The raw materials of the pulverizer for grinding the pulverized coal and coal slurry must not be mixed with stones, metals and other foreign materials, so as not to damage the
vertical roller mill. The grinding of stones, pebbles, construction waste and beer bottles should use the special mill of Huapu.
When the vertical roller mill is running, the operator shall not disassemble the vertical roller mill during operation to observe the working conditions in the grinding room, and the maintenance tools shall not be placed on the vertical roller mill or stuffing.
The operator shall not wear gloves, and it is strictly prohibited to put his hand into the stuffing box in case of blockage. When delivering materials, he shall stand on the side of the grinder to prevent the sundries from hurting his face.
Do not stop immediately after the end of the work, but idle for 2-3 minutes so that the materials in the vertical roller mill can be completely discharged. After the stop, cleaning and maintenance should be carried out.
The hammer head is the main vulnerable part. After wear and tear, the hammer head should be replaced at the same time regardless of the same direction or Angle. When replacing the new hammer head, the whole set of hammer head should be replaced at the same time. The bottom of the sieve is also vulnerable to damage. If part of the bottom of the sieve is damaged, it can be riveted and repaired.
