White carbon black, silica vacuum quantitative valve port packaging machine 03358050535 Qinhuangdao Puda Electronics Co., Ltd. qq537580429 
 Technical parameters: 1, Specifications: DCS-FVCA, the DCS-FVCB, the DCS-FVCC 
 Packing speed: 1 to 4 bags / min 3, the measurement accuracy: ± 0.2 to 0.4% 
 4, measurement range: 10 ~ 25kg5, Applicable materials: Bulk density is 0.04 ~ 0.3T/m3 very light to very fine powder, such as flue gas of silica fume, carbon black, white carbon black, stearic acid salt, graphite . 
 Product Features: vacuum valve port packaging machine adopts the HYAAC 
 Weight monitoring and control systems, including micro-processing, ability to multi-menu, the checkweigher feedback, packaging statistics, key school scales and password protection, and optional vacuum pump and filter bags. With butterfly bulk material sorting gate valve, start air rotation and standard inflatable material Tsui tube. The vacuum packaging machine with its optimized structure design, high quality components to meet the highest level of industry standard. How it works: material into the packaging system by gravity or passive mode to load the bag 
 Bags by the negative pressure within the vacuum chamber in the bag material gas discharged after the materials remain in the bag, and a vacuum unit to adjust the pressure of the vacuum chamber in the inverter control. Feed valve size of the two fields control the material flow, bringing the completion of a packaging process.
