The Sono-Energy creates a secondary ultrasonic vibration that prevents blinding on fine meshes (60-635 mesh). Numerous applications exist for epoxy powder, toner powder and powder paints. Sono-Energy also works well on heavy density powdered metals, including lead, nickel and chromium, by preventing lodging on near-size particles therefore reducing blinding, and prolonging screen life.
