Experimental Study on Superfine Grind Process for the Preparation of Calcium Carbonate Particles via Vibrated Mill

To obtain the minimum particle size calcium carbonate, the vibrated mill was used to grind analytically pure calcium carbonate. This experimental method was introduced to research what effect grinding time, grinding media size and filling rate have on grinding in order to select the optimal operation condition. The results showed that the vibrated mill could grind analytically pure calcium carbonate with size of about 1.5 μm, and with the grinding time increased, the size of the particles decreased. However, its size remained even reversed when decreased to a certain degree. The optimum technological condition is a parameter combination including 10 mm diameter grinding ball, 65% filling rate and 500 g powder quality.
