II. Equipment Configuration and Relevant Technical Parameters I. Main Technical Parameters of the Equipment 1. Equipment Title: Three-in-One Function Film Recycling Granulation Extrusion Line 2. Model of the Equipment: HXSJ150DWM11 3. Applicable Raw Material: Suitable for the recycling and pelletizing of PE, LDPE, HDPE films 4. Production Capacity: 500-680 kg/h, depending on the raw material formula III. Main Technical Features of the Equipment This machine is specialized in the recycling and granulating of HDPE, LDPE, etc. It can handle conveying, crushing, and granulating all at once, saving a lot of labor during the process. The film is heated when crushed, which is beneficial for the plasticity of the material and thus enhances the quality of the final granules and production capacity. The crusher uses a large-power AC motor, allowing even large pieces of material to be fed directly; the main extruder's screw is uniquely designed to facilitate the compression, conveying, plasticizing, and venting of film scraps. For barrel temperature control, it uses an accurate digital temperature controller, large-power cast iron heater, and low-noise cooling fan, working together perfectly to control the barrel temperature and ensure granule quality. Equipped with advanced low-noise reduction gearboxes with hardened gears and forced lubrication, this allows the machine to adapt to high-speed continuous operation. IV.
