Limestone powder is widely used in electric power, metallurgy, cement, chemical industry, building materials, coatings, papermaking, rubber, medicine, food, and other fields, and has broad market prospects.
The process flow of the limestone grinding production line mainly includes the following steps:
1. Crushing: The initial step is to run large chunks of limestone through a crusher, reducing them to a size suitable for grinding. Generally, it is appropriate to control the grinding particle size within 2 cm.
2. Grinding: The crushed limestone small pieces are lifted to the silo and then sent to the mill evenly and quantitatively through the vibrating feeder for grinding. The mill can use different types of equipment, such as an ultra-fine grinding mill, which uses an advanced grinding roller and ring design to achieve higher production capacity than traditional mills with the same fineness and power of the finished product.
3. Grading: The ground limestone powder is graded and screened through a powder separator to ensure that every particle of powder meets the specified standards. The unqualified powder will be returned for re-grinding.
4. Collect: The sorted qualified materials enter the pulse dust collector or cyclone collector to achieve material and gas separation. The collected materials are sent to the next process through the discharge valve, and most of the airflow participates in the next cycle. The excess airflow is cleaned by pulse dust removal and then discharged to the atmosphere.
