The medium cutter suction dredger is a multi-functional equipment specially designed for medium-scale dredging and sand mining operations. The core adopts an integrated cutter suction structure, driven by energy-saving diesel power to rotate the cutter for dredging. The high-power mud suction pump sucks the mud and transports it to the designated area through the mud delivery pipe to realize the continuous operation of dredging, mud suction and mud discharge. The equipment has the advantages of moderate volume, stable production capacity, convenient transfer, wear resistance, energy saving, intelligent control and strong adaptability. It not only solves the problem of insufficient production capacity of small equipment, but also avoids the limitations of poor flexibility and high cost of large equipment. It can be adapted to a variety of medium river and shallow water operation scenarios. It can be used for dredging and also matched with gold mining equipment for large-scale placer gold mining. It is a cost-effective core preferred equipment for medium river operations.
