GK-60 Pharmaceutical Roller Compactor with Dust Collector GK-60 Pharmaceutical Roller Compactor with Dust Collector

Roll Compactor (RC Machine) , we usually called it dry granulator in Chinese , it is a versatile densification and dry granulation machine that produces uniform compacted sheets with consistent hardness and increased density by compacting powdered material between two uniquely designed rolls.

The GK-60 roller compactor is a clean type, a vertical product flow system uses a tapered feed screw to deliver the material to the fully contained compaction zone of the cantilevered rolls, increasing product yields and minimizing product fines. Roll compactor utilizes a unique roll system to compact powders into sheets or briquettes. The compacted sheets are milled to produce granules of a specific 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.

1. Material is fed between two counter-rotating roll presses.
The rolls apply extreme pressure, to press the material into a sheet-like form.
This sheet of material is then fed through a granulator, where it is broken up into uniformly sized granules.
Output is depended upon the mesh size and material density.

1.  No water or any organic solvents. Therefore, this method is especially attractive for drugs, which are moisture or heat sensitive.

2. Suitable for compounds that either have a low melting point or degrade rapidly during heating, as the method does not involve any drying step.

3. Forming porous tablets thus allowing water to penetrate more easily into the tablet. This leads to improved disintegration behavior of tablets.

4. Roll compaction technique provides an efficient and easily automated process, which is environmentally friendly.

5. Low operational cost.

6. Dust problems are minimized or avoided and the die filling during tableting is improved.

7. Roll compaction/dry granulation can be used, if the drug or the excipient is poorly flowing or sensitive to heat or moisture.

8. It can also be used for densification of powders prior to encapsulation.

9. Control particle hardness and provide granule integrity during conveying and processing steps.

10. Control dust and reduce environmental risk, waste and cross-contamination.

After granulation(Different materials in different application). It is ok for testing raw material if you can send sample to us.
