Product Options

Milling Jars:
MSK-SFM-15 is a planetary ball mill with independent speed controls of revolution and self-rotation to achieve a flexible speed ratio and different impact and shear effects for different kinds of materials and particle sizes. 


  • Independent speed control for revolution (10 - 400 RPM) and self-rotation (50 -1600 RPM)
  • Touch screen control panel for programmable milling recipes. 
  • Four 500 mL stainless steel jars are included


  • 208 - 240V AC,1p, 50/60 Hz
  • 3500 W
  • 10-ft power cord without a power plug. 

Milling Speed and centrifugal acceleration

  • Main revolution: 10 - 400 RPM;          Centrifugal acceleration:  <16 g 
  • Self-rotation:      50 - 1600 RPM;        Centrifugal acceleration:  <120g
  • Total Centrifugal acceleration:  <136 g
  • Recommended speed ratio: 1 - 3
  • Maximum milling allowance for the wet mill (Total weight of samples and milling media):
    • <2000 g @ revolution < 350 rpm
    • <1000 g @ revolution < 400 rpm
    • The total load for the dry mill is half of the wet mill. 

Touch Screen Control

  • Programmable milling process including milling time and milling speed. 
  • 10 recipes
  • 8 segments of speed control per recipe

Recommended Material Size

  • Intake size:   < 3 mm for most materials;
                         < 10 mm for brittle materials
  • Output:         < 1um average @ wet mill;
                         < 20um @ dry mill
Note: The output granularity is dependent on the material physical properties such as size, milling media, and processing time. Minimum granularity can be as small as 0.1 um according to the customer's feedback.

   Application Notes

  • SS304 mixing jar is suitable for grinding various metal materials.
  • To avoid contamination,  please pre-milling the material 2-3 times before normally milling, which can make a coating on the surface of the jar and balls.   Please use one jar for one type of material.
  • For milling the oxide material, please choose alumina/Nylon jars and zirconia media. DO NOT USE stainless steel balls in Alumina jars. 
  • Must place 4 jars or 2 in symmetrical with similar weights in the ball mill to keep balance during rotation, If using one jar, you must put another jar with the same weight in a symmetrical position.  Otherwise, unbalance rotation, especially one jar, may damage the machine.
  • Please click underline to learn Centrifugal Force calculation.
