XK-450 rubber open roll mill

1. The rolls of the machine are made of chilled cast iron of vanadium and titanium alloy. So the surface ishard and wearable; the internal processing can make the temperature of the roll surfacewell-proportioned.

2. The machine equipped with overload protection devices and emergency brakingdevice. The transmission system adopts either hard tooth flank dual axis reducer or NGE hard toothflank planet reducer, which has compact structure low noise and high efficiency.

3. The base of the machine is a complete frame, so it’s very convenient for installation.
