Precipitated Silica Packaging Machine

Ultrafine powders in the packaging process often have issues such as high air content, large dust, light specific gravity, floating tendency, and difficulty in compacting. This packaging machine completely solves the above problems, overcoming challenges of manual packaging like low efficiency, poor accuracy, heavy dust, and difficult handling. It represents a new generation of equipment with high weighing accuracy and simple operation, widely applicable for packaging ultrafine powder materials such as precipitated silica, precipitated white carbon black, thickeners, pigment carbon black, acetylene carbon black, ink carbon black, rubber carbon black, activated carbon black, carbon, calcium stearate, zinc stearate, magnesium stearate, heat stabilizers, calcium-zinc stabilizers, barium-zinc stabilizers, magnesium hydroxide, aluminum hydroxide, powder coatings, carbon black, matting powder, stearates, lithium iron phosphate, aerogel, and other powders. Product Overview: The vacuum valve port packaging machine is suitable for valve bag packaging of ultrafine and nano-scale powders with high air content and low bulk density. The packaging process has no dust spillage, effectively reducing environmental pollution. It achieves high compression ratio filling, making the finished bag shape full and reducing bag size, resulting in particularly outstanding packaging effects. Representative materials include silica powder, carbon black, white carbon black, super conductive carbon black, powdered activated carbon, graphite, and hard acid salts. Working Principle: The JKF-159C series packaging machine feeds material by vacuum suction. The packaging bag is placed in a sealed vacuum chamber, and materials enter the bag through negative pressure suction, while gas in the material is discharged through the bag pores. When the weight of the filled material reaches the preset value, the vacuum pump stops, the vacuum chamber door opens, and the operator removes the sealed bag, completing one bag packaging.
