Problems needing attention in the use of ultra fine vertical mill

Date of release:2018-01-31 Author: Click:

The superfine vertical mill is a grinding machine for fine powder and ultrafine powder. It is mainly applicable to non flammable and explosive nonmetallic materials with medium and low hardness, low humidity less than 6% and less than 9 moth hardness, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talcum, mica, magnesite, and barite. Gypsum, alunite, graphite, fluorite, phosphate rock, potassium ore, pumice and so on.

Recently, the market reflects the popularity of the ultrafine rayon grinding machine, and the small editor has given a description of the problems that should be paid attention to in the process of using the superfine Raymond mill.

In the first superfine grinding process, a fixed person should be responsible for the management. The operator must have a certain technical level. Before the ultra-fine grinding is installed, the operator must be trained in technology to make the operator understand the principle performance of the superfine grinding and be familiar with the operating rules. In order to make superfine grinding work normally, the "safety operation system for maintenance and maintenance of superfine grinding" should be formulated to ensure the long-term safe operation of ultrafine grinding, and necessary maintenance tools and lubricating grease accessories.

Secondly, air volume control: the air volume control valve located on the intake pipe of the fan is opened to the maximum position and adjusted according to the fineness and output requirement. The regulating valve located on the dust outlet pipe of the fan outlet is transferred to the feed inlet without dust ejection, and the air volume is small and the fineness is high. However, it should be noted that if the air volume is too small, it is easy to adjust the material in the air duct below the main engine.

Finally, the fineness adjustment: according to the size of the material, the soft and hard, the water content, the specific gravity are different, the processing is also different, and the above analysis machine is adjusted, the speed is high, the fineness is high, the speed is low, and the fineness is low. If the fineness is increased, the output will be reduced correspondingly. If the demand is not met, the speed of the fan should be adjusted, so that the users can grasp it flexibly. The scrapping limit of grinding roller ring should not be less than 10mm. When the machine stops, the feed is stopped and the main engine continues to run. The residual material continues to be grind. For about one minute, the mainframe motor and the machine motor can be closed, the grinding work is stopped and the motor of the fan is stopped to purge the residual powder.
