water content ball mill wet grinding

The influence of the slurry density on thefine wet grindingperformances of abatch ball millwas examined for analumina hydrate feed. Irrespective of the operating conditions, the size reduction process proceeds fast in the first period of grinding (20 min); then its rate progressively reduces and after 1–2 h the size of the product approches a final asymptotic value.

On the analysis of fine wet grinding in a batch ball mill

After 15 min ofgrinding, the most dilute slurries (67% and 80%water) appear almost confined in the zone of themillfilled by theball charge(see Fig. 1(c) and (d)). By decreasing thewater contentto 50%, a layer of slurry starts adhering to the wall and at the same time theballsbecome partially covered by the suspension (see Fig. 1(b)).

Wet grinding of CaCO3 with a stirred media mill: Influence

Wet grindingwithvertical stirred ball millsis typically carried out for slurries containing particles smaller than 200 μm, such as industrial minerals and pigments. Filtration is an important unit operation, which is performed in order to reduce thewater contentof the slurry aftergrindingand concentration, and prior to drying and transportation. Pressure filters are used to obtain the maximum dryness of the product.

The characteristics and enzyme digestibility of corn stover vary depending onwaterinput duringballmilling. The dry milling mode (0%waterinput) leads to quickgrindingand, subsequently, a high glucose yield. Among the samples milled at 100 °C, the corn stover milled with 400% (w/w)watershowed the highest glucose yield.
