18 Inch Hydraulic Jet Suction Sand Dredger for Sale in Malaysia

product description

Jet Suction Dredger is an engineering vessel that collects underwater sand and gravel by combining high-pressure jet and negative pressure suction. It has the functions of excavation, transportation and screening and is widely used in sand mining, dredging, mineral sand extraction and other fields.

Core working principle
High-pressure jet system:
The ship-borne diesel engine drives the high-pressure water pump, which sprays high-speed water through the nozzle

Negative pressure suction system:
The local low-pressure area caused by the jet + the centrifugal mud pump work together to suck the sand-water mixture through the sand suction pipe

product parameters

Shooting faucet
Material: Usually made of strong and wear-resistant metal materials, such as cast iron, stainless steel, etc., to resist the erosion and wear of water flow and mud and ensure long-term stable operation.

Shape: Generally a circular or oval tubular structure, with a sand suction port at the front end and a sand suction pipe at the rear end. Some shooting and suction faucets will also be designed to be bendable or retractable according to actual needs to adapt to different working environments and angle requirements.

Counterweight: In order to ensure the stability and verticality of the shooting and suction faucet underwater, counterweight blocks are usually installed at or around its bottom so that the sand suction port can be better close to the bottom mud layer and improve the sand suction efficiency
