A suction roll is one of the most important process rolls and also one of the most costly rolls to maintain in a paper machine. By optimizing suction roll maintenance, a paper mill can reduce total maintenance costs, enhance roll reliability, lengthen service intervals and increase the total lifetime of the suction roll.
The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
