MSK-SFM-14 Heavy-Duty Benchtop Lab Roller Mill with Optional Single or Dual Airtight 2L Stainless Steel Milling Jars, Adjustable Speed up to 567 rpm
MSK-SFM-14 is designed to address the challenge of efficiently reducing particle size in metallic, non-metallic, and organic powders within laboratory settings. This benchtop roller mill offers flexibility by accommodating either a single or dual milling jar configuration, allowing users to tailor the milling process to their sample throughput and experimental needs. It is particularly suited for tasks requiring fine grinding, dispersing, and crushing of powders down to sub-100 micron sizes.
The milling action is achieved by planetary balls inside airtight 2-liter stainless steel jars, which generate intense centrifugal forces to grind and shear materials effectively. The operator can customize milling speed up to 567 rpm (single jar) or 525 rpm (dual jars), and select continuous or pulse milling modes with adjustable time control up to 99 hours. The roller spacing and jar dimensions are adjustable to accommodate milling tanks ranging from approximately 135 to 320 mm in length and 105 to 300 mm in diameter, depending on safety cover status.

Typical Applications
This roller mill is ideal for laboratories requiring precise size reduction of powders for research, quality control, and product development in fields such as materials science, chemistry, pharmaceuticals, and metallurgy. It handles metallic and non-metallic powders as well as organic materials, enabling fine grinding and homogenization.
Configuration & Operating Notes
- Standard package includes stainless steel milling balls and 2L stainless steel jars (one or two depending on model)
- Optional vacuum, pressure, and liquid nitrogen cold grinding jars are available for specialized milling conditions
- Adjust roller spacing to fit milling jars within specified size ranges; safety lock sensors deactivate when covers are open
- Consider pairing with ultrasonic filtration systems for post-milling particle separation
