I Wanted to share a few things with you. I've been asked if my screen works with damp or wet dirt. The short answer is no. The power screen was designed to handle dry dirt. Just like the large vibrating screens. you do not have too many problems with the large opening screen, but when you get to the 1/8" and smaller the holes get pluged up. Then the dirt begins to pack. This can be a real mess. Especally if you were to let the dirt dry out in the screen. Just like a dry washer the dirt must be dry.
Some have asked if the screens could be a different mesh. Yes, you bet, you can select what ever mesh size you want. The gold in Colorado is fine. So, I like to screen thru 20 mesh and use the Blue Bowl. I also process the +20 mesh also. By using the 1/8" screen, in the screen pack, it makes it easier to make the finer cuts. So, if you want a finer mesh, or larger mesh
it is not a problem.
