  • Rolling mills with open-rotating rollers and / or open nip are a safety problem because it can lead to a danger to persons. Taking account of safety aspects, closed systems should preferably be used. However, rolling mills are difficult to complete due to product management. If more than one roll ⁇ transitions necessary, as a result of the generally high viscosity of from Artsvis- can suspensions incurred a lot of manual work. By GE ⁇ listen to the removal of the dispersed product from the flow sheet, the emptying of the mill, to the changing of the product ⁇ container. Automation is only possible to a limited extent.
  • agitator ball mills are closed systems, they require more effort. So the grinding media must be separated and it is important to ensure that a clogging Fung of separation devices or discharge openings is avoided by grinding media and / or product oversize. In the event of a product change, it may also be necessary to remove the grinding media from the process area to completely clean the machine. This means a longer downtime.
  • Planetary roller extruders are also known from the state of the art. These are used predominantly for the production of plastics, in which case several solid or liquid product components can be added to the extruder, compacted, mixed, plasticized, dispersed and chemically converted.
  • the verar ⁇ beitete mass is continuously pressed under pressure through a nozzle, or outlet opening. For this purpose, a pressure of up to about 100 bar can be produced in the extruder. The greatest pressure is in the process zone towards the product outlet, or at the product outlet itself.

  • the housing and the spindles are arranged vertically during normal operation.
  • a planetary roller mixer with a product outlet arranged above the product inlet in a simple manner results in a vertically arranged planetary roller mixer, in which the housing and the spindles are vertically aligned during operation when the planetary roller mixer in the lower is rich fillable and the suspension is discharged in the upper area.
