Ok, I tell people all of the time that its cheaper for me to just get rid of their old rock and put in new. I am a firm believer in that and usually I just dump the old as fill or in gravel drive areas. I have a project where I will be removing about 88 tons of rock and was wondering if any one has ever made a top soil screener and just sized the screen to keep the river rock on top so I could sort out all of the small dirt and debris from the rock and then be able to reuse it for jobs down the road. I don't want to do this by hand as its not worth the time but if some one has done this with a screener and a skid how well did it work? was it worth it in terms of how clean the rock got?
