Lab Roll Compactor

Dry Granulation Technic

Application & Process :

The NewLABOrollercompactor machine is used for dry granulation of pharmaceutical ingredients in pharmaceutical industry, in food as well as chemical industry for densification and granulation of powder. The dry compaction of the powder between two rollers on high pressure for increased bulk density, making granules, dust free processing and reducing packing size.

The material in form of powder passes through the two counter rotating rolls of roller compactor under very high pressure. As the volume decreases through the region of maximum pressure, the material is formed into a solid compact sheet or flakes of ingredients. These flakes or compact sheet of ingredients are reduced in size to obtain the desired grain size. The machine takes extra care to prevent the generation of fine during this process.

New Design Features :

  • Designed strictly compliance with the stipulation of cGMP
  • Product contact parts AISI 316/ 316 L Quality
  • Versatile, quick, convenient test for dry granulation characteristics.
  • The test can be run with only a few hundred grams of material.
  • The results obtained can be extrapolated to a production size machine.
  • Compact and portable design allows for set up and testing at a convenient place.
  • Two type model available for lab scale Roll Compactor
    A. Single screw feeding system and B. Double Screw feeding system
