Banbury Fill Factors
Banbury Fill Factors
(OP)
I would appreciate some info concerning the effects of usng too high of a fill-factor in mixing and dispersion.
The literature suggests average fill-factors (by volume) at about 0.75 - we seem to be running a lot higher than that; up to 0.9
How does this affect dispersion of blacks, heat, mixing efficiency etc.
Thanks

RE: Banbury Fill Factors
Another factor is the type of throat the mixer has. If there's a deep throat, a larger batch loading can probably be used.
If you have the luxury to do so, you could run several batches with different loading factors and see where the optimum is. It may be different for different compounds, especially if there's a big difference in filler and plasticizer levels.
