A production plant for processing a suspension and a method for dispersing suspensions. The production plant comprises an extractor or a planetary roller mixer (1), a conveying device and a metering device. The planetary roller mixer (1) comprises at least one central spindle (2) with a toothing (3), at least one planetary spindle (4) with a toothing (5) and a housing (6) with an inner toothing (7) or a housing comprising at least one bushing (8) with an inner toothing (7). The planetary roller mixer (1) further comprises at least one product inlet (9) and at least one product outlet (10). During normal operation, the product outlet (10) is above the product inlet (9) and/or comprises an overflow (14) in the product discharge line (13) provided at the product outlet (10) so that the processing zone of the planetary roller mixer (1) can be substantially completely filled with the suspension.

A planetary roller extruder with planetary spindles and stop ring. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. 1.72(b). As stated in 37 C.F.R. 1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading Abstract of the Disclosure. The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

Mixing systems that include a mixer housing and a plurality of roller assemblies for mixing and processing materials is disclosed. Each roller assembly includes a roller that extends between sidewalls in the mixer housing and rotates to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. Each of the rollers may have a protrusion geometry formed in the outer contact surface, where each protrusion geometry is complementary to an adjacent roller.
