Looking to purchase a portable screener. Looking for recommendations on what to buy or what not to buy. Had a screen machine spyder at one time and liked the concept but it seemed like the screen action was sub standard. I'm leaning toward a track model. Need 2 deck with a grizzly. Will not be screening topsoil, have a trommel for that. Will be sand gravel and rock. Probably go 1-3/4 on top screen and 3/4 on bottom most of the time. Would like to do about 200 TPH average. Would be feeding with a 350 excavator or 4 yard wheel loader. Looking for input.
