Vertical Roller Mill for Limestone Grinding - High Efficiency & Low Energy Consumption

Description

Against the backdrop of the continuous pursuit of high efficiency, energy conservation, and environmental protection in industrial production, limestone vertical mills, as an advanced grinding equipment, are playing an increasingly important role. With the booming development of the economy, commercial concrete has taken a key position in the field of engineering construction and is constantly moving towards high-performance, green and environmentally friendly directions. Limestone powder, as an important mineral admixture for concrete, has a significant impact on the quality and performance of concrete. Research and practice have shown that when the fineness of limestone powder reaches 325 mesh, it can greatly improve the workability and workability of concrete, effectively reduce slump loss, improve mechanical properties, increase slump while avoiding bleeding. Especially in high-strength concrete, it can also reduce cohesion and enhance fluidity. ​
At the same time, with increasingly strict requirements for environmental protection worldwide, newly built coal-fired power plants with sulfur content greater than 1% must be equipped with desulfurization facilities. At present, limestone and lime gypsum wet process are the most widely used desulfurization technologies in power plants, accounting for about 86% of the total capacity. The fineness requirement for limestone powder in this process is usually above 90% for 325 mesh or above 95% for 250 mesh. In order to meet the high-quality and large-scale demand for limestone powder in the market, we have successfully developed a high-performance limestone vertical mill through extensive technological innovation and improvement.

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.
