The powder valve port packaging machine impeller feed valve port packaging machine is suitable for ultra-fine powder material the heap large proportion of the size of the powder and small particles of material. Is characterized by speed packaging. Representative of the materials, such as cement, dry mix mortar, diatomite, perlite additives, calcium carbonate, silica fume and other materials. Technical parameters: · Weighing range :10-50kg · Packing speed :3-6 bags / min (determined according to the different characteristics of packaging materials and packaging bags), measurement accuracy: ± 0.2-0.4% · applicable voltage: AC22OV -440V 50/60HZ three-phase four-wire (Customers are required to provide local voltage level and frequency) · Air requirement: pressure 0.4-0.8MPa dry compressed air, the total air consumption 0.8m3/min · applicable environment: ≤ 2000 meters above sea level , the use of ambient humidity ≤ 95% (non-condensing) Operating temperature 0 ℃ ~ 50 ℃, the design of the storage temperature of -20 ° C to 70 ° C 3. The working principle: DSC-FY series packaging machine, material from the finished products warehouse by pneumatic butterfly valve at the top of the surge bin or star feeder into the the buffer silo, then feed inverter control impeller whirling material to the valve pocket. Packaging through the feed valve to control the quantity, packaging bag material reaches the preset target weight when filled to feed the impeller stops running, the feed valve closed folder bag open through the control system, manually remove packed bag is completed in a single bag. FY packaging machine weighing instruments can choose GW / NW packaging. 4.
