When the air flow pulverizer works, the materials to be crushed are fed into the machine from the feed hopper on the side of the hood. Relying on the grinding roller device suspended on the plum blossom frame of the main engine, it rotates around the vertical axis and rotates itself at the same time. Due to the centrifugal force during rotation, the grinding roller swings outward and presses tightly against the grinding ring, so that the shovel blade scoops up the materials and sends them between the grinding roller and the grinding ring, The purpose of crushing materials is achieved due to the rolling and rolling of the grinding roller. Air separation process: after grinding the materials, 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 chamber. The fine and coarse materials fall into the grinding chamber for regrinding. The materials with qualified fineness flow into the cyclone collector with the wind, and are discharged through the powder outlet after collection, 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 circulating and flows under negative pressure. The increased air volume of the circulating air path is discharged through the waste gas pipe between the fan and the main engine and enters the small cyclone collector for purification treatment.
1. In order to ensure the normal operation of the ultra-fine pulverizer, the equipment "equipment maintenance and safe operation system" shall be formulated to ensure the long-term safe operation of the ultra-fine pulverizer. At the same time, necessary maintenance tools, grease and corresponding accessories shall be provided.
2. When the roller grinding device of the air flow pulverizer is used for more than 500 hours, each rolling bearing in the roller sleeve must be cleaned, and the damaged parts shall be replaced in time. The refueling tools can be manual refueling pump and grease gun.
3. Fixed personnel shall be responsible for the care of the air mill during use, and the operator must have a certain technical level. Before the installation of the superfine pulverizer, the operators must receive necessary technical training to understand the principle and performance of the superfine pulverizer and be familiar with the operating procedures.
4. After the air mill is used for a period of time, it shall be overhauled, and vulnerable parts such as grinding roller, grinding ring and blade shall be overhauled and replaced. The connecting bolts and nuts of the grinding roller device shall be carefully checked before and after use to see whether there is looseness and whether the lubricating grease is sufficient.
