solids - products and services

Auger filling of powders and granules to bottles or jars 

We can blend powders in batches from 500kg to 1500kg using a ribbon blender or Nautamixer. Raw materials are input from kegs, sacks or FIBCs and liquids can be added if required. 

With a batch size of 500kg to 1000kg, depending on bulk density, impregnated or coated granules can be produced in a rotary drum blender. The addition of liquids is achieved by spray nozzles with air micronisation if required, while inter-process transfer is achieved by the 'tote' bin system.

Solids Packing
We can pack container sizes from 50gms to 1000kg with high-fill accuracy. We can also pack kegs, drums and sacks up to 25kg.
