Xingnong asks you, do you know the three-step method to improve the sealing of the ball mill grinding head?

Ball mills are becoming more and more dominant in mineral processing equipment, and problems may also occur during use. The following is a brief introduction to the method of improving the sealing of the grinding head
Improving the sealing method of the grinding head is divided into three steps
First, add a length of spiral barrel to the outer end of the feed spiral barrel. The spiral blades are welded on site. The extension section is connected to the mill together with the original spiral barrel with screws.
Second, add a spiral barrel to the outer end of the extension section. Felt positioning ring, industrial felt is installed in half, one side is coated with butter, the ring is connected to the extended spiral barrel with countersunk head screws
Third, a friction sealing ring is set at the outer end of the felt, which is inserted into the feed material On the bucket, two stop bars are made and welded on site to prevent them from rotating. A number of springs are used to hold the back. The spring seat and the feed bucket are welded together so that the end face of the retaining ring is always close to the felt and is not affected by the felt part. Effects of wear and tear. There should be a gap between the sealing back-up ring and the outer diameter of the feed hopper cylinder. This gap should be blocked with cotton dipped in butter. A pressure plate is added to the back-up ring. The pressure plate is tightened with the sealing back-up ring with screws. When installing the feed hopper, pay attention to the installation position to move back and allow the length of the extension spiral barrel.
