Calcium carbonate powder is widely used in various industries,and  calcium carbonate is very common in our life,such as the main component of marble,calcite and limestone  are calcium carbonate.Here we will introduce the process of calcium carbonate from stone to powder. 

1.Crushing of heavy calcium carbonate raw materials (calcite, marble, limestone)
Large pieces of calcite, marble, and limestone are transported by special vehicles to the raw material warehouse. The forklift/manually delivers the material to the jaw crusher for crushing and crushing to less than the calcium carbonate grinding mill machine feed size (15-30 mm).

2.calcite, marble, limestone feedstock
The calcite, marble and limestone crushed by the crusher are lifted by the hoist to the storage hopper, and the storage hopper is discharged and fed to the main machine evenly by the feeder.

3.Grinding mill for grinding
After the calcite, marble and limestone enter the calcium carbonate grinding mill machine, the products that have passed the grinding are screened by the screening system and then enter the collector by the pipeline. The collected calcite, marble and limestone fine powder are discharged through the discharge valve, which is the finished product. The powder falls into the calcium carbonate grinding mill machine and is regrind.

4.Finished product collection

The calcite, marble, and limestone powder are connected to the pulse dust collector through the ventilation pipe connected to the mill. The produced heavy calcium carbonate powder enters the powder collector and waits for packaging. The airflow purified by pulse dust collection flows into the blower through the residual air duct above the dust collector, and the air path is circulated. Except that the blower is positive pressure to the grinding chamber, the airflow in the other pipelines flows under negative pressure, and the indoor sanitary condition better.
