Calcium carbonate is a common inorganic compound, commonly known as limestone, limestone, limestone, etc. it exists in aragonite, calcite, chalk, limestone, marble, limestone and other rocks. According to different production methods, calcium carbonate can be divided into heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate and crystal calcium carbonate. Heavy calcium carbonate (GCC) is made by grinding natural limestone and calcite directly by mechanical method (such as Raymond Mill). Light calcium carbonate is prepared by calcining limestone at high temperature, water digestion, carbon dioxide carbonization, dehydration, drying and grinding.

Grinding process of calcium carbonate:
Stage one: fragmentation
The bulk material of calcium carbonate is crushed by the crusher to the feed fineness (15mm-50mm) that can enter the pulverizer.
The second stage: grinding
After crushing, small pieces of calcium carbonate are sent to the silo by the elevator, and then they are evenly and quantitatively sent to the grinding chamber of the mill for grinding by the vibration feeder.
LM vertical mill, MTW European mill and 5x European Intelligent mill are generally used for fine powder processing; lum ultra-fine vertical mill and MW ring roller micro mill are generally used for ultra-fine powder processing; cm European coarse grinding and straight through centrifugal mill are selected for sand making or coarse powder processing.
Stage three: grading
The grinding material is graded by the separator, and the unqualified powder is returned to the host machine for regrinding after being graded by the separator.
The fourth stage: collecting powder
The powder meeting the fineness will flow through the pipeline into the dust collector for separation and collection. The collected finished powder will be sent to the finished product bin by the conveying device through the discharge port, and then packaged by powder loading tanker or automatic packing machine.
