Cutter Suction Dredger(CSD) is the most widely used engineering ship in dredging works and sand production. The rotary cutter head at the inlet of the suction pipe cuts and loosens the sand/mud layer to form sand-water mixture of a certain consistency. The pump uses its centrifugal force to suck the mixture and then transport it to the depository through the discharge pipe. The digging and transporting are progressing at the same time. CSD is of ideal dredging depth, long discharge distance, high efficiency and low cost.

Chain dredge is equipped with a series of bucket chains. The bucket chains move continuously on the bucket bridge driven by the upward guide roller. The buckets dig mud underwater and bring the mud above the water surface.Draw in or draw out the anchor cables forward,backward,leftwards or rightwords to move the hull to corresponding directions to continue the mud dredging work.The dredged mud is first elavated to the top of the bucket tower and then discharged from the mud flowing gutter.
Chain dredge has a strong environmental adaptability.It can dredge sorts of mud and sand except rock.It has a large working capacity.The dredging section has a regular shape.The error is minimal.Chain dredge can be apply to watercourse dredging project as well as port and wharf.

Chain Dredge (chain-bucket dredger) can carry out the procedure of digging, filtering,washing and classifying at the same time and put out qualified clean sand and rock products which are perfect material for construction uses. Diesel Engine or Diesel-Electric Propulsion.Capable of dealing with four kinds of aggregate. Can be equipped with river gravel crusher as well as gold fossicking and iron sand extracting equipments. Capable of progressing second washing.

Yuanhua Gold Dredger can be widely used in watercourse and near shore where contains gold richly. It is of high automation,high efficiency and high gold selecting precision.Easy to operate.Easy to disassemble.It works continuously.

Gold dredger is a mining joint unit of constructing on the engineering punt and floating on the water surface, which generally includes mining, washing, selecting, the tailings abandon and power generation, water supply, power supply, sliding and other equipment.

Gold Dredger is the bucket gold panning ship, the equipment is made up of eleven parts and systems.

After excavating,the raw ores are sent into the first selecting hopper.After filtration, ores with the granularity of more than ±50mm are dumped through the conveyer belt and ores with the granularity of less than ±50mm are transported to the hopper room and then into the beater cylinders evenly. The ores are mixed in the beater cylinder by a hinge teeth and washed by a high-pressure water jet to wash away the clay. Then the ores are sifted by grading sieves(the sieve mesh depends on the actual placer gold granularity).Heavy ores fall down to the automatic wash-dressing machine through the sieve meshes. After automatic wash-dressing,the ores are sent into the precise gold concentration machine(jigger+centrifugal concentrator) to carry on the selecting procedure. At the end, the output products are high purity heavy mineral metal--gold dust , tungsten , tin , red iron , brown iron , manganese , titanium , etc.

Iron ore selecting machine

used to separate iron from sand and stone

The sand , mixed with water, goes through a sieve to screen our gravels, and then falls into the tank with homogenizing board. Diluted and washed by water again, the sand enters into magnetic area on the roller. High grade iron sand is absorbed on the surface of the roller and transported to the washing unit. After washing out the useless sand, the iron sand is transported to selecting unit. The higher grade iron sand will be washed into the collecting tank and the nonmagnetic sand enters into the tailings tank.

Small Self-propelled Sand Dredger

The water jet and rubber hose go down underwater.

The water jet shoots strong water flow into the sand layer to loosen it.

The Sand Pump pumps the sand into the cabin through the hose.

Sand and stones are separated through the sieve.

The propeller moves the ship to the near shore.

The bottom of the cabin opens and dumps the sand near the shore.

A small ship with pump would then suck and dump the sand onto the shore.

Yuanhua Mowing Vessel is used to gather weeds and surface floats in rivers with high efficiency. It is all hydraulic driven, paddle wheel, header, cutting knife . The system is fully hydraulic controlled. The circuit is manually controlled through a multi-way valve. The right and left paddle-propeller are separately controlled by each steering valve and oil motor. which enable both paddles move forward or backward at the same time, or individual forward, or individual inverse, to make the body of the ship move forward and make a turn. the main engine is a single host, which is above the deck.

Yuanhua Slurry pump :

cantilever ,horizontal centrifugal slurry pump , suitable for metallurgy , mining, coal, electric power , building materials, and other industrial departments to transport strong corrosive ,high concentration of slag pulp .this type pump can dual multistage series use

Different model works most efficiently in different environment under different condition
