Before we produce the gold dredger, we need know following conditions in your river:

a. F: Working area of gold dredger inland river or Coastal area or Dry land with water source

    A: Gold mining equipment will be designed according to different working places.

b. F: The water depth from water surface to sand if working in water?

     A: Dredging equipment is available for gold mining from lake, river, sea as: 

          1. Bucket chain dredger( Stone percentage is more than 30%);

          2. Cutter suction dredger(Stone percentage is less than 20%);

          3. Jet suction dredger(Stone percentage is less than 10% for fine sand)

c.  F: Sand or mud thickness in river or in hill 

     A:  Sand thickness+water thickness=Dredging depth in water

           Mud thickness+stone thickness=Gold dredging thickness

d. Degree of the sand or mud soft or hard, may be better for pictures and crude ore. 

e.  F:  Clay content? 

      A: Screener is available for clay washing and cleaning the sand 

f. Stone diameter is required between 1cm to 3cm, and it is better to offer the percentage.

g. Stone percentage of diameter 30cm

h. Coarse particle gold or fine particle gold

i. Working capacity per hour

j. Use network electricity or generator
