I removed the SS screen and found the bottom side to be plugged. The top looked and felt clean but the angular material was packed into openings and were protruding out past the screen bottom... I couldn't see this condition until I removed the screen. The next generation tailing sluice will have removable screens... I replaced the SS w/ a poly/nylon material with a similar size 58 mesh and ran some material last weekend. You can see the video here

The nylon screen started to fail after 67 buckets. It could still run a few more buckets, but I would say under my conditions a nylon screen would get approximately 70-75 buckets of use. What I've learned from this issue is to design the next tailing screen with removable (quick change) screen trays so that field maintenance or replacement is possible. I would not rule out the use nylon but steel lasts much longer (500 buckets +) but both the top and bottom surfaces of the steel screen must be accessible and cleaned as required to prevent plugging.

Removable screens...... and periodic cleaning from the under side first to loosen the jams then most of the material can be brushed off of the top side.  Be careful when cleaning the top side so that particles will not be driven deeper into the mesh. 

Good luck
