For a couple of years i have been thinking of building a small gravel screen plant, for limited production; if it screens a couple of hundred yards each year that would be it.
Have several designs on paper, the one I want to build is:
Screen deck is 9 ft long 8 feet wide (two 4x9 screens aside each other).
Slope of 40 degrees
collection box 8 ft wide 11 ft long
6,000 lb axle from old trailer on rear and hitch on front.
The screen deck will be attached to the front of the collection box via heavy duty bushings and pins (like from a 312 cat bucket) at each corner. This will allow the screen deck to move up and down as its shaked.
The top of the screen frame would have a spring under each corner on top of a steel post raising up from the collect box.
The shaking would be from a vibco electric viabrator mounted under the top of the screen frame below the screen cloth.
The screen frame would be able to be lifted up by 2 cy loader to empty what is stuck on top of it (it being hinged at the bottom).
Under the screen cloth would be heavy steel bars to act as a grizzly.
Gravel will have rocks up to 24 inch size placed on the screen frame.
My question amoung others is will the bushings and pins at the bottom of the screen frame where it will be connected to the collection box work?
All the other screen boxes I have seen have springs at each corner for the screen frame (4 springs).
Basicly its a grizzly with a 40 degree slope deck and screen cloth on top of the grizzly bars and a vibrator to shake the deck so the gravel will not always get stuck on the screen cloth.
Screen cloth 1 inch opening.
Any comments made will be greatly appreciated.
Do you know of a gravel screening and crushing forum that i could post my question to?
