Keeping your sifter in top shape
Because a sifter rotates, vibrates, gyrates, or reciprocates at high speed, it's subject to high levels of mechanical stress. You can keep your sifter in top shape by regularly inspecting and servicing it. Find out how to do that in this article, which expands on sifter information the author covered in his previous article "Selecting a sifter for scalping, removing fines, or grading" [Powder and Bulk Engineering, December 2000, pages 19-33].
To perform up to your expectations, a sifter [also called a screener] must provide sharp size separations and consistent discharge to your downstream process. But this kind of sifting performance won't happen if you don't pay regular attention to how your sifter is behaving -- what’s going into it, what’s coming out, and how the sifter looks and sounds.
