Slag grinding vertical roller mill is a mechanical equipment specially used to grind slag materials into fine powder. Slag usually refers to solid waste generated during the smelting process, such as blast furnace slag, converter slag, etc. These slags can be used as building materials, cement admixtures, etc. after appropriate treatment.
The working principle of the slag vertical roller mill is to drive the reducer through the electric motor, thereby driving the grinding disc to rotate. The slag material is evenly fed into the center of the grinding plate through the feeding device. Under the action of centrifugal force, the material moves toward the edge of the grinding plate. At the edge of the grinding disc, the material is strongly squeezed and ground by the grinding roller, thereby being crushed and finely ground.
The crushed materials are picked up by the high-speed airflow at the edge of the grinding disc and enter the upper separator. In the separator, the coarse-grained materials fall back to the grinding disc due to gravity for re-grinding, while the fine-grained materials are taken out of the mill along with the airflow and become the final product after being collected by the dust collection device.
Vertical roller mills for slag grinding have many advantages, including compact structure, small footprint, stable and reliable operation, low energy consumption, high grinding efficiency, and good product quality. In addition, since the slag material is strongly squeezed and ground inside the mill, the active ingredients in it can be fully released, improving the performance and use effect of the product.
Slag grinding vertical roller mill is an important slag processing equipment, which is of great significance for improving the comprehensive utilization value of slag resources and protecting the environment.
