In Vietnam feldspar black grinding mills are vital for producing fine powder used in paint and ceramic applications. A mill with a 3 tph capacity and an output fineness of 60 microns processes black feldspar from Nghe An. The fine powder is crucial for enhancing the quality of ceramic tiles and pigments. Vietnamese manufacturers rely on these mills to produce consistent high-quality feldspar powder for both local and export markets meeting demands for fine texture and strength in finished products.
