First stage: broken
The bulk material of calcium carbonate is crushed by the crusher to the incoming fineness (15mm-50mm) which can enter the mill.
Second stage: milling
The crushed calcium carbonate small material is sent to the silo through the hoist, and then uniformly and quantitatively fed into the mill grinding chamber through the vibrating feeder for grinding.
Fine powder processing generally uses DBGM vertical mill, MTM trapezium grinding mill; ultrafine powder processing generally uses DBGM ultra-fine vertical mill, YGM raymond mill; sand or coarse powder The processing uses European coarse grinding and straight-through centrifugal grinding.
Phase III: Grading
The ground material is graded by a powder separator, and the unqualified powder is sorted by the classifier and returned to the main machine for re-grinding.
The fourth stage: powder collection
The fine powder conforms to the airflow and enters the dust collector through the pipeline for separation and collection. The collected finished powder is sent to the finished silo through the discharge device through the discharge port, and then uniformly packaged by the powder tanker or the automatic baler.
