1. The final moisture content of the material after drying in the dryer is greater than the required value of the specification. The reason is that the material is fed according to the production capacity, and the heat associated with it is insufficient. The method of elimination is to increase the furnace temperature or reduce the feeding amount; 2. The final moisture of the material after drying by the dryer is less than the specified value, which is caused by a large amount of heat supply or a small amount of wet material feeding. The solution is to increase the feed amount of wet materials, but the filling cross-sectional area of ​​the material in the cylinder should not be greater than 20% of the cross-sectional area of ​​the cylinder, so the supply of hot air flow can be reduced, that is, the supply of oil, gas or coal can be reduced.
3. The reason for rotating the cylinder vibration or up and down is that the connection between the roller device and the cylinder should be corrected. The tug is not in the correct position and should be adjusted.
4. The reason why the temperature rise of the bearing of the dryer is too high is: lack of lubricating oil or stolen goods, or adjustment of over-bias, or stuck, it should be dealt with in time.
5, operational safety precautions (1) CGSH sleeve type three-cylinder dryer start and stop should be operated by specialized personnel;
(2) CGSH sleeve type three-cylinder dryer and drag motor should have a good grounding wire;
(3) It is forbidden to overhaul and the person standing under the machine during the start of the machine.
