Grinder Roller is a common equipment problem during its operation. Once this problem occurs, the wear between the roller core (grinding roller) and the lining plate will be aggravated, and the hot air and cement particles will continue to scour the mating surface, resulting in grooves. The generation of grooves causes impact and collision between the roller core (grinding roller) and the lining plate, and in severe cases, the lining plate is cracked or even broken, and the machine is damaged, especially the damage of the reducer, resulting in malignant events.
Once the wear problem of the vertical grinding roller core (grinding roller) occurs, the general maintenance method is difficult to solve. The editor recommends using the Sole carbon nano-polymer material technology for maintenance. Why is this?
The material is an epoxy two-component composite material composed of metal powder, ceramic powder, etc., which can be well adhered to various metals, concrete, glass, plastic, rubber and other materials, and has good wear resistance. Serves wear and rebuilding of metal components.
And the maintenance process is also relatively simple: surface grinding and absolute ethanol cleaning of the worn parts of the vertical grinding roller core (grinding roller) → clean the roller sleeve with the inclined surface and wipe SD7000 mold release agent for use → adjust the material in proportion to uniform No chromatic aberration→Apply the blended material evenly to the part to be repaired→Material curing→Reinstall the roller sleeve.
In order to serve enterprise users more conveniently and efficiently, we innovatively use Internet technology to create a “Sole database” of equipment problems and solutions that users are concerned about, and use AR intelligent technology to guide users to implement rapid maintenance. Provide users with scientific and reasonable solutions and operating specifications in a short period of time.
Reasons and solutions for common problems of Grinder Roller. The grinding roller of vertical mill is not only an important component of vertical mill equipment, but also a type of large-scale steel castings. If it is not dealt with in time, the consequences will be very serious. So what happens when the grinding roller is running and how to solve it?
Instantaneous temperature difference
The temperature inside and outside the grinding roller rises or falls sharply, causing the roller sleeve to expand or shrink rapidly. Excessive thermal stress causes the grinding roller to crack. When the material density and wear are uneven, it is more likely to cause multiple roller sleeves to burst at the same time. The above situation The main reason is that the wind temperature at the entrance and exit of the mill is adjusted too fast before and after the vertical mill is started or stopped, or the on-site personnel are eager to enter the mill.
Foreign matter entered into the mill
If the metal material with higher hardness enters the mill or the parts in the mill fall off, the grinding roller may be damaged after being crushed by force. If these foreign objects are not discharged in time, but are stuck on the inner ring or base of the retaining ring, and cannot be removed in time, the mill will have periodic abnormal vibration during the later operation, which will not only damage the vertical mill, but also have certain dangers Therefore, foreign objects must be cleaned up in time when the mill is overhauled.
