Trouble shooting of mill operation by analysing the torque distribution between the rollers* [Full subscriber]

Abstract Individual electrohydraulic drives allow constant measuring of the torque in each roller during milling operations. The automation of each mill operation and of the whole tandem allows working with the optimum torque in each mill, giving the maximum extraction. During optimum four-roller mill operation, the top roller takes the same portion of the torque related to the inferior rollers and additionally the input torque, if the fourth roller is moved by the top roller. The torques in each roller should be kept uniform but, in case of any mechanical problems inside the mill, the total torque or the torque…
