Description

Revolutionize your limestone processing operations with our state - of - the - art Limestone Vertical Roller Mill.

Engineered with cutting - edge technology, this mill is the ultimate solution for achieving unparalleled grinding

efficiency, ensuring your production process reaches new heights of productivity.

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.

Technical Data

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.
