Relying on the rich local limestone resources in Inner Mongolia, the project processes desulfurization stone powder and supplies it to local power plants for use as desulfurization stone powder.
Processing material: limestone
Feed particle size: <30mm
Finished particle size: 325 mesh 93%
Finished water content: <1%
Capacity: 35 tons/hour
Equipment composition: a VRM1900 vertical mill (500kw), feeder, elevator, raw material bin, screw feeder, vertical mill, dust collector, fan and control cabinet, etc.
When the limestone vertical mill is running, the limestone is first crushed and then stored in the gravel bin. After the constant speed regulation of the electronic belt scale, a certain amount of limestone will be poured out, and then transferred to the interior of the limestone vertical mill through the rotary impeller. . The continuous movement of the grinding rollers and grinding discs will squeeze and grind the limestone with great force, and finally grind it into powder. After powder selection, the unqualified coarse powder particles will be shot down on the grinding disc to continue grinding, and the qualified powder will be brought out along with the airflow to become the product.
When the limestone vertical mill is working, the internal hot blast stove will generally generate hot air. According to different production conditions, a fuel-fired hot blast stove or a coal-fired hot blast stove can be selected, so that the water in the raw materials can be continuously evaporated. Ensure that the moisture content of the finished product produced by the limestone vertical mill is below the specified range. In order to improve the production efficiency of the limestone vertical mill, the system can also be transformed, and the slag can be installed and adjusted so that it can return, so that the production efficiency can be improved.
