Advantages
-
High Drying Efficiency
The entire surface of the material can be used as the effective area for drying, constantly increasing drying strength.
-
Adjustable Rolling Speed
Thanks to the frequency-conversion motor, its rolling speed can be adjusted at the site.
-
High Sealing Performance
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.
-
Wear-Resistant Key Parts
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.
