These four principles should be followed when using the laboratory air classifier

Laboratory air classifier is a small processing equipment. In addition to its small output, its classification accuracy is the same as large and medium-sized air classifier, and its stability is better. It is often used in university laboratories, scientific research institutions, small processing enterprises, etc., and is recognized and favored by many users

When the laboratory air classifier is working, the materials to be crushed are fed into the machine from the feed hopper at the side of the housing, and the grinding roller device suspended on the plum blossom frame of the main machine rotates around the vertical axis. At the same time, the grinding roller rotates itself. Due to the centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring, so that the blade lifts the materials to the grinding roller and the grinding ring, The material is crushed due to the rolling compaction of the grinding roller. The air separation process of the laboratory air classifier is that after the material is ground, the fan blows the air into the main machine shell to blow up the powder, which is sorted by the analyzer placed above the grinding room. The fine and coarse materials fall into the grinding room for regrinding. The fine and coarse materials that meet the specifications enter the cyclone collector with the wind flow, and are collected and discharged through the powder outlet, which is the finished product. The air flow returns to the fan from the return air pipe at the upper end of the large cyclone collector. The air path is circular and flows under negative pressure. The increased air flow of the circulation air path is discharged through the exhaust pipe between the fan and the host, and enters the small cyclone collector for purification. 1. In order to make the laboratory air flow classifier normal, the equipment should be developed; Safety Operation System for Equipment Maintenance” In order to ensure the long-term safe operation of the superfine mill, necessary maintenance tools, lubricating grease and corresponding accessories are required. 2. When the grinding roll device of the crusher has been used for more than 500 hours and the grinding roll is replaced again, each rolling bearing in the roll sleeve must be cleaned, and the damaged parts should be replaced in time. The oil filling tool can be a manual oil pump and a grease gun. 3. During the use of the laboratory air flow classifier, there should be fixed personnel to take care of it, and the operators must have a certain technical level. The operators must receive necessary technical training before the installation of the ultra-fine mill, so that they can understand the principle and performance of the ultra-fine mill and be familiar with the operating procedures. 4. After using the superfine air flow classifier for a period of time, it should be overhauled, and the wearing parts such as grinding roll, grinding ring, blade, etc. should be overhauled and replaced. Before and after using the grinding roll device, the connecting bolts and nuts should be carefully checked to see whether there is looseness and whether the lubricating grease is sufficient. The above are the four principles to be followed when using the laboratory air classifier. In order to ensure the service life and safe operation of the equipment, users need to pay great attention.
