CHAENG grinding roller sleeve for vertical roller mill is made of wear-resistant alloy steel, and it is fixed on the wheel hub by T-head bolts, butterfly spring and nuts.

Regular and complete maintenance of grinding roller can prolong its service life and also can improve the operation efficiency of vertical roller mill.
Please pay your special attentions on the following points:

1. Ensure that the vertical roller mill is running smoothly (such as checking the height of the material retaining ring, etc.).

2. The retaining ring should retain the proper height and be arranged uniformly.

3. Apply the appropriate pressure to the grinding roller by means of the hydraulic system.

4. Check the effectiveness of the air seal in accordance with the operating instructions for the airtight pipe.

5. When removing the entire grinding roller, the roller must be rolled out of the mill with the rocker arm. And at this time the taper-lock should be loosened.

6. During assembly, ensure the correct position of the opening of the taper-lock connecting roller shaft with the upper rocker. The taper-lock opening should be blocked by ropes to make sure that gas can not get out and dust can not get in.
