Product Description


SZL series screw dome extruder granulator is used for wet granulation, which mainly consists of drive motor, feeding hopper, extrusion screw and perforated plate. Wet mass is fed into the feeding hopper by gravity or screw. The extrusion screw (single or twin screw) transport the wet mass to the extrusion zone where it is extruded through a perforated plate to produce well formed, cylindrical extrudates of a controlled diameter. The extrudates break off by their own weight or rotary cutter and are collected for the next processing step. The diameter of extrudate is adjustable by changing perforated plate. 


SZL series screw extruding granulator has been commonly used in pharmaceutical, food and chemical industries for making granules with wet mass usually before spheronization.
