Continuous salt crystal separation and dewatering with low residual moisture and high machine availability.
This solution applies a two-stage pusher centrifuge for continuous salt crystal separation and dewatering. It suits sea salt, rock salt, and industrial salt. The multi-stage design enables optional in-machine washing and lowers discharge moisture to reduce downstream drying load.
