Double drum dryer heated mainly by the inner drum and the central tube. Hot air into the cylinder, from the material outlet end flaps such as sand dryer after the outer cylinder, is discharged from the raw material supply side. Material is moved along the annular space of the housing wall and the central inner cylinder. The heat required for drying, a portion of the hot air through the inner wall surface of the heat transfer tube, a heat conductive manner to pass the material; the other part by hot air countercurrent contact with the material in the annular space of the housing wall and the center of the inner cylinder in order to convective heat The way to pass the material. The advantage of this structure is that: the first hot air through the inner tube, the entrained dust can settle, while reducing the heat loss to the surrounding environment, to improve the effective utilization of heat. With the rapid economic development of large sand dryer, green energy has become the current social development and promote a major theme of sand dryer price, whether it is business or personal in the pursuit of profit maximization, the pursuit of efficiency of new sand dryer reduce energy consumption, which has become our common consciousness. High efficiency, low energy consumption and drying equipment to become the best production needs of enterprise development.巩义鑫 Lee Heavy dryer during the study design, the use of the actual production process solutions into the device to achieve optimal rational allocation, the solid line integration, complete and perfect the production line, so that you use the least energy to create the greatest value dryer sand production line |.
