Use And Maintenance Of Limestone Ultrafine Mill

How to better use and maintain the limestone ultrafine mill

We introduce modern scientific management technology, cooperate closely with many colleges and universities and scientific research institutions, manufacture with precision, and keep pace with the times. After years of research, we have designed and developed a large number of crushing and milling equipment with advanced technology. We have a strong micro-powder grinding machine design and development, manufacturing, installation and commissioning, technical maintenance, irregular return visits, strict quality assurance and quick after-sales service, each link has been carefully arranged to solve a series of customers Worried about it.

Use And Maintenance Of Limestone Ultrafine Mill

Limestone is a commonly used material. The processed limestone is widely used. Our company has developed a professional limestone fine powder mill equipment, which specializes in processing and grinding limestone materials. The following is a comprehensive summary of the use of the limestone micronized mill equipment and how to maintain it to better extend the life. Generally, the maintenance of the main machine of the ultrafine mill is the most important. In the main machine, the grinding roller assembly is suspended on the roller hanger through the cross-arm shaft. The roller hanger is fixedly connected with the spindle and the blade holder, and the pressure spring is pressed. On the outer end surface of the cantilever bearing chamber, the cross roller shaft is used as a fulcrum to force the grinding roller to press tightly on the inner circular surface of the grinding ring.

When the motor drives the main shaft to rotate through the transmission device, the blade mounted on the blade holder and the blade The grinding roller rotates synchronously, and the grinding roller rotates around its own axis while rolling inside the grinding ring. The motor drives the impeller of the analyzer through the transmission. The higher the impeller speed, the finer the sorted powder. In the grinding chamber, due to the certain water content in the material to be ground, the water and gas are evaporated due to the production and heat during grinding, and the connection of the pipes of the whole machine is not tight, so that the outside air is sucked in, so that the air volume of the circulating airflow is increased, so as to ensure that the ultrafine mill is negative. Working under pressure, the increased air flow is discharged into the bag filter through the residual air pipe between the fan and the main unit, and is purified and discharged into the atmosphere.

Moreover, such mistakes are easily generated during the use of the ultrafine mill, for example, the mill does not produce powder or produces less powder. The finished powder of the ultrafine mill is too thick or too fine. The current of the mill main machine rises, the machine temperature rises, and the fan current decreases. The mill main machine is noisy and has a large vibration. The mill fan is vibrating. Grinding machine grinding roller device into the powder bearing damage cup and so on.

So how can we better avoid these mistakes? Below we have a detailed summary for you, in order to make the mill powder machine normal, we should develop a safe operation system for equipment and equipment to ensure the long-term safe operation of the mill. At the same time, necessary maintenance tools as well as grease and corresponding accessories are required. When the grinding roller device of the ultrafine mill is used for more than 500 hours to replace the grinding roller, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time. The fueling tool can be manually pumped and greased. During the use of the mill, there should be a fixed person responsible for the care, the operator must have a certain level of technology. Before the installation of the ultrafine mill, the operator must carry out the necessary technical training to understand the principle performance of the ultrafine mill and familiar with the operating procedures. After the grinding machine is used for a period of time, it should be repaired. At the same time, the wearing parts such as the grinding roller and the blade should be repaired and replaced. The grinding roller device should be carefully checked before and after use to see if there is any looseness. Whether the grease is added.
