Abstract: The invention relates to a method for monitoring the bending of a shaft, particularly a shaft in a mixing kneader, the shaft having a bearing at least on one side. In a first step, the deviation of the shaft from the radial position is measured on at least one position different from the bearing of the shaft. In a further step, a reference value is optionally determined from the measured deviation from the radial position. In a third step, the deviation from the radial position as measured in the first step or the reference value found in the second step is compared with a predetermined limit value.

Abstract: Mixing kneader comprises at least two shafts (2, 3) that bear kneading bars (5) on crosspieces (4), can rotate in bearings at both ends, are driven from at least one end and are surrounded by a housing (6) that has top openings (10) above the shafts and a product discharge opening (11). The mixing kneader has at least one of four defined features, e.g. the natural bending frequencies of the shafts differ from the excitation frequencies by at least 5%. Mixing kneader comprises at least two shafts (2, 3) that bear kneading bars (5) on crosspieces (4), can rotate in bearings at both ends, are driven from at least one end and are surrounded by a housing (6) that has top openings (10) above the shafts and a product discharge opening (11). The mixing kneader has at least one of the following features: the natural bending frequencies of the shafts differ from the excitation frequencies by at least 5%; at least one shaft is a hollow shaft through which a temperature-controlling medium flows from an inlet (12) to an outlet (13); at least one top opening is closed by a displacer and the gap between the displacer and the kneading bars is no greater than that between the kneading bars and the housing; the cross-section of the product discharge opening is adjustable. An independent claim is also included for a process for producing poly(meth)acrylates using a mixing kneader as above.
