Description
Limestone, known as the "industrial grain" in construction, chemical industry, agriculture and other fields, its powder preparation process directly affects the product quality and application effect. How does vertical mill technology break through the output bottleneck of traditional grinders? Why can a seemingly simple grinding device simultaneously complete multiple functions such as crushing, grading and drying?
Calcium Carbonate Grinding Mill Working principle
the motor drives the grinding plate to rotate through the reducer, the material falls in the center of the grinding plate from the feed port, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, materials move towards the edge of the grinding plate. When passing through the circular groove on the grinding plate, they are crushed by the grinding roller. The crushed materials are carried away at the edge of the grinding plate by the high-speed airflow at the wind ring. Large particles directly fall onto the grinding plate for re grinding. When the materials in the airflow pass through the dynamic and static separators, under the action of the rotating rotor, the coarse powder falls onto the grinding plate for re grinding. The qualified fine powder is grinded together with the airflow, The product is collected in the powder collecting device. Materials containing water are dried in the process of contacting with hot gas to reach the required product moisture.

Re:The data based on Mohs'hardness 3-4 material
Limestone Bond Index≤13kwh/t
Modern vertical mill systems integrate drying (capable of processing raw materials with 15% moisture), grinding, and grading, reducing power consumption by 40% compared to traditional processes. Practices in an 800,000-ton annual glass fiber raw material project show that this system can reduce the comprehensive cost per ton of products by 25 yuan. With the advancement of the "Double Carbon" strategy, vertical mill production lines equipped with waste heat recovery devices have become the preferred solution for upgrading and transforming industries such as cement and metallurgy.
