The present study examined the effects of dry grinding, using ball-milling, on the structure of reference well-crystallized (KGa-1) and poorly crystallized (KGa-2) kaolinite powders from Georgia. Grinding produced a strong structural alteration, mainly along the c axis, resulting in disorder and total degradation of the crystal structure of the ...

Dry grinding mills are well-suited to metal powder requirements such as homogeneity of the mixture, uniformity of the morphology and relatively narrow particle size distribution. Milling offers a number of advantages over atomization, the other major production method for metal powder. These advantages include:

The preparation of powder is nothing more than grinding to disperse the fineness. There are two types of wet grinding and dry grinding. The representative of dry grinding is the ball mill. In wet grinding, bead mills are the most popular. First of all, we need to know what dry grinding and wet grinding have in common. Features of Dry Grinding
