Message: | The three return dryer is to shorten the size of the dryer body by changing the single cylinder body of the single barrel dryer into the three cylinders that are overlapped together in order to shorten the size of the dryer body. When the machine is working, the material and the hot air flow enter the inner and outer cylinder in turn, after the Z-shape reciprocating flow of the body, the material is dried and then unloaded by fully utilizing the heat energy. url:http://www.zhongbomachine.com |
