Calcite is a common calcium carbonate mineral with a wide distribution. Its finished products can be used to make rubber, plastics, paints, coatings, food additives, high-quality putty powder, etc. according to different processing requirements, which are quite popular in grinding industry.
So if user wants to invest in processing calcite, which grinding mill should they choose?
1.Production process for calcite grinding
First, large pieces of calcite need to be crushed by a crusher to a proper size that can enter the grinding equipment. Then, the material was grinded into powder under the act of grinding mill. The qualified calcite powder will be classified by separator along with the air flow, while unqualified calcite powder is returned to the grinding cavity of mill for re-grinding. The calcite powder that meets the fineness requirements will enter the powder collection system through the pipeline with the airflow, and be packaged in a unified manner.
2.Equipment configuration for calcite grinding
As we all know, calcite grinding plant will be processed through 4 different stages: crushing, grinding, classifying and collecting. So the equipment configuration for calcite grinding includes:
⑴ C6X Jaw Crusher
C6X Jaw Crusher has the characteristics of large feed range, high operating strength, and strong durability, which is suitable for processing primary in crushing hard stone like calcite. Its wear-resistant parts are made of high-quality material, which not only can improve crushing efficiency, but also extend the service life of equipment and reduces the maintenance cost.
⑵ SCM Ultrafine Grinding Mill
SCM grinding mill integrates various functions including grinding, classifying and collecting.
Multi-head cage powder separator: It can effectively improve the precision of powder selection. The fineness of calcite powder can be adjusted arbitrarily between 325 and 2500 mesh according to the needs of users.
Pulse dust collector, silencer and anechoic room, which can make grinding process free of dust pollution, low environmental noise, and meet national environmental protection production requirements.
The picture below shows a calcite grinding project in China. The project adopts SBM’s SCM1000 ultrafine mill. The finished powder is used to make S95 grade steel slag powder, which can be used as steel slag powder, slag powder, high-strength phosphor slag powder, composite mineral powder and cement. Due to the high cost-effective investment of this grinding project and the good quality of the finished products, SBM is widely praised by the customers and downstream manufacturers.
