Super Fines Classifiers

Super Fines Classifiers - Blue Chip Series

The Nesans Blue Chip Series Super Fines Classifier is a high-efficiency fines recovery system designed to reclaim valuable ultra-fine material lost from existing sand washers or classifiers. Acting as a post-processing unit, it captures the fines that typically escape into sedimentation tanks—turning process waste into usable plaster sand or filler material.

Built around a cluster of precision-engineered hydrocyclones, the Blue Chip Series uses centrifugal force to separate ultra-fine particles from slurry overflow streams. This makes it an ideal add-on solution for plants that suffer from poor fines recovery due to conventional washing equipment, helping to maximize resource utilization and reduce sludge generation.

With its compact footprint, energy-efficient operation, and easy retrofit design, the Blue Chip Series offers a cost-effective path to improved plant yield and environmental sustainability. It’s the preferred choice for operators who want to recover more, waste less, and get the most out of their existing setup.

How It Works

The Nesans Blue Chip Series Super Fines Classifier operates on the principle of centrifugal classification using a hydrocyclone cluster. Slurry overflow from an existing sand washer or classifier—typically rich in ultra-fine particles—is diverted into the Blue Chip system. This slurry is then pumped under pressure into a bank of high-efficiency hydrocyclones.

Inside each cyclone, the slurry undergoes high-speed rotational flow, generating centrifugal forces that push heavier fine particles outward toward the cyclone walls. These usable fines are then discharged through the underflow, while lighter silt and unwanted ultra-fines exit via the overflow to waste or further water treatment.

The recovered underflow, rich in usable plaster sand or mineral fillers, can be routed to a dewatering screen or chute for final processing. This setup ensures maximum recovery of saleable material, reduced water loss, and lower sedimentation tank loading, making the Blue Chip Series an efficient and sustainable enhancement to any sand washing circuit.
