Zhengzhou Dingli New Energy Technology Co., Ltd., committed to the research of the three-cylinder dryer, three rotary drum dryer is one of the newly developed and unique principle dryer which combined with the working principle between the rotary drum dryer with dip angle and airflow drier . After continuous improvement,it has been reached the international advanced level, not only can deal with low viscosity and high moisture materials but also viscous larger and high moisture materials. It overcomes bulky of the traditional rotary drum dryer and larger cover area of air flow dryer , with small size, high thermal efficiency, light weight, wide applicability, flexible temperature control and so on.
