Cement Clinker Grinding Mill
The cement clinker uses limestone, clay, and iron as the main raw materials, and is prepared into a raw material at an appropriate ratio, and is partially or completely melted and cooled to obtain a semi-finished product. In the cement industry, the most commonly used is portland cement clinker. The main minerals are composed of tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium iron aluminate.
The first stage: Crushing
Large pieces of cement clinker are crushed by the crusher to the feed fineness (15mm-50mm) that can enter the mill.
The second stage: Milling
The crushed small pieces of cement clinker are sent to the silo by the elevator, and then sent to the grinding chamber of the Vertical roller grinding mill for uniform and quantitative grinding by the vibrating feeder.
The third stage: Grading
The powdered material is classified by the classifier, and the unqualified powder is classified by the classifier and returned to the host for re-milling.
The fourth stage: Collecting
Fine powder complies with the fineness with airflow go through the pipe into the dust collector for separation and collection. The finished powder collected by the delivery device is delivered to the finished product bin, and then packed uniformly with the powder tanker or automatic packing machine.
