Rotary Drum Drier

1.Rotary Drum Drier suit for minerals,metallurgy,calcuim
2.operate reliable,easy to maintain,large production
3.simple design
drier is a cylinder,its main body is a litte bit slantwise,and the rotate speed can be adjusted within bounds.Wet raw materials are sent into cylinder, the materials are well-distributed and dispersed after be turned over by shovelling plate,then the materials contact with the hot air fully,the drying is accerlated.Shovelling plate can be selected to meet different materials

This dryer is particularly suitable for drying big granules in chemicalindustry,minerals,metallurgy industry,and so on.It can also dry special powder and granule material,such as lightweight calcium carbonate,floridin,magnetic particle,graphite,and dregs of a decoction ,the drying temerature should be low, and the raw material should be dried continuously in large scale
