Motor Power Laboratory Bead Mill Silicon - Carbon Anode Material Slurry

Silicon-Carbon anode material slurry wet grinding with Boyee agitator Bead mill

Factors influencing the ultimate particle size:

* Formulation of the premix (solids content and viscosity)
* Quality of the premix (particle size distribution and oversize particles)
* The grinding media used (bead size and density)
* Media filling level in the agitator bead mill
* Agitator speed
* Flow rate through the agitator bead mill

Factors that are monitored during operation

* Motor power consumed
* Discharge temperature of the suspension
* Inlet pressure of the suspension to the agitator bead mill
* Cooling water temperature and flow

  Depending on the material to be ground and the objective or end-use of the resulting product, media milling processes may be chosen. In comminution, particles are ground within the slurry by high-pressure shearing and impact forces to break apart the actual particles. In de-agglomeration, the small particles that are joined together are broken apart and separated without changing their primary size or structure. In some cases, both comminution and de-agglomeration are used on a single product.
As mentioned, the size of the grinding media has a direct relationship to the size of the finished product. As a rule of thumb, the final median size will be approximately 1/1000 the media diam. So, to reach a median particle size of 100 nanometers, a grinding media dam of 100 microns is used. Media as small as 30 microns is sometimes used to reach a median particle size less than 30 nanometers.
With very small grinding media, the separation process becomes more critical. In agitator bead mill, the grinding media is retained in the mill by physical interference of a screen or centrifugal force separation system . This is not feasible, or even possible, when using the finest media.
