LCI - Model TDG -Twin Dome Granulator Extruder
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.
- Low pressure extrusion with negligible heat generation
- Screw transport ensures plug flow, first in first out
- Easy-to-clean clamshell design extrusion chamber for easy access to process parts
- Hydraulic clamping system for ease of disassembly
- Minimal holdup volume
- Easy scale-up
- High yield
- Better particle size distribution
- Improved flowability
- Excellent process repeatability
