In 2023, the Omani bentonite market decreased by -28.6% to $5.9M for the first time since 2020, thus ending a two-year rising trend. Over the period under review, the total consumption indicated a slight increase from 2012 to 2023: its value increased at an average annual rate of +1.0% over the last eleven years. The trend pattern, however, …
The diameter of the grinding disk is 200 mm and the one of the classifier is 100 mm. Both parts rotate with a variable speed of up to 11,000 rpm. After the particles are fed to the grinding zone of the mill, they are stressed by the rotating grinding pins and then transported by the main air flow to the impeller wheel classifier.

The grinding experiments were conducted in the absence of bentonite and the results showed that the values for P 80 were 25 μm (40% solids), 29 μm (55% solids), 37 μm (62% solids) and 39 μm (70% solids). The grinding experiments were also conducted in the presence of bentonite by changing three factors: solid percentage, …
