Vertical roller mills are known for their high - efficiency grinding and large - capacity processing. The calcium carbonate is fed onto a rotating grinding table, and the grinding rollers, which are pressed against the table by hydraulic pressure, rotate and crush the material. The air flow system in the vertical roller mill is also important.
It helps to transport the ground powder and separate the fine and coarse particles through a classifier. The classifier can be adjusted to control the fineness of the output powder, ensuring that it meets the required standards.

Applications of Ground Calcium Carbonate
In the plastic industry, it is used as a filler. Adding ground calcium carbonate to plastics can increase the hardness, stiffness, and dimensional stability of plastic products. For example, in the production of plastic pipes, the addition of calcium carbonate can make the pipes more resistant to deformation and have better heat - resistance. It can also reduce the production cost of plastics as calcium carbonate is relatively inexpensive compared to some other raw materials.
In the rubber industry, ground calcium carbonate is used to improve the performance of rubber products. It can enhance the tensile strength, tear resistance, and abrasion resistance of rubber. In the manufacturing of tires, for instance, the addition of calcium carbonate can improve the durability and safety of the tires.
