What is a three-cylinder dryer for drying what is a three-cylinder dryer for drying?
What is a three-cylinder dryer, a simple point is that industrial use is used to dry materials, such as some coal mines, sand and other items, a cylindrical machine used for industrial drying materials, but this dryer is The modified three-cylinder dryer is a multi-cylinder dryer transformed on the basis of a single-cylinder rotary dryer. Although the two types of dryers are both modified dryers, but The three-cylinder dryer is better to use. The three-cylinder dryer prolongs the time of the material of the original dryer in the dryer, and relatively speaking, the three-cylinder dryer can ensure the humidity of the material in the dryer. and tightness.

So how does this three-cylinder dryer work? First, the materials that need to be dried are provided to the dryer from the feeding device, and the materials enter the dryer to contact the heating device, and then rotate and heat. This process seems to use a frying pan to stir fry continuously. It can be well understood that this process is to put sand, coal mines and other items directly into the dryer for stirring and heating, until all the materials are dried after heating. However, this process is much more complicated than frying melon seeds, not only to find the internal stir fry, but also to repeatedly stir fry in the middle layer.
What are the characteristics of this three-cylinder dryer? Generally, this kind of three-cylinder dryer is dried with imported materials, and about one-sixth of all the invested equipment is made of this material, and the materials required for drying materials must be less than 0.5% to be considered qualified. , and this kind of dryer guarantees that its thermal efficiency can reach 70% to be considered a qualified three-cylinder dryer, and such a dryer is more energy-saving and environmentally friendly.
