Working Principle
Under compression force, dry materials agglomerate into dense and hard compacts (cake‑shaped materials) through compaction. The compacts are further crushed and sieved to obtain granular products, which is the granulation process. Compaction removes air between particles and brings particles into close proximity, generating bonding forces such as van der Waals force, adsorption force, crystal bridge and interlocking connection. The strength of compacted granules mainly relies on intermolecular forces.

Technical Parameters



Product Features
● High Granulation Yield
Dry granules feature uniform density, good disintegration performance and high yield. The special feeding structure ensures consistent material feeding.

● No Secondary Drying Required
Water‑circulation cooling for rollers prevents material sticking to roller surfaces. No wetting agents such as water or ethanol are required, and no secondary heating‑drying step is needed to simplify workflows.

● Sealed & Low‑Dust Operation
Sealed operation realizes low contamination and meets sanitary requirements for pharmaceutical products. It is especially suitable for granulation of materials which cannot be processed by wet granulation.

Product Applications
● Fertilizers
Potassium sulfate, potassium chloride, Russian red potash, potassium nitrate, ammonium chloride, mono‑ammonium phosphate, di‑ammonium phosphate, NPK compound fertilizer, imported Russian potassium sulfate, phosphate rock powder, ammonium sulfate, triple superphosphate, humic acid, etc.

● Powder Materials
Zinc oxide, desulfurization gypsum, lead oxide, calcium chloride, calcium phosphate, high‑test hypochlorite, cryolite, antioxidant, white carbon black, isophthalonitrile, etc.
