Abstract: A method for obtaining gypsum using a flue-gas desulfurization system (FGD) having a gypsum suspension, which includes fine materials such as active carbon particles or residual carbonate particles for example, accumulates in the scrubber of a wet flue gas scrubber. The gypsum-containing suspension is thickened by at least one hydrocyclone, and the thickened gypsum suspension is discharged via the underflow of the hydrocyclone. Water is fed to the hydrocyclone in addition to the gypsum suspension via a dedicated feed line such that the content of fine material is thus reduced with respect to the suspension volume in the underflow.

Abstract: The rolling bearing comprises an inner ring 1, an outer ring 2, at least one row of rolling elements and at least one seal 7 provided between the outer and inner rings. The seal 7 has, in cross section, the overall shape of an H and comprises internal lips 21, 22 and external lips 23, 24 forming the two substantially parallel branches of the H. The inner and outer rings 1, 2 comprise opposite radial ribs 25, 26 located axially between the internal and external lips 21 to 24 to axially retain the seal.

Abstract: A rolling-element bearing includes a first bearing ring (2) and a second bearing ring (4) opposing the first bearing (2) in a radial direction (3). A sealing element (6) of the rolling-element bearing includes a radially-encircling seal support (8) extending in the radial direction (3) by a predetermined distance towards the second bearing ring (4). The seal support (8) is interference-fit and removably attached to an axial end side (9) of the first bearing ring (2). A sealing lip (10) is attached to the seal support (8) and extends from an end of the seal support (8) opposite the first bearing ring (2) in the radial direction (3) up to a mating surface (12), which is part of the second bearing ring (2).
