The patented Twin Dome Granulator (TDG) Extruder offers high capacity twin screw extrusion through a hemi-spherical die that allows for uniform extrusion pressure and shear.
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 the wet mix to the extrusion zone where it is then wiped through a dome die (screen) to produce well formed, cylindrical extrudates of a controlled diameter. The extrudates break off by their own weight and are collected for the next processing step.
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).
LCI's low pressure extrusion systems in conjunction with our spheronization systems are used to produce high API drug pellets.
