Working Principle

Using excavator to feed raw material to the hopper ,then, they flow into double trommel , big stones and pebble can be separated and flow outside of the equipment, mineral aggregate with gold whose diameter is less than 6mm can enter into the beneficiation
sluice through inner trammel screen,there is a fixed and high extraction ratio gold felt sluice in one side of the beneficiation sluice to extract gold particle. The machine is equipped with big flow capacity and big head water pump, can supply high pressure
water for hopper, trammel, the mineral aggregate with gold will flow through the gold felt in the effect of self weight and waterpower ,lighter mud or sand will be washed away and big specific gravity gold is left on the gold felt.
