Ultrafine Mill Installation And Maintenance

Precautions for installation and maintenance of ore ultrafine mill

Ore mill is widely used in the grinding of mineral materials in metallurgy, building materials, chemical industry, mining and other fields. It is suitable for processing various non-flammable and explosive minerals with Mohs hardness below 7 and humidity below 6%. Gypsum, talc, calcite, limestone, marble, potash feldspar, barite, dolomite, granite, kaolin, bentonite, medical stone, bauxite, iron oxide red, iron ore, etc., fineness of the finished product is 613 microns~ Between 440 micrometers (0.613 mm - 0.44 mm), the combination of the analyzer and the fan can meet the requirements of different users.

After the ultrafine mill crushes the large raw material to the required feed size, the material is transported to the storage bin by the bucket elevator, and then the electromagnetic vibrating feeder is evenly sent to the grinding chamber of the main machine to enter The material of the grinding chamber is ground between the grinding roller and the grinding ring, and the powder after grinding is brought to the analysis ultrafine mill by the fan airflow, and the fine powder that meets the fineness requirement enters the large cyclone collector through the pipeline, and is separated and collected. And then discharged through the unloader is the finished product. The blade system plays a very important role in the operation of the mill mainframe. The utility model is located at the lower end of the grinding roller, and the material is shoveled and fed into the roller ring between the blade and the grinding roller to form a pad layer, and the material layer is rotated by the grinding roller to generate an outward pressing force to the material. Milling, thereby achieving the purpose of milling.

The operation procedure and use method of the mill are very simple and easy to understand, but the installation and maintenance are also a lot of attention. The first choice is that the mill should be properly kept when it is installed. The exposed surface should be coated with anti-rust grease and avoid Sun and rain, in order to prevent the body from rusting into the water, to establish a maintenance system. The plant and foundation shall be of sufficient height and installation position according to the size of the installation base diagram of the ultrafine mill. The foundation of the mill shall be of high standard cement and shall be embedded with steel and can be poured into the pipeline or cable trench. It should be equipped with 2~3 tons lifting tools for the installation and maintenance of the grinding machine.

The ore fine powder mill equipment should also pay attention to many matters in the use. The humidity of the material is preferred, that is, when the moisture contained in the material is large, the material is easy to adhere in the mill, and it is easy to be blocked during the feeding process. Raymond's milling ability is reduced. The fineness and fineness of the material after grinding by the mill are high, that is, the finer the material milled out by the ultrafine mill, the smaller the mill mill output. The composition of the material, the more fine powder contained in the material before the mill, the more the mill is affected, because these fine powders tend to adhere and affect the transport. For the content of fine powder, it should be sieved once in advance. The viscosity of the material. That is, the greater the viscosity of the material, the easier it is to adhere. The better the wear resistance of the grinding parts of the mill, the greater the capacity of the mill. If it is not wear-resistant, it will affect the capacity of the mill.

If the mill is from the factory to the use time of more than 6 months, the main shaft system, transmission, grinding device, and analytical oil pool should be cleaned and inspected. After the cleaning inspection, sufficient lubricating oil should be added to each component.
