Advanced ultra-fine vertical grinding equipment designed for large-scale dry powder processing of non-metallic minerals including calcite, limestone, marble, talc, barite, dolomite, and heavy calcium.

The electric motor drives the grinding disc through a reducer. Material enters through the feeding port and moves toward the disc edge via centrifugal force, where grinding rollers crush it. High-speed airflow carries crushed material upward, with coarse particles returning for regrinding. The dynamic separator ensures only fine powder is collected as final product, while hot gases simultaneously dry materials to required moisture levels.
