A paper machine parts roller

The production of roller is mainly composed of rollers, initial school static balance, axle head overgain assembly welding, fine car and fine school dynamic balance. If the tolerances such as roundness, cylindricity and straightness are below 0.2mm, the grinding machine of cylindrical grinder or roll grinding machine is required after the fine car. If the surface hardness is required, the heat treatment process needs to be increased.

After the roll forming, for anti-rust anti-corrosion, wear-resistant and the need of support, also need to surface treatment or coating, such as painting, galvanized, TEFLON coating, rubber coating, chrome plating, ceramic coating and oxidation process.

According to the size of classification, there is a large such as papermaking machinery with roller (length can reach more than 10 meters, more than 1500 mm in diameter), small, such as automatic assembly line of belt conveyor with pinto roller (generally within 1 meter length, diameter is 159 mm)
