1. Equipment structure: GGBS vertical roller mill is mainly composed of the main machine, power part, transmission part, grinding roller part, pressure arm frame, tensioning device, spray lubrication system, pneumatic system, and electronic control system. These parts work together to complete the grinding work of slag.

 

2. Working principle: During the working process, the motor drives the grinding disc to rotate through the reducer. The material (i.e., blast furnace slag) falls into the center of the grinding plate from the feed port through the air-locked feeder, and at the same time, hot air enters the mill from the air inlet. As the grinding plate rotates, the material moves toward the edge of the grinding plate under the action of centrifugal force. When passing through the annular groove on the grinding plate, it is crushed by the grinding roller and crushed. The crushed materials are picked up by the high-speed airflow of the wind ring at the edge of the grinding disc, and the large particles fall directly onto the grinding disc for re-grinding. When the materials in the air flow pass through the upper separator, under the action of the rotating rotor, the coarse powder falls from the cone hopper to the grinding disc and is ground again. The qualified fine powder comes out of the grinding along with the airflow and is collected by the dust collection device, which is the product.

 

3. Performance characteristics: GGBS vertical roller mill has the advantages of high efficiency, energy saving, and environmental protection. Its grinding efficiency is high and can meet the needs of mass production; at the same time, due to the use of advanced lubrication and pneumatic systems, the wear and failure rate of the equipment is low, and the maintenance cost is low. In addition, the equipment generates less noise and dust pollution during the grinding process and meets environmental protection requirements.

 

4. Application fields: GGBS vertical roller mill is widely used in slag treatment fields in steel, cement, electric power, and other industries. By grinding blast furnace slag into a fine powder and mixing it into concrete, the strength, durability, and impermeability of concrete can be improved, production costs can be reduced and environmental pollution can be reduced.

 

In summary, the granular blast furnace slag vertical roller mill (GGBS) is an efficient and advanced grinding equipment with broad application prospects in the field of slag treatment.
