1) Weighing range: 25-80kg/bag
2) Packing speed with double stations: 16-20 bags/minute, packing speed with four stations:32-40bags/minute ( packing speed depends on different materials and different packing bags)
3) Weighing error: ≤±0.2%/bag
4) Pulling speed: 10kilometers/hour
5) Net weight of the whole machine: about 4800Kg
6) Designing voltage: AC220～440±10%、50Hz ( customers should finalize local voltage and frequency)
7) Total power: 16-20kilowatt /set
8) Air source: pressure 0.5-0.7Mpa; dry compressed air, air consumption: 1.5 m3/min/set
9) Suitable environment: altitude: ≤2000meters, ambient humidity: ≤95% Non-congealable Dew, operating temperature：-30℃～50℃、storage temperature：-45℃～80℃
10) Feeding method: gravity free flowing
11) Operating efficiency： Continuous working 24 hours, it needs 4 people to operate this machine.
12) Packing and weighing method: Manually applying bag, automatic clamping bag, automatic weighing, automatic filling, and manual sealing bag and with pulling hook.
The materials are conveyed into hopper by conveying unit and fed in big, middle, and small feeding speed through pneumatic arc gate. When materials in weighing hopper reach preset value, load cell sends signal and arc gate closes, the discharging valve on the bottom of weighing hopper opens, then materials are immediately fed into bag. Clamping unit opens, packed bags are conveyed to sealing unit by conveyor and the system will return back to original station and begin next packing.
