| Powder Coatings are used to provide corrosion or weather resistance to metal or plastic parts. Most often they act as a primer coat for "high gloss" finishes. They also may be used as an electrical insulator. Powder coatings typically contain vinyl, epoxy or nylon powders. Screening of the material is necessary right after the milling or prior to packaging. The problem which occurs during this process is that the material is so fine that screen blinding occurs, significantly reducing throughput. The Sono-Energy and Sono-Wave Systems eliminate this problem through the use of ultrasonic vibration, which is introduced to the screen wire mesh. This secondary vibration deblinds the screen allowing the material to flow freely through from deck to deck. |

APPLICATION 1:
Manufacturers of powder paints for the automobile industry were having problems keeping their screens clear, significantly reducing their throughput. After trying various basic screen cleaning devices, they contacted Sweco. After several tests in the Sweco lab, it was determined that the best course of action would be to add a Sono-Energy System to their round separator. The secondary vibration to the screen helped to clear the screen openings of any particles which had accumulated in the mesh. The blinding, and thus, the throughput issues were resolved simply by adding the ultrasonic technology to existing machines.
Screen blinding can bring your process to a screeching halt. Sweco can help to prevent you from wasting money due to poor efficiency of your separators. Contact a Sweco professional today. |
