The drive of a vertical roller mill – essentially the mill gearbox – has to fulfill two tasks: The first is to reduce the speed of the electric motor to the selected mill speed and to transmit the torque created by the motor. Secondly, the gearbox has to transmit the grinding forces generated by the grinding rollers, from the mill table Get Price

12%We discuss several drive mechanisms for the working stand in periodic cold-rolled pipe mills. This paper focuses on identifying opportunities to increase mill capacity and modernize existing periodic cold-rolled pipe mills. We provide a comparative analysis of a variety of systems for equilibration of the dynamic forces in the working-stand …
The proposed method for monitoring fluctuations of load on the drive mechanism of a rolling mill consists in measuring the output signal of the current transducer of the driving motor within the period of the increase of the load on the working rolls of the mil, measuring the output signal of the low-pass filter, which is connected to the ...
Rolling mill vibration is a worldwide problem, although it has been found that the mill structure defects are the main cause of vibration, but the inhibition measures are difficult to implement. So we discussed the rolling force parameters influence on rolling mill vibration and suppression measures from rolling technology in this article. The results show that the rolling …
Rolling mill screwdown - UNITED ENG FOUNDRY CO. Title: Rolling mill screwdown. United States Patent 2034939.
