The optimal binder depends on fertilizer composition, process conditions, target granule properties and cost requirements. Lignosulfonates are highly versatile binders that can be used alone or in combination with inorganic binders or synthetic polymers to optimise both granule quality and cost performance. Reach out to our team to learn what is the best binder for your specific formulation.

Yes. Combining lignosulfonates with clay, inorganic acids or synthetic polymers is a common approach to balance granule strength, processability and formulation cost. In many cases, these combinations provide better overall performance than using a single binder alone.

Poor granule strength is often caused by insufficient binder performance, inadequate moisture control or suboptimal process conditions. Selecting the right binder system can significantly improve granule integrity, reducing dust generation and product losses during storage, transport and application.

Using the lowest-cost binder is not always the most economical solution. Higher-performance binders may require lower application rates and produce stronger granules, but can increase formulation costs. Combinations of lignosulfonates with lower-cost binders often deliver the best balance between formulation cost and performance.

The optimal dose depends on the fertilizer composition, production process, moisture level and target granule properties. Laboratory and pilot-scale trials are recommended to determine the most cost-effective dosing rate.

Lignosulfonate binders improve particle adhesion while maintaining good granule integrity. Depending on the formulation and dosage, they can help optimise granule density, mechanical strength and disintegration characteristics to meet specific application requirements.
