Placer Gold Washing Plant is a kind of combined gold mining machine , designed especially for placer gold mine which is contained in the raw material, includes sieving, separating through trammel, sluice and extraction gold progress. It is with wheel type chassis, can be driven by vehicles and move easily.Using a gold wash plant, exposed gold bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold bearing gravel is then fed into the wash plant by a front end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate.

Material is loaded into the plant feed hopper through a static scalping grizzly with 75 mm bar spacing. Oversize is to be periodically removed manually from the grizzly. Undersize feed material is washed into the scrubber feed chute by water jets.
