Calcite and barite after ultrafine grinding (1250mesh) are two important materials of papermaking industry. Calcite which is also called calcium carbonate has been used as popular filler replacing usual talc and kaolin. Similarly, barite powder is also widely used as filler in papermaking. Equipment Raw material: Calcite and barite
The calcite is used as filler and coating material in most paper-producing industries to harden or smoothen, as necessary. Calcite allows rapid paper drying in the paper-making process due to its oil absorption feature. This makes it a useful ingredient in newspapers, magazines, and high-quality paper-making factories.

In the real world, calcite is a fairly common mineral and one of the most stable forms of calcium carbonate – better known as chalk. It's pretty soft, rating just 3/10 on the Mohs scale of mineral hardness, but it is quite pretty – especially in its impure forms, where it can be grey, red, orange, yellow, green, blue, violet, brown, or even black.
