How to solve the problem of large differential pressure of vertical slag mill? At this time, you should reduce the supply of materials, or even shut down the machine, and then check the possible causes. Generally, there may be the following reasons:
1. Reduce the supply of materials to see if the pressure will improve.
2. Check whether the negative pressure entering the mill is too small, and properly open the air valve to increase the ventilation volume, so that the materials can be timely carried out by the air to avoid accumulation in the mill.
3. The grinding temperature of materials will become higher and the vibration will become greater; This may be due to the poor grindability of the material, so the use of water spray can be appropriately increased and the pressure of the grinding roller can be increased.
4. The bearing is overheated, the bearing is short of oil or dust, and the bearing is damaged. Properly let the grinder rest for a while, check and clean the bearing, add oil to the bearing, and replace the bearing in time to avoid damaging other parts.
5. The grinding cavity sounds abnormally, and the roller makes a collision sound on the grinding ring; After stopping the machine, open the grinding chamber, and turn the machine manually. It is found that some rollers are rotating but not rotating, and the rollers and grinding rings are broken. It is analyzed that it is caused by poor lubrication of roller bearings.
6. No separation or little flour, low output. The powder locker is not adjusted properly and the sealing is not tight, resulting in powder backdraft, large wear of the blade, inability to shovel materials, blocked air duct, and poor sealing of pipe leakage.
Of course, there are many reasons for the excessive differential pressure of the vertical slag mill. Here are just some of the reasons.
