ABSTRACT:
A screw-type front extrusion granulating apparatus for forming moistened powdered raw material such as chemicals for use in the agriculture, pharmaceutical, or food industries into granules, has a conveying screw in axial alignment with a semi-spherical die, the die having a plurality of die openings formed therein. The conveying screw has an extrusion blade mounted to its forward end to project into the confines of the semi-spherical die, the contour of the extrusion blade generally conforming to the inner surface of the die. In operation, the moistened powdered material is transported forwardly under pressure by the screw and extruded through the die utilizing the pressure of the screw and the scraping action of the extrusion blade.
