Four principles should be followed when the airflow mill works

When the air pulverizer works, the material to be crushed is added to the machine from the hopper on the side of the machine shell, relying on the grinding roller device hanging on the host plum frame, revolving around the vertical axis, and at the same time its own rotation, due to the action of centrifugal force during rotation, the grinding roller swings outward, pressing on the grinding ring, so that the shovel knife shovels the material to the grinding roller and the grinding ring. Because of the rolling roller to achieve the purpose of crushing the material. Air selection process: after grinding the material, the fan blows the wind into the main casing, blowing the powder, sorted by the analyzer placed above the grinding room, the fine and coarse material falls into the grinding room and regrinding, the fineness meets the specifications with the air flow into the cyclone collector, and the collection is discharged through the powder outlet, which is the finished product. The air flow is returned to the fan by the air return pipe at the upper end of the large cyclone collector. The air path is circular and flows under negative pressure. The increased air volume of the circulating air path is discharged through the exhaust pipe between the fan and the main engine, and enters the small cyclone collector for purification treatment.
1. In order to make the ultrafine mill normal, the equipment "equipment maintenance and safe operation system" should be formulated to ensure the long-term safe operation of the ultrafine mill, and the necessary maintenance tools and grease and corresponding accessories should be necessary.
2. When the use time of the roller device of the airflow mill exceeds about 500 hours and the roller is replaced, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time. The refueling tools can be used with manual oil pump and butter gun.
3. During the use of the airflow crusher, there should be fixed personnel responsible for the care, and the operator must have a certain technical level. Before the installation of the ultrafine mill, the operator must carry out the necessary technical training to understand the principle and performance of the ultrafine mill and be familiar with the operating rules.
4. After the use of the air flow mill for a period of time, it should be overhauled, and the wearing parts such as the grinding roller, grinding ring, and shovel knife should be overhauled and replaced. The connecting bolts and nuts of the grinding roller device should be carefully checked before and after the use to see whether there is loosening and whether the lubricating grease is added.
