1 Product Overview: impeller feed valve port packaging machine suitable for ultra-fine powder material, Bulk density, smaller particle size of the powder and granular materials. Characterized by fast packing. The representative materials such as cement, dry mix mortar, diatomite, perlite additives, calcium carbonate, silica fume and other materials. (2) Technical parameters: · Weighing range :10-50kg Packing speed :3-6 bags / min (according to the characteristics of the packaging materials and bags of different decision) · measurement accuracy: ± 0.2-0.4% · Applied voltage: AC22OV -440V 50/60Hz three-phase four-wire (customer must provide the local voltage level and frequency) · Air source: pressure 0.4-0.8MPa dry compressed air, total air consumption 0.8m3/min and for the environment: ≤ 2000 meters above sea level , ambient humidity ≤ 95% (non-condensing) Operating temperature 0 ° C to 50 ° C, the design storage temperature -20 ° C to 70 ° C 3. Working principle: DSC-FY series packaging machines, materials from finished products warehouse by the surge bin above the the pneumatic butterfly or star feeder into the buffer silos, feed impeller and frequency control the rapid rotation of the material to the valve pocket. By feeding the valve control feeding amount, filled to the packaging material of the bag reaches the preset target weight, to feed impeller stops running, feed valve is closed, the folder bag is opened by the control system, manually remove The packed Liaodai, that is completed in a single bag. FY packaging machine weighing instruments can choose GW / NW packaging.
