Hi! Glad you can click and enter our website!
Rotary dryer is mainly composed of rotating body, lifting plate, transmission device, supporting device and sealing ring. It is generally suitable for granular materials, and can also be used for semi-dry viscous paste materials or partially mixed materials, and materials with higher water content. Rotary dryer has the advantages of wide application range, convenient operation and high operation rate. It is widely used in the cement industry to dry raw materials such as clay, slag, gravel, and coal...Learn More
