The high speed of finish rolling requires that there is no torsion in the rolling process. Otherwise, rolling accidents occur frequently in the rolling processing and rolling cannot be carried out at all. Therefore, the high-speed non-twist finish rolling is a basic feature of modern high-speed wire rod mills.

Rod tangling is a problem that should be avoided by using straight rods. rods lt 6 meters are generally never straight. rods should be 152mm shorter than mill length. rod life is maximized of rod length-to-mill diameter is maintained between 1.4 to 1.6. rods wear unequally with thin rod formed at the feed end and forming an elliptical shape.
Rod mill introduction,rod mill working principle. rod mill introduction. rod mills are very similar to ball mills, except they use long rods for grinding media. rod mill is named like this because the grinding media filled in the cylinder are steel rod. the rods grind the material by tumbling within the mill.
