SHAPE 'Loss In Weight' Feeder Range:

SHAPE can supply a range of 'Loss In Weight' Feeders utilizing either Screw Feeders or Vibratory Feeders.


These feeders work on the principle of controlled extraction of a material from a hopper, which forms an integral part of the LIW feeder and can be designed to provide either continuous or batch 'loss in weight'


Advantages of LIW System's are:

  • Feed rates can be maintained within tighter tolerances even with variations in bulk density, which can occur with different suppliers of the same powder.
  • Controls can be supplied with an HMI configured to show the process, whether it be a single or multiple machine operation.
  • The ability to set high and low level alarms on the feed rates. This gives a fail safe to the process and prevention of out of specification products.
  • Use of a totaliser system in the software this can log the total quantity of material fed on a timed basis (shift, day or month) and so assist with the inventory control of the process.
  • Remote control of the system to set rates.


Dust explosion prevention or protection may be required on systems handling dry powder or granular materials. To operate without proper explosion venting may result in fire or explosion. check local industrial codes and policies or consult SHAPE.
