Ultrafine heavy calcium carbonate is an industrial mineral product made by grinding and processing natural calcium carbonate. It is mainly used in industries such as rigid plastics, synthetic leather, recycled rubber, sealing strips, coatings, feed, toothpaste, rubber and plastic products to change properties, reinforce, fill, increase calcium content, and reduce costs.

The quality of the grinding balls used during the grinding and pulverizing stage of ultrafine heavy calcium carbonate plays a very important role in the quality of the material product. Nowadays, alumina grinding balls are one of the most commonly used grinding materials. Generally, for ultrafine calcium carbonate with a particle size of 2000-6000 mesh, tower mills, vertical mills, or stirred mills are mainly used for wet grinding, and the diameter of the balls used is between 1.5-2.5mm (other sizes are not excluded and depend on the specific situation).

Of course, non-metallic ore primary crushing may also use large balls with a diameter of φ30-60mm. Currently, companies commonly use balls with a specific gravity between 2.7-4.2, and 2.7g/cm is one of the materials with high customer demand as homogeneous grinding balls.

As a grinding material, alumina grinding balls can greatly improve grinding efficiency, reduce grinding time, save energy, and reduce costs. At the same time, it effectively increases the effective capacity of the ball mill, thereby increasing the amount of material added for grinding.
