Product category: Agitator & thickener series

Variable Cross-Section Obliquity Agitator

High Flow. Low Shear.

This agitator delivers high recirculating axial flow with low shear rate while maintaining minimal power consumption. Compared to conventional 45° PBT agitators, it achieves equivalent mixing performance while reducing power consumption by 40-50%.

Designed for phosphoric acid processes and non-ferrous metal leaching applications, this agitator delivers high pumping capacity with controlled shear to prevent excessive crystal breakage, improving downstream filtration and sedimentation performance. Widely adopted by phosphate and non-ferrous metal producers, NHD agitators provide reliable and energy-efficient mixing solutions.
