The three-cylinder dryer made by our company which is the leading three-cylinder dryer manufacturer and supplier in China is popular among customers for its reasonable three cylinder drying machine price. It is a type of high efficient drying equipment updated from the initial high humidity material dryer.

Three-cylinder dryer

Now, three-cylinder dryer made by our company has reached the international technological level and can handle high humidity materials with both low stickiness and high stickiness. The three-cylinder dryer is used to dry all kinds of slag materials with water content less than 85%. Compared with the traditional single cylinder dryer, it owns a higher thermal efficiency and saves more energy.



Three-cylinder dryer

1. Energy saving: compared with the same specification single cylinder dryer, it increases the thermal efficiency by 40-55%.

2. Small floor space: the three cylinder structure makes it occupy a piece of area as small as 65% of the single cylinder dryer, which reduces the basic investment greatly and makes full use of the land.
