间接传热式转筒干燥机是对物料进行干燥作业的常用设备,由于该设备运转可靠,操作弹性大,处理能力高,属传导干燥型,在轻质碳酸钙生产中使用较多。传统转筒干燥机(以下简称干燥机)的传动多采用渐开线齿轮、齿圈边缘单传动结构,齿圈采用挠性固定结构,在温度较高的工作环境中,虽然 Indirect heat transfer drum dryer is drying equipment for materials commonly used equipment, due to the operation of reliable equipment, flexible operation, high processing capacity, is a conductive dry type, used in the production of light calcium carbonate more. The traditional drum dryer (hereinafter referred to as the dryer) and more use of involute gear, gear ring edge single drive structure, gear ring with flexible fixed structure, in the high temperature work environment, though
