Production scale twin screw extruder with screens are capable of producing 0.5mm to 2.0mm diameter extrudates. The Xtruder can be provided with a cooling option for temperature sensitive material and has a bypass feature that allows for pressure relief.
The wet mix, which is typically prepared in a kneader, pug mixer or high shear granulator (pharma), is metered into the feed hopper by a feeder or hand fed.
Twin screws transport material into the extrusion zone where tapered extrusion blades wipe material through perforated screens creating cylindrical extrudates of a controlled diameter. The extrudates break off by their own weight and are collected for the next processing step.
Features and Benefits
Radial extrudate discharge
Screw transport ensures plug flow operation, first in first out
LCI’s low pressure extrusion systems are extensively used to produce extruded pesticides in the form of Water Dispersible Granules (WDG) and Water Soluble Granules (WSG).
