Granulation Equipment
Granulation equipment transforms fine powders into larger, more uniform granules or pellets. This improves handling, reduces dust, and enhances performance in applications like fertilizers, chemicals, and minerals. Technologies such as rotary drum granulators, disc pelletizers, roller compactors, and melt granulation systems are selected based on material behavior, binder requirements, and desired particle size. Granulation is a key step where bulk solids are given the form needed for transport, storage, and end use.
Rotary Drum Granulators
Rotary drum granulators are large, rotating cylinders that agglomerate fine powders into uniform granules through a combination of tumbling motion, moisture, and binders. They are extensively used in fertilizer, mineral, and chemical production. Known for robustness and continuous operation, they handle large capacities with high efficiency.
Disc Pelletizers (Pan Granulators)
Disc pelletizers (or pan granulators) use a rotating inclined disc to form round, uniform pellets. They are highly flexible, enabling operators to adjust disc angle, speed, and moisture for tight size control. Applications include fertilizers, iron ore, and specialty chemicals, where they are valued for high uniformity and easy scale-up.
Melt Granulation Systems
Melt granulation uses a low-melting binder that liquefies during processing, binding powders into spherical granules. This technique is widely used in pharmaceuticals, agrochemicals, and specialty foods, offering improved flowability, compressibility, and controlled release properties. It eliminates the need for external solvents, making it a clean, efficient process.
Roller Compactors
Roller compactors compress fine powders between counter-rotating rollers into dense ribbons or flakes, which are then milled into granules. This dry granulation process is essential for moisture- and heat-sensitive materials such as pharmaceuticals, fertilizers, and specialty chemicals. Advantages include no need for binders or solvents, consistent particle strength, and cost-efficient operation.
