material balancing in rotary dryer

Aug 05, 2014 Aug 05, 2014 However, most rotary dryer operators usually meet with the phenomenon of uneven feeding, even material blocking when feeding the materials, which not only decreases the drying efficiency, but also affects the quality of the dried materials. Only by balancing the material feeding of the rotary dryer well, can we make the dryer machine
