River sand dredging machine manufacturer
1. Brief introduction to small sand suction dredger
This is our smallest sand suction dredger. It is mainly used for sand dredging project in river, lake,reservoir or channels. Although it is small, it is very efficient and easy to operate. Even one man could operate it.
2. Working principle of the small sand suction dredger
There is a suction pipe in the front of the dredger. First you need to inject water into the bottom of the river, then the sand will be stirred up, then the suction pipe could suck the sand and small gravels up. Some other manufacturers use air compressor to inject air into the river bottom, but according our customers' feedback, it is much less efficient than the water injection.
