Grinding mill is a kind of grinding equipment used earlier in China, which is mainly used for grinding and processing of materials in mining, metallurgy, chemical industry, building materials and other industries. So, what should be paid attention to during the operation of the mill? The following Henan Liming Heavy Industry for the user to explain in detail the notes of the mill in the operation process:

First, because the mill is with the help of grinding rollers, grinding ring and grinding material between the impact, friction and make the material crushed, so the machine running vibration and noise are larger, but the sound is uniform, there should not be abnormal ringing, if you find abnormal sound or host current suddenly rises and a long time to come down, then you should immediately shut down the machine to check.

Second, the feed size should be uniform, fast and slow should be appropriate, too slow will reduce the output, too fast will be blocked air ducts, the machine can not work, and even cause accidents. Feed speed can be adjusted according to the host motor current rise and fall.

Third, into the host grinding material should be block, such as powder or block in the seepage of more powder, it will reduce the output of the mill.

Fourth, the classifier motor for the use of variable frequency speed control motor, adjust its controller variable frequency knob, you can get a different classifier speed, the higher the speed of the finished product finer particle size.

Fifth, often check the bearings, temperature rise over 80 ℃ or abnormal noise should be stopped to check.

Sixth, the newly installed unit should first do experimental test run to check the accuracy and reliability of the installation, empty test run should not be more than two minutes, shut down to check the flexibility of the rotation of each piece of machinery, there is no overheating phenomenon, whether the bolts are loose, the host vibration is not too large, adjusted to add material after the trial run, and then shut down to check the above items after an hour, if there is no problem can be transferred to normal production.
