1. Raw materials feeding by excavator
Raw materials are fed via excavator from the feeding hopper of the mobile trommel screen, there is strong water pressure of pipe equipped in the large hopper
2. Washing and classifying of the raw materials
The raw materials will be washed and classified by the rotation of mobile trommel screen, there is water pipe at one side of the trommel drum or inside. The gold dust will become slurry state and flows to the sluice box. Larger gravels will come to the end of the trommel, and can be sent away by belt conveyor.
3. Collection of rough gold dust
The gold dust is heavier than soil and sands due to the greater specific gravity, which will stay on the PVC mat in the sluice box, while lighter materials will flow away. When the above goes for a certain time, the rough gold dust can be collected in the PVC mat. Thus the process is finished.
Working principle of sluice box
Sluice box, or sluice chute with barriers along the bottom called riffles to trap the heavier gold particles as water washes them and the other material along the box. This method better suits excavation with shovels or similar implements to feed ore into the device. Sluice boxes can be as short as a few feet, or more than ten feet.
