The jet suction sand dredger is a common type of sand dredger, which is used in many river courses for construction. When the equipment is working, our sand suction head and rubber hose are lowered to the bottom of the water. The water in the river is sprayed onto the bottom sand layer at high speed through the action of a high-pressure water pump. The sand is impacted by the water flow and begins to diffuse and mix with water. The sand mixed with water enters the equipment through our sand suction head under the action of the sand pump, Through the action of a pump in the cabin, the sand is then discharged to the shore through a conveying pipeline.
