The stirred mills are much more efficient for fine grinding and regrinding than conventional tumbling mills. Conventional mills require long retention time and tremendous energy input for micron size production. This work aims at studying the parameters affecting wet ultrafine grinding of Egyptian talc from Shalatin locality of

The installation of vertical mill. In a vertical mill, drying, grinding, and separating/classifying of ground material are done simultaneously. The hot air used for drying is supplied with a hot wind generator. Slag contains iron grain, which could damage the rotating table and aggravate grinding efficiency.

4. Grinding process. In the ball mill, the material is mainly crushed by impact and friction. In the vertical grinding mill, the material is mainly extrusion, and grinding is the auxiliary. The residence time of the material in the vertical mill is 23 minutes, while in the ball mill it takes 1520 minutes.

Talc (Mg 3 Si 4 O 10 (OH) 2) is a phyllosilicate mineral with a T‒O‒T layer composed of tetrahedral silicon and octahedral magnesium, which share oxygen and are strongly bonded with each weak van der Waals bonds between the T‒O‒T layers is the origin of softness of talc. The silicon in the siloxane sheet renders talc hydrophobic, since it cannot easily be substituted with ...

Activation of talc by grinding in a planetary mill followed by treatment with 2 M NaOH was employed as means for basicity enhancement. Such protocol enabled profound modification of talc structure, otherwise resistant to treatment with a basic solution. Deep changes, not addressed in the literature reports so far, took place in the course of ...

This manuscript aimed to examine the impact of operating parameters on the wet grinding of talc in a verticaltype stirred media mill. Within the scope of the research, the effects of operating parameters including media filling ratio, solid mass fraction, grinding media size, and grinding time were studied. The findings were assessed based on the product particle size (d50, d10), surface area ...
