Norlig performs better than molasses in limestone and gypsum

Borregaard’s Norlig® lignosulfonate binder and molasses were compared at two dosage rates using three performance parameters.  The products were evaluated in both limestone and gypsum.

Results show that Norlig is the more efficient binder to improve granule/pellet hardness and reduce dusting from attrition in limestone and gypsum.

Key takeaways:

• Norlig outperformed molasses in reducing fines from attrition.
• Moisture uptake was similar between the two binders at the same dosage rates.
• Norlig improved crush strength significantly over molasses.
