The extrusion-spheronization pill making technique is one of the most effective methods for preparing pellets. This technology is mainly used for extrusion and spheronization of materials that are highly absorbent and contain less sugar and fat. Practice has proved that the products made with this technical equipment have uniform and round pellets, and the quality is obviously better than products produced by other technical equipment. The technical equipment is suitable for wet preparation of various specifications of pellets in the pharmaceutical, chemical, food, feed, electronics and other industries. The technical equipment consists of two functional units: an extrusion device and a rounding device. Its speed is frequency control.
