May 15, 2005 4. Conclusions. The presence of self excited parametric vertical vibrations of the working rolls causes important dimensional defects of the strip thickness δ m.The analytical solutions confirm in agreement with the results of earlier studies,, that such vibrations take place when the respective natural frequency of the strip (usually the fourth one) is approximately equal

Feb 01, 2021 In addition to ball mills, one of the other common mills in factories is the vertical roller mills (VRMs). In contrast to grinding by ball mills that need other devices to dry and separate powder, VRM performs separation, grinding, and drying processes just in one machine and reduce the number of devices in a close circuit.
