Advantages

70 t/h rotary drum dryer

The entire surface of the material can be used as the effective area for drying, constantly increasing drying strength.

Thanks to the frequency-conversion motor, its rolling speed can be adjusted at the site.

It is equipped with the dust removing device and LX combined lifting plate to avoid the phenomenon that the cylinder is filled with hot air.

The reasonable structural design of the roller and various lubrication methods help the roller avoid being worn or having broken shaft. The cylinder is made of steel to enhance its hardness and toughness.

Customer feedback

Gwendolyn

The slag dryer features excellent production, stable performance, advanced technology and low energy consumption with reasonable design, consisting of a rotary cylinder, the air-inducing equipment and high-speed dispersing equipment. Small space as it takes up, it earns lots of benefits for us.

Kristin

The sawdust dryer from FTM can be continuously added to the drying pipe by a screw conveyor. In the transportation and dispersion of the high-speed hot gas stream, the water is evaporated to obtain powdery or granular finished products, conforming to our requirements for the dryer.
