Two rolls: one is chrome-plated roll or artificial stone roll, the other is special rubber for sizing, the top roll is fixed, the side of the rubber roll is pressurized, the pressure is pneumatic, and the hyperbolic pneumatic tire device is adopted. The maximum linear pressure does not exceed 400KN/M.
The sizing temperature,wear resistant and corrosion resistant materials ,and the strength and toughness can withstand the impact of filler,and the adhesive surface has good surface properties.
