Abstract: A spraying head for a granulating installation includes a slotted nozzle in which a nozzle channel having an oblong cross-section of flow is limited downwards by a floor surface, upwards by a top surface and laterally by a side face on each side. An oblong flow control body in the nozzle channel extends axially between the two side faces to limit the height of a nozzle slot. The control body is pivoted about a longitudinal axis to adjust the height of the nozzle slot. The control body is a cylindrical body having an oval cross-section and a central axis which is approximately centrically disposed between the floor surface and the top surface and pivoted about its central axis, such that underneath as well as below the control body a nozzle slot is formed, the height of which can be adjusted by pivoting the control body about its central axis.

Abstract: A drainage tank for granular material/liquid mixture includes a low part and a high part provided with a lid. A device for separating the liquid and the granular material is arranged in the low part. A device for evacuating excess liquid is arranged in the high part and includes a number of overflow sleeves passing through the lid. The overflow sleeves have, above the lid, an overflow edge that is adjustable in height.
