couple of questions what do your think of this project, YOUR COMMENTS WILL BE GREATLY APPRECIATED.
would like to build a small grizzly screen.
planning on a deck slope of 30 degrees.
will use electric vibrator to shake grizzly bars, like on a dump truck box but vibrator designed to operate continuous.
thinking of the grizzly bars to use, 1 inch round solid bars with 2 or 3 inch spacing between bar edges.
bracing under grizzly bars will be located 18 inch from top of deck then another 18 inches and another 18 inches, then one half of the rest of the distance.
1 inch round bars can be purchased in 20 foot lengths so length of deck will be 6 feet 6 inches,that should be long enough for the sand to fall through before reaching the end of the screen deck.
Width of deck would be 10 feet my two yard bucket wheel loader is just under 8 feet wide.
height will be 9 feet dump clearance at full dump.
box frame will be 3 inch square tubing 1/4 thick wall with 3/16 plate on sides.
if I want to screen smaller material I could place a wire mesh on top of the grizzly rods.
I expect the largest rock that would occasionally be dropped on the grizzly bars would be around 18 inches. May be a 2 foot fall at most.
Most rocks would be 12 inches and under, any thing larger then 18 inches I would waste off to the side in the pit.
What do you think, what would you do differently.
Think it will work and what problems do you see?
