Oliver 31 Gravity Separator (Air Table) – Like-New Condition

Maximize your processing purity with this Oliver 31 Gravity Separator. Originally sold to a client for a short-term project, this unit has been returned to us with very low hours and remains in “like-new” condition. This is a rare opportunity to acquire a professional-grade Air Table—the industry standard for density-based separation—without the lead times of a new factory order.

This specific unit was previously utilized in a wheat processing application and comes equipped with a 16 x 16 coated wire mesh deck, perfectly optimized for small grains and fine granular recycling materials.

Versatile Industrial Applications

The Oliver 31 is renowned for its ability to separate materials with minute differences in weight. While currently outfitted for small grains, this air table is a versatile powerhouse across multiple sectors:

1. Industrial Recycling & Reclamation

* Crumb Rubber: Essential for removing fiber and wire contaminants from tire rubber.

* Solar Panel Recycling: Separating glass, silicon, and metals from shredded PV modules.

* E-Waste: Recovering high-value metals from plastic and circuit board regrind.

* Plastics: Sorting various polymer densities (e.g., PE from PP) in flake form.

2. Agriculture & Seed Processing

* Small Grains: Perfect for wheat, barley, oats, and rye.

* Specialty Seeds: Ideal for clover, alfalfa, and vegetable seeds.

* Contaminant Removal: Effectively removes ergot, stones, and light/damaged kernels to improve germination rates.

3. Forestry & Mineral Processing

* Forestry: Separating seeds from cones and removing debris from wood chips.

* Minerals: Concentrating heavy minerals and removing lighter gangue material.

Why Choose This Unit?

Buying a “like-new” Oliver 31 allows your operation to scale quickly with a lower capital investment. The 16 x 16 coated wire mesh provides a durable, non-stick surface that ensures consistent fluidization of the product bed, resulting in a cleaner “middle cut” and higher-quality end products.
