Granulation auxiliary binder is a key material used in the granulation process to promote the agglomeration of raw material powders, improve granulation efficiency, and enhance the physical properties of granules (such as strength, surface morphology, disintegration resistance, etc.).
Function of Binder
Enhance Granule Strength: The binder can fill the gaps between granules, strengthen the bonding force between particles, improve the wear resistance and impact resistance of granules, and extend their service life.
Improve Granule Surface Properties: The binder can enhance the smoothness of the granule surface, improve granule fluidity, reduce the friction coefficient of the granule surface, and minimize wear between particles.
Optimize Granulation Process: The binder can increase the efficiency of granulation equipment, reduce energy consumption, improve the stability of the granulation process, and lower the failure rate.
Selection of Binder
When selecting a binder, factors such as its adhesion, surface tension, solid cross-linking strength after drying, cost, impact on crops, and biodegradability must be considered.
Different types of binders are suitable for different granulation processes and raw materials. For example, water-based binders are suitable for aqueous granulation processes, while oil-based binders are suitable for oil-based granulation processes.
Environmental Impact
The production and use of binders may generate pollutants such as wastewater, exhaust gases, and solid waste, which have a certain impact on the environment.
Choosing environmentally friendly binders, such as bio-based binders and waste-recycled binders, can help reduce environmental impact.
In summary, granulation auxiliary binders play a crucial role in the granulation process. Selecting the appropriate binder is of great significance for improving granulation efficiency, enhancing granule properties, and reducing environmental impact.
