1. Regular inspection and maintenance of coal sludge dryer: regular inspection and maintenance can ensure that all parts of the dryer are in good working condition. Including cleaning the dryer, replacing wearing parts, checking the transmission system to apply lubricant and so on. Regular maintenance can also reduce failures and downtime, and improve production efficiency.

2. Control the feed rate and moisture content of coal slurry: the feed rate and moisture content of coal slurry directly affect the stability of the dryer. If the feeding speed is too fast or the moisture content is too high, it will lead to uneven drying or incomplete drying. Therefore, it is necessary to control the feeding speed and moisture content of coal slurry to ensure that its treatment in the dryer is uniform.

3. Control the hot air temperature and hot air speed: hot air temperature and hot air speed are the key factors affecting the drying effect of coal slurry. It is necessary to adjust the hot air temperature and hot air speed according to the nature and moisture content of the coal slurry to ensure that the coal slurry can be evenly dried under the appropriate temperature and wind speed.

4. Strictly abide by the operating procedures: when operating the coal slurry dryer, you need to strictly abide by the operating procedures, including the correct operation of the equipment, the use of the correct amount of coal slurry feed and control the hot air temperature and hot air speed. Only in the case of strict compliance with the operating procedures, to ensure the stability and safety of the coal slurry dryer.
