Rubber mixing mill with stock blender is chiefly used for the mastication, mixing, warming up and sheeting of rubber, especially as accessory of internal mixers to make rubber sheets. The rollers are made of chilled cast iron with vanadium and titanium alloys. The roller face is hard and anti-wear. The internal cavity is processed to make temperature well proportioned on the roll surface. The machine is equipped with an overload protection device to prevent the major components from being damaged due to overloading. The machine is also equipped with an emergency device. When an emergency accident happens, just draw the pull rod, and the machine will stop immediately. It is safe and reliable. The transmission system adopts a hard facing gear reducer, which has a compacted structure with higher transmission effciency, lower noise and longer service life. The base frame is a complete framework, which is convenient for installation. NOTE: all the models may be optionally equipped with either copper bushes or rolling bearings.
