Unlike traditional wet granulation systems, the GK Series roller compactor uses mechanical compaction force to densify powders into compacted ribbons, which are then milled into uniform granules. This advanced technology ensures bulk density improvement, enhanced powder flowability, and excellent particle size uniformity, even for difficult-to-process and moisture-sensitive materials.
With its GMP-compliant equipment design, precision roll gap control, and robust hydraulic pressure system, the GK Series dry granulator has become a preferred choice for modern continuous manufacturing lines.
What Is Roller Compaction Granulation and How GK Series Works
Roller compaction granulation is a dry granulation process that transforms fine powders into free-flowing granules through controlled mechanical compression. In the GK Series dry granulator, powder is fed evenly into the compaction zone, where it is compressed between two counter-rotating rollers under high pressure.
Working Principle of GK Series:
• Powder enters the feed system uniformly
• Vacuum deaeration removes trapped air to improve densification
• Rollers apply controlled compaction force
• Dense ribbon flakes or compacted ribbons are formed
• Ribbons are milled through an oscillating mill
• Granules with controlled size distribution are produced
This dry granulation process eliminates the need for drying steps and significantly reduces production time, energy consumption, and operational complexity.
