How does Dry Granulation Machines Work?
Dry granulation technology in the process of granulation with high pressure granulation, the powder is pelleted to a dense state by applying external force in a limited space. The forces that produce stable agglomeration include bridging force of flocs, cohesive force of low viscosity liquid, surface force and mutual cohesion force. The success of dry granulator operation depends on the effective utilization and transmission of external force on the one hand, and the physical properties of granular materials on the other hand. Dry granulator is a new organic fertilizer granulation process developed from traditional wet mixing granulation. Dry granulator is a kind of granulation process that uses crystal water of material itself to compress, shape and granulate raw material powder directly through mechanical extrusion. As a main branch of powder process treatment, dry granulator is becoming more and more important with the improvement of environmental protection requiremen...
