It is intended for washing and enrichment of gold-bearing sand at buldoser development of productive layers of sand of loose valunisty fields.
It is used as the samostoyateldny equipment, and in a complex with the skrubberny device as the qualifier.
Lamellar hydromechanical roar of GGM-3 - the bathtub welded from thick-walled material in which buldoser skating rinks are located leans on them the cart bearing automobile wheels. By means of a hydraulic cylinder the cart makes back and forth motions. The lamellar cloth so is laid on wheels that it freely sags between wheels. Both ends of a cloth are fixed on face walls of a bathtub. At the movement of the cart the lamellar cloth creates effect of "the running wave". As a result, the sand given on it by the bulldozer or a loader are exposed to a tedding and a grokhocheniye at an intensive irrigation water from the sprinkler established over a bathroom. Plates of a cloth are established with a gap among themselves, equal 30, 40 or 50 mm, the size of a gap determines the size of the enriched fraction.
Small width of cracks of a roar (in comparison with 100 mm at a gidrovashgerd) allows to reduce stream speed on locks, to catch more small gold, to reduce a water consumption. The roar has an inclination about 12 degrees. The bathtub leans on sledge. The Efelny fraction unloads through a cross window in the bathtub bottom in a reception tray which sends it to a lock. Tails from a lock spontaneously go to a dump. Nadreshetny material (Galya) under action above the mentioned effect of "the running wave" is dumped from a back end face of a bathtub of a roar from where in process of accumulation is removed the bulldozer in a dump. Switching of the course of the cylinder - automatic.

For the consumers who are outside the Magadan region GGM-3 of a folding design is offered what allows to reduce considerably time for delivery of the equipment, and also it is essential to lower transport expenses due to transportation of the device in 20 and 40 foot containers.
