Low Cost, High-Frequency, Screen Deblinding – Turbomite Deblinding System

By Jeff Hochadel

­­Several weeks ago, I was reading an article in one of the technical journals discussing the variety of ways to eliminate screen blinding on vibratory equipment. The article discussed a number of “old school” solutions such as rubber balls, clean rings, spray nozzles and brushes. These methods have been around for decades and produce a low to moderate level of success in keeping the screen surface from blinding or clogging. The article also discussed the most effective solution for screen deblinding – Ultrasonics. While it is the most effective, ultrasonic deblinding systems are also the most expensive. If you are not familiar with ultrasonics Read More…

While this is my first post and I have a lot of interesting applications to discuss, I want to begin with a recent application where a customer was using ultrasonic sieving to screen a high-value ceramic powder used in the electronics industry.  The screen mesh was fairly coarse – 80 mesh. The ceramic powder was agglomerating and forming hard nodules of ceramic material from the current supplier’s ultrasonic system. The customer could not tolerate these hard nodules contaminating the final product. They approached us for a solution.
