Fast filling is achieved by hi-speed impeller box and good accuracy is obtained by using a three position cylinder, which enables filling in the bags to be done in steps. Initially the bag filling is done in main feed (faster filling) upto approx. 90-92% of desired weight, in around 6 sec and balance 8% of material is filled in minor feed in 2 secs, ensuring good accuracy and consistency.
