Lab Roll Compactor (Laboratory Roller Compactor Machine)

Lab Roll Compactor (Laboratory Roller Compactor Machine)

Compaction of powder products is an important process in the size reduction of the powdered particles. The New LABO roller from the range of Shree Bhagwati (India) Pvt. Ltd comes with easy to use features and is widely used by big pharma players in the country and abroad as well.


The new laboratory roller compactor 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.
