The Rotary Dryer has large processing capacity, low fuel consumption and low drying cost. The dryer has the characteristics of high temperature resistance and can use high temperature hot air to dry materials quickly. Strong scalability, the design takes into account the production margin, and there is no need to replace the equipment even if the output increases in a small way. The equipment adopts the center-aligning drag wheel structure, and the drag wheel fits well with the roll ring, which greatly reduces the wear and power consumption. The specially designed stop wheel structure greatly reduces the horizontal thrust caused by the tilting work of the equipment. Strong overload resistance, smooth cylinder operation and high reliability.
