Four steps to effective pigment dispersions: starting from ...

Pigments are a key component in a coating formulation and proper selection and dispersion is critical in determining the performance of the coating. In a recent study regarding the requests for technical assistance received over the past 2 years, it was noted that nearly 80% of the formulation issues were resolved by modifying or changing the ...

Maximize pigment dispersion efficiency during pre-mixing

Final grind: Dv90 18 microns. The PreMax eliminated the milling step and reduced overall production time from an all-day 6-8 hours to less than 1 hour in a single tank without cooling and without the extensive clean-up required with the media mill, three dispersers, tanks, pumps and piping. The PreMax also exceeded the previous grind spec.

process runs cleaner, wet edges are gone, and the mill has seen a decrease in sheet breaks. Quality has also improved due to factors such as a reduction in streaks from applicator roll ribbing. One negative factor observed is that jet split losses, where the coating jet splits into a "V" due to debris in the nozzle, were higher recently.

Ball Mills - an overview | ScienceDirect Topics

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
