Feldspar is one of the most important raw materials in the ceramic and glass industries. Known for its fluxing ability, feldspar lowers the melting temperature of mixtures, promotes better vitrification, and improves strength and transparency in finished products. Whether used in ceramic tiles, sanitaryware, tableware, or in glass containers and fiberglass, feldspar must be processed to exact fineness and purity standards.

Consistent particle size distribution (typically 20–150 μm) and low levels of impurities such as iron are critical for product quality. Traditional grinding equipment often struggles to achieve these requirements, resulting in high wear, excess power consumption, and inconsistent output. To overcome these challenges, Liming Heavy Industry offers the MTW European Grinding Mill—a high-performance solution specifically designed for feldspar processing.
