent rotation and revolution for thorough mixing and dispersion.
- PTFE scraping blade rotates with the main shaft to eliminate dead corners and ensure uniform slurry consistency.
- Heavy-duty double-stage vacuum pump included, achieving vacuum levels up to -0.098 MPa to remove entrapped air.
- Hydraulic lifting system with 300 mm maximum lift height for easy bucket handling.
- Stainless steel 304 mixing container with 6 mm inner wall thickness and water cooling jacket for temperature control.
- Integrated digital temperature-controlled recirculating water chiller with 6-liter tank and 16 L/min flow rate.
- Multiple fittings including DN50 feed hole, ball valve outlet, sight glasses, vacuum connectors, and vacuum meter for operational convenience.

Typical Applications
The MSK-SFM-30L is widely used in battery research and production for mixing cathode and anode slurries, including LiCoO2, LiFePO4, and NCM materials. It is also suitable for ceramic slurry preparation and other applications requiring high-viscosity material mixing under vacuum to ensure homogeneity and air bubble removal.
Configuration & Operating Notes
The system includes a hydraulic lifting mechanism for safe and ergonomic bucket handling. The vacuum pump and water chiller are integrated for streamlined operation. Users should ensure the power plug is ordered separately as it is not included. Proper water pressure for the cooling jacket should be maintained below 40 psi. The PTFE scraping blade requires routine inspection for wear. Optional certifications such as NRTL can be requested if needed.
