  • For combination with:–
    - bagging lines
    - big bag filling systems
    - valve sack packing machines
    - form fill Seal bagging machines
    - batching and mixing plants
  • A range of scales to suit your product and throughput
  • Loadcell weighing motionless and maintenance free
    Two stage filling - coarse and dribble feed
  • Dosing device to suit characteristics of your product
  • Catch gate for positive product flow cut off when weighment is reached
  • Dialog 165 weighing controller (see weighment and control) recognises changes in product flow and density
  • Memory for 63 different weighment programmes
  • Self optimising software for high accuracy and maximum speed
  • Auto regulation of “in-flight” material
    Accuracy +/- 25g (Sigma 2 - 95.5% of weighments, can be achieved)
  • Auto calibration and self test, auto tolerance check with alarm display
    Output of weighment data to PC or printer
  • The weighers are mounted individually or as double/duplex unit
  • Enquire about availability of second hand scales

Standard Options:

Two stage dosing device to suit your product and throughput:-

Gravity catch gate/shutter dosing:

  • For free flowing granular and crystalline products which do not bridge
