II. Equipment Configuration and Relevant Technical Parameters I. Main Technical Parameters of the Equipment 1. Title of the equipment: Horizontal Type Water Ring Granulating Extrusion Line 2. Model of the equipment: HXSJ140DW 3. Applicable raw material: Suitable for the recycling and pelletizing of HDPE and LDPE crushed material. 4. Production capacity: 400-450kg/h depending on the raw material formulation III. Main Technical Features of the Equipment This Horizontal Type Water Ring Granulating Extrusion Line is specialized in recycling and pelletizing HDPE crushed material. The specially designed screw structure can effectively eliminate moisture and volatile gases during the melting process, resulting in uniform, firm, and beautiful pellets as well as high production efficiency. Using an advanced low-noise hard-toothed surface reducer with forced lubrication ensures the main extruder adapts to high-speed continuous operation. The plastic cutting method involves scraping by a blade in the melt condition and cooling solidification by circulating cooling water. After high-speed drying, it can effectively remove the finished product's moisture and achieve good drying effects. The cutting process is simple to operate, has a high degree of automation, no dust, low noise, good quality slices, and an attractive appearance. IV. Appearance Schematic of the Equipment V.
