Pneumatic Blending Systems

Gentle, quick, clean & efficient

Pneumatic blending is one of the quickest, cleanest and most efficient methods of obtaining homogenous batches of powdered, granular, or abrasive materials in transporters, atmospheric bins, or storage silos. Unlike a conventional blender, a pneumatic blender puts the user in control by providing the ability to customize a blending cycle that best suits the application.

Nol-Tec’s Pneumatic Blending – the difference

Nol-Tec’s Model 244 and Model 277 Pneumatic Blenders are equipped with either six or 12 wear-resistant aerators mounted around a housing cone. When the aeration valves are pulsed, gentle blasts of compressed air are injected into the center of an unblended batch at various angles to gently and continuously lift the materials upward and outward until the blending target is achieved. The blending action can be optimized by adjusting the air pressure, air pulse frequency, or on/off duration.

Built with few moving parts, Nol-Tec’s pneumatic blenders have long service lives and require minimal maintenance.
Aeration valve assemblies are externally accessible and can be quickly and easily repaired or replaced on-site.
