Roller Extruders

Mitchell Dryers’ roller extruders are supplied to provide a method of producing granules from a filter cake, such as kaolin and pigments. The filter cake is fed from above into the extruder chamber where it is forced through a perforated die plate by rotating rollers to form granules of equal diameter and similar length.

Our roller extruders are predominantly used to enhance the drying process, generating a uniform product particle size which allows more even and efficient drying. They can be mounted above the feed end of a conveyor band dryer or can discharge onto a conveyor for onward processing on other types of dryer or equipment. Our roller extruder comes in a range of sizes to suit the required capacity.

In our Carlisle Test Centre, we have pilot scale roller extruders which are available for development or confirmatory investigations.
