1. Brief introduction to jet suction dredger
This is our smallest sand suction dredger, which 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. One person is sufficient for the operation of the whole dredger.
2. Working principle of the small jet suction sand gold dredger
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 suitable gold separation units according the customer's ewquirements and the local mining condition, such as the jig, the centrifuge, the pulsating sluice box,etc.
