How many cubic meters can a dredger remove per hour?

The dredging capacity of a dredger is affected by various factors, including its type, dredging depth, and soil conditions. Chain bucket dredgers are highly efficient, reaching hundreds to thousands of cubic meters per hour (e.g., a 21-meter dredger under ideal conditions), while cutter suction dredgers, due to their ease of operation and low cost, are slightly less efficient. Increasing dredging depth reduces efficiency (e.g., deep-water operations require additional energy), and soil hardness directly affects dredging speed (efficiency decreases by more than 50% in hard soil/rock). Taking waterway dredging as an example, cutter suction dredgers can achieve a continuous operating capacity of 300-500 m³/h in soft soil conditions. If paired with a high-powered mud pump (e.g., a conveying capacity of 5000 m³/h), the overall efficiency can be significantly improved.
