As the max input size of the calcium carbonate ultrafine vertical mill is smaller than 30 mm, if the Calcium carbonate rock is bigger than 30 mm, then we will need one small rock crusher to crush the Calcium carbonate into smaller size in advance. If not bigger than 30 mm, then we can directly use the Calcium carbonate ultrafine vertical mill to grind the Calcium carbonate into fine calcium carbonate powder.

On the top of the mainframe of Calcium carbonate ultrafine vertical mill, there is one powder classifier machine which is used to select the Calcium carbonate powder fineness.

If the customer only want to have coarse powder such as around 100 mesh, then we no need to use the powder classifier machine, we can do not open the powder classifier, or even we get rid of the powder classifier machine.
