Jones + Attwood^™ Screw Classifier

Efficient Grit Separation and Dewatering

The Jones + Attwood^™ Screw Classifier is a free-standing, stainless-steel system that isolates mineral grit from organics while simultaneously dewatering and elevating it for convenient dumpster discharge.

Working in tandem with an industry-standard hydro-cyclone, the unit captures at least 95% of grit larger than 150 mesh (≥ 2.65 sg), protecting downstream pumps and clarifiers from abrasion and settling issues.

Hundreds of installations worldwide attest to its reliability, high-capacity drive, and maintenance-friendly design.

THE PROBLEM

In many industrial and wastewater treatment applications, the presence of mineral grit can cause significant operational challenges. Grit accumulation can lead to equipment wear, reduced efficiency, and increased maintenance costs.

THE OVIVO SOLUTION

The Jones + Attwood Screw Classifier is designed to tackle grit accumulation issues head-on. This classifier provides a robust and reliable solution for the effective separation and dewatering of mineral grit, ensuring smooth and efficient operations.

HOW IT WORKS

The Jones + Attwood Screw Classifier operates by integrating with industry-standard hydro-cyclones.

Hydro-cyclones reduce water volume, allowing mineral particles to settle in the grit separation unit. These particles are then elevated by the screw mechanism, dewatered, and discharged efficiently by the grit dewatering classifier.
