II. Equipment Configuration and Relevant Technical Parameters I. Main Technical Parameters of the Equipment 1. Title of the equipment: Three-in-One Function Film Recycling Granulation Extrusion Line 2. Model of the equipment: HXSJ150DNM11 3. Applicable raw material: Suitable for the recycling and pelletizing of PP film. 4. Production capacity: 500kg/h--650kg/h depending on the raw material formula. III. Main Technical Features of the Equipment This equipment is mainly used for (PE PP) film material regeneration granulation. The unit integrates raw material conveying, extrusion granulation, and other functions. The production process saves the labor of repeated transportation of raw materials, is conducive to compression plasticization, and greatly improves production capacity and plasticizing quality. The crushing barrel is driven by a high-power AC motor, allowing bulk materials to be directly fed without a crushing process. The screw structure of the main extruder is specially designed, which is conducive to the compression, transportation, plasticization, and exhaust of the film crushing materials, improving granulation quality. Barrel temperature control adopts digital high-precision temperature control meters, high-power cast iron heaters, and low-noise cooling fans to precisely control barrel temperature, ensuring material plasticizing quality. Equipped with an advanced hard-tooth surface with low noise and forced lubrication reducer to ensure the main machine is suitable for continuous running at high speed. V.
