1. Brief introduction to the sand gold jet suction dredger
The sand gold jet suction dredger is mainly used for sand dredging project in the river, the lake, the reservoir and the channels. Although it is small, it is very efficient .It is easy to operate.
2. Working principle
There is a suction pipe in the front of the dredger. The sand and the gravel on the bottom of the river is stirred up by the water jet prior to being sucked up by the suction pump. Some other manufacturers use air compressor to inject air to the river bottom, which is much less efficient than the water injection according to the feedback from the customers.
The dredger is equipped with suitable gold separation units acoording to the customer's requirement and the specific local mining condition, such as the jig,the centrifuge, the pulsating sluice box,the shaking table, etc.
