Fine Mesh Powder Screening Archives | Solutions In Motion

The finer the screen or sieve used, the better or smoother the finish. Depending on the application, screening can range from simply pouring the slip or slurry through a filter bag with a relatively coarse mesh to using vibratory screeners with finer mesh sizes – down to 120 mesh or maybe finer. This is where the difficulties begin.
