Marble, also known as marble, is a recrystallized limestone whose main component is CaCO3. Limestone softens under high temperature and pressure, and recrystallizes into marble when the mineral content changes. There are many colors, usually with obvious patterns, and many mineral particles. The Mohs hardness is between 2.5 and 5. Marble is mainly composed of calcite, limestone, serpentine and dolomite, and its main component is mainly calcium carbonate, accounting for more than 50%. Marble is generally soft in nature, which is relative to granite.
Processing Technology
Marble powder is generally divided into coarse marble powder processing (0-3MM), fine powder processing (20 mesh-400 mesh), and deep processing of marble ultrafine powder (400 mesh-1250 mesh) and micro powder processing (1250 mesh-3250 mesh) ) Four types.
The large pieces of marble are crushed by the crusher to the fineness of the material that can enter the mill (15mm-50mm).
The crushed marble pieces are sent to the silo by the elevator, and then sent to the grinding chamber of the mill by the vibrating feeder for quantitative grinding.
The powdered material is separated by the classifier, the unqualified powder will be returned to the grinding mill chamber for re-milling.
Fine powder complies with the fineness and airflow go through the pipe into the dust collector for separation and collection. The finished powder will be transmitted to bucket elevator by screw conveyor and lifted into Silo for storage by Bucket elevator , then packed uniformly by powder tanker or automatic packing machine.
