The operator inserts the bag to the bag clamping chute and presses the foot Switch. A pneumatically operated bag clamping arrangement will clamp the bag.
The controller automatically tares the gross weight of bag to obtain a Net weight. The material is then fed into the bag, a two-posit ion sector gate controls the rate Of feed.
The controller compares the actual weight with the target weight settings, when the Main/Coarse feed setting is reached the main feeder of the sector gate is Latched, feeding continues in the Fine feed mode.
The material is fed in the fine feed mode until the Final Weight minus In-Flight value is reached, after which the Fine feeder is closed.
Once the feeding is stopped a settling time (adjustable time, varies from 500mts to 2 sec) is given after which the end of batch is signalle, automatically the Totalized and Bag counter is updated.
