Plagioclase feldspars (Na or Ca): NaAlSi 3 O 8 CaAl 2 Si 2 O 8 (albite and anorthite) Alcalic feldspars (K or Na): K/NaAlSi 3 O 8 (albite and all Kfeldspars) Complete solid solution (miscibility) only occurs in the plagioclase group, between albite and anorthite. Albite and Kfeldspars mix only at high temperatures.
The Kfeldspar concentrate was also milled in a pilotscale HiCOM 15 nutating mill. The mill products were characterised with respect to their size distributions, specific surface areas and their relative degree of structural disordering as calculated from Xray diffraction analysis.

ultrafine (1 micron) grinding (Becker, 1987; Ma, Hu, Zhang, and Pan, 1998; Reed, 1995; Szegvari, 1994; Szegvari and Yang, 1989). These mills use a shaft with pins or discs to stir the grinding media. In addition to wet and dry grinding, the stirred ball mills can be used vertical or horizontal oriented.
Feldspar grinding mill is an industrial ultrafine powder mill, it can grind feldspar into a fine powder ( mesh). There are 2 types of feldspar grinding mill: HGM ultrafine grinding mill and CLUM vertical mill. What is feldspar? Feldspar is the general term for minerals in the feldspar group.
