一种适用于粉体的风冷螺旋下料管
By designing an air-cooled spiral feeding pipe, the contact area and time are increased by utilizing a spiral V-shaped sandwich slide. Combined with air blowing by a fan and vibration by a vibrating motor, the problem of low cooling efficiency of powder materials is solved, and efficient powder cooling is achieved.
