Calcium carbonate product is a powder, according to the average particle size of calcium carbonate powder (d) size, calcium carbonate can be divided into fine calcium carbonate (d> 5μm), micro-powder calcium carbonate (1μm)

The ambient air filtered by the primary and middle efficiency is sucked into the hot air by the induced draft fan of the drying system, and the hot air generated after heat exchange with steam enters the flash drying main engine, and the drying process of heat and mass transfer is completed in the drying main engine with the filter cake to be dried through the spiral feeder. The gas-solid mixture is separated by the cyclone separator and the cloth bag dust collector. The material is separated from the gas in the drying system, discharged from the drying system, and the tail gas is discharged into the atmosphere by the induced draft fan.

The drying chamber is equipped with grading ring and swirl sheet, the fineness and final moisture of the material can be adjusted, and the final moisture of the calcium carbonate can be adjusted to ≤0, 1%.
