ROCO X3 Rinser (The Roach) CALL FOR PRICE The Roco X3 ticks all boxes required, compact for shipping, fully independent screening unit on a tracked mounted chassis, and conveyor belts that were all hydraulic folding so setup was quick and easy. Roco’s X3 would come fitted with a fully remote control hydraulic tipping reject grid with 4″/100mm grid bar spacings which mean it can feed the screening plant directly with a wheel loader without damaging the feed belt, as the grid would reject the oversized heavy material. From there the 4″ minus material would be fed by an independent feeder system onto another feed belt that would then bring the dirt material to the two-deck vibrating screen box where it would get washed down and segregated into the correct discharge conveyor areas. We manufactured the first-ever rinsing kit for our X3 model and modify the unit so that it could be used for wet screening. We installed a new bespoke heavy-duty 10″/250mm manifold on the side of the feed conveyor, above the screen box area which would take a high volume water feed from a large water pump on-site. This manifold would then distribute the water to the many hoses and wash bars installed on the screen box. The water could then be regulated by adjustable taps on each outlet if required. The two-deck vibrating screen box was modified at the crew’s request as we fitted adjustable angle spray bars and nozzle heads to create higher water pressure for cleaning the material. Nine spray bars were installed, four to the top and four to the bottom deck of the screen box, and we fitted a single spray bar at the end of the feed conveyor to give the material a high-pressure blast before entering the screen box. We also installed an extra water outlet for washing everything down after a day of screening which would be very useful for clean up. Underneath the screen box, we manufactured a bespoke catch box that was rubber lined which assisted in the ease of materials passing through and exiting while also reducing wear and noise. The lining made the catch box fully sealed so no gold would get lost and no water leaking would occur in the process. We also had to make sure there were no catch points or ‘corners’ in the catch box that would hold up the fine material exiting out through the outlet. There was an oversize 10″ outlet fitted at the lowest point of the catch box that could take the heavy flow of fine material falling down through the screen that contained the gold. From there it would get transferred onto the sluice box where the gold would get caught and the water could escape. We had a large inspection hole installed on the underside of the catch box so for access to wash everything down or to carry out any maintenance that may be required in the future. The catch box and all modifications were designed so that the full screening plant could be transported and shipped without any dismantling. With everything in place, the new modified X3 rinsing plant was then loaded and shipped to the United States by 40-foot container and later transported to the site by truck, where it was set up and ready to run some dirt. The plant commenced work in July 2020 for its first season after restrictions from the COVID-19 pandemic eased.
