Impeller Baggers, sometimes called a Turbine Packer, use a spinning impeller to “blow” material into valve type bags. They are ideal for fine, dry, high bulk density (>50#/cuft.) powders of less than 200 mesh where crushing or fines are not an issue. Typically the material flows from the hopper by gravity into the impeller housing where the impellers forced the material into the bag.
Applications are fly ash, carbon black, cement, kaolin, clay, graphite, polystyrene, silica and vermiculite. Impeller baggers can fill 20-100 lbs. bags at 1-12 bags/minute with an accuracy of +/- 2-8 oz.
