Calcite is one of a non-metallic minerals, the calcite is white and delicate, with good plasticity and fire resistance and other physical and chemical properties. And the calcite powder also can be widely used in paint, paper, rubber and other industries, playing a great role.

Under the drive of the motor, the grinding disc of the super fine grinding mill turns. At the same time the wind goes into the ultra fine grinding mill from the intake, dolomite is feeding onto the center of the disc. Under the action of centrifugal force, the material moves evenly from the center to the edge of the grinding disc. When passing through the grinding roller on the roller area, material is grind by roller, when large pieces of material directly crushed, and fine material after squeezed forms material bed for inter granular smash.

At this time, the crushed material continues to move to the edge of the disc until it is taken away by the strong air flow at the wind ring, while the larger particles of stone lumpswill fall back to the mill plate to continue to be crushed. When the material in the airflow passes through the upper separator, the coarse particles are returned to the grinding disc under the action of the rotor blades. Qualified fine powder is discharged together with the air, and collected by the collector of the system. The powder, which is collected, is finished product of calcite grinding mill.
