Coal slime dryer is a kind of rotary dryer, and it is the modified result of rotary dryer. Because the coal slime has the characteristics of high humidity, when drying, coal slime needs to be hit and scattered firstly, and then put the coal slime into the exporting area with high temperature and negative pressure. In the exporting area, the coal slime rapidly evaporates lots of moisture coming across high temperature gas. And then delivery the coal slime into the dryer for drying. This can reduce the length of the dryer and save construction cost for the users.

Here we discuss factors which influence the drying effect of the coal slime dryer.




1. The shoveling plate structure of the Coal slime dryer machine

The coal slim dryer can be equipped with all kinds of shoveling plate, which is used to mix, break, lift and scatter the material after drying, providing more convenience for the contact of wet coal slim and hot air and speeding up the drying.

2. The feeding strength and moisture content of the material

The gasification of water in the drying process occurs on the surface of the particles. Granular materials are easy to scatter and easy to dry. Powder material is easy to form a ball when the material has high moisture content, making the particles covered in the ball with remaining water inside. So the coal slim drying is more difficult than the fine coal drying. In order to speed up the coal slim drying, you could mix the flotation coal concentrate and the fine coal concentrate, or install a special shoveling plate and chain in the cylinder of the coal slim dryer, to break up the coal slim ball.

3. The cylinder angle of Coal slime drying machine

The angle of dryer cylinder influences the handling capacity and determines the nature, granularity and density of the materials. The appropriate angle lies between 4。-5。.
