Medium speed coal mill introduction
The medium speed coal mill is a machine that crushes and grinds coal into coal powder. It is an important auxiliary equipment for the coal powder furnace. Coal mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal dressings, and glass ceramics. The medium-speed coal mill has displacement and gap-adjusting technology. The high-humidity material is not easy to block.
With the rotation of the millstone, the material moves to the edge of the millstone under the action of centrifugal force. When passing through the annular groove on the millstone, it is crushed by the grinding roller, and the crushed material is brought up by the high-speed airflow of the wind ring at the edge of the millstone. The particles fall directly onto the millstone and re-grind. When the material in the airflow passes through the upper separator, under the action of the rotating rotor, the coarse powder falls to the millstone to be re-grinded, and the qualified fine powder is ground together with the airflow.
Check the lubrication condition of the bearing chamber before and after the main engine, such as grease deposits, to be cleaned, to update the grease, to see the bearing wear condition, to see if it needs to be replaced. Maintenance is a work that must be done every day, so that there will be no big problems in the future. Maintenance work should be carried out frequently. After shutdown, check whether the bolts of the machinery are loose. The loosening must be strong.
