Vietnamese feldspar black grinding mills play a key role in producing fine powder for ceramics and paints. A mill with a capacity of 15 tph and a particle size output of 80 microns is ideal for processing black feldspar from Ha Giang. The powder is used in tile manufacturing and paint pigments where it provides durability and color consistency. The reliable performance of these mills helps Vietnamese companies meet demand for high-quality feldspar powder in domestic and export markets.
