Cutter Suction Dredger
A cutter head is a mechanical rotating tool that can cut hard soil or rock into pieces. The winch pulls the winch by pulling the winch to make a fan-shaped movement, and the rotating cutter head can enter the water and swing in the soil. It is installed in front of the suction head, and the soil and rock cut into fragments are sent directly to the mud treatment area through the powerful suction of the dredging pump.
For specific types of soil, Leader Dredger will design different cutter head heads. Because different soils have different hardness and different viscosities, the cutter head heads that need to be used will be different.
It should be noted that the cutter teeth need to be replaced, because dredging in hard soil will cause it to wear out.
The cutter suction dredger equipped with propulsion means can carry out long-distance travel and is used flexibly all over the world.
Small and medium-sized cutter suction dredgers can be disassembled and transported on land.
It should be noted that the cutter suction dredger is very sensitive to the rough seas, because the turbulent waves will break the positioning device of the cutter suction dredger, and make the cutter head off the bottom of the water, causing additional losses. Use the three anchor positioning method.
It needs to be equipped with a positioning device during work, which is suitable for the still and slightly wavy river surface, because the positioning device of the cutter suction dredger needs to be inserted into the soil, and the excessive surge will bend the positioning device of the dredger.
Cutter suction dredgers have high productivity and can effectively handle most of the materials.
Material type:
Small and medium-sized cutter suction dredger:
Silt
Clay
Sand
Gravel
Large cutter suction dredger:
Coral
Broken rock
Small hard stones
Cutter suction dredgers can be used in many environments, such as river dredging, channel dredging, port construction and maintenance, and environmental dredging.
When the depth of most working conditions is relatively shallow, discharge distance is relatively close, the preference is INBOARD PUMP CUTTER SUCTION DREDGER
Inboard pump dredger is the most common type of cutter suction dredger, and it is currently the most cost-effective model. Its pump is installed in the engine room. Because the driving structure of the pump is relatively simple, it can save costs. This design is suitable for most waters and is the most common among small and medium dredgers.
When the depth of most working conditions is relatively shallow, discharge distance relatively close, the priority is to choose the SUBMERSIBLE PUMP CUTTER SUCTION DREDGER, that is, the pump is on the ladder.
The pump of the dredger is on the ladder. Compared with inboard pump dredger, the suction port of the pump is closer to the sediment at the bottom of the river, making the pump suction concentration higher. It achieves higher output and higher productivity. Submersible pump dredger has deeper digging depth and higher concentration than Inboard pump dredger.
Because the submersible pump dredger can dig deep to 30m underwater, a larger hull is required. Pumps, drives, and motors all need to be installed on higher-strength ladders and more complex driving methods, resulting in submersible pump dredger cost much higher than Inboard pump dredger.
When the water depth is very deep and the discharge distance is very far, suitable for DUAL PUMP, or even MULTI-PUMP CUTTER SUCTION DREDGER
The Dual Pump Dredger has two pumps, a main pump on the ladder, and another relay pump in the engine room. This design can achieve large digging depth and output and ultra-long distance.
Dual pump dredger is the ideal choice for maximum digging depth and very long discharge distance.
