Ultra-fine powders have problems during packaging such as high gas content, large dust, low density, floating, and difficulty in filling. This packer completely solves these issues, overcoming low efficiency, poor accuracy, large dust, and packaging difficulty of manual packing. It is a new-era equipment with high weighing accuracy, simple and convenient operation, widely applicable for packaging ultra-fine powder materials. Product Overview: Vacuum valve bag packer is suitable for valve bag packaging of ultra-fine and nano powders with high gas content and low density. The packaging process has no dust leakage, effectively reducing environmental pollution. It achieves high compression ratio filling, making the finished bag full and compact, reducing bag size, with outstanding packaging effect. Representative materials: silicon powder, carbon black, white carbon black, super conductive carbon black, powdered activated carbon, graphite, hard acid salts, etc. Working Principle: JKF-159C series packer uses vacuum suction to feed materials. The bag is placed in a sealed vacuum chamber. Material enters the bag through negative pressure suction, and gas in the material is discharged through bag pores. When the weight reaches preset value, vacuum pump stops, vacuum chamber door opens, and the packed bag is manually removed, completing one bag. Technical Parameters: Weighing range: 1-50kg. Packaging speed: 1-4 bags/min (depends on material characteristics and bag type). Measurement accuracy: ±0.2-0.4%. Voltage: AC220V-440V 50/60Hz three-phase four-wire (customer to provide local voltage and frequency). Air supply: 0.4-0.8MPa dry compressed air, total air consumption 0.4m3/min.
