Roll Compactor- PRC-300 x 330

Powder Dry Granulation Process Technic

Application & Process :

The Roll Compactor machine is used for increased bulk density, making granules, dust free processing and reducing particle size of pharmaceutical ingredients in pharmaceutical industry, in food as well as chemical industry for densification and granulation of powder.

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.

  • Free flowing granules for Automatic packing
  • Compact granules to reduce package size
  • Dust Free granules to facilitate handling
  • Granules to fill in smaller capsule
  • Granules for Tabletting.
