Calcination of calcium carbonate to produce barite is the traditional production process, with the development of science, the production of barite used mechanized, semi-mechanized shaft kiln and rotary kiln, fluidized bed furnace and other equipment.

Calcination time is correspondingly reduced, lime rotary kiln production only need 2 to 4 hours. Compared with kiln production,it can improve production efficiency more than 5 times. In recent years, the use of ultrafine mill for processing barite improve the utilization value and scope of barite.

The use of barite grinding mill processing flow as follows: the raw barite calcined by calcination equipment such as rotary kiln, the processed lime change into calcium oxide. Then the calcium into the mill’s host through the screw conveyor, under the joint action of the multilayer grinding rings and multiple rollers,it become fine barite powder. Barite powder are transported to storage silos under the action of wind, after removal equipment processing collected, lime will finish processing.
