Product Description
The JULONG-CSD4515 is configured as a customized cutter suction dredger for sand dredging. Its name in the supplier's product listing is 'Customized Cutter Suction Dredger for Sand Dredging,' reflecting that each unit can be tailored to the buyer's site requirements. The advertised dredging capacity is 800 m³/hr, and the maximum dredging depth is 10 m. These two parameters are the primary sizing criteria for dredge pump, cutter power, and hull dimensions.
The cutter suction head loosens compacted sand before the suction pipe takes it up. This method is suited to sand mining, as opposed to free-flowing slurry dredging. The absence of a slot type (Slot Type: No) means the dredger does not use a slotted screen intake; instead, suction is directed through the cutter head and pipe. The cyclone type is hydrocyclone, which indicates a centrifugal separation stage that can dewater or classify sand before discharge.
Drive is by diesel engine, with engine brands listed as Cummins, Weichai, Changchai, or others. This gives buyers flexibility to match engine availability and service networks in their region. The control system is an all-hydraulic system, and the operation system is a PLC control desk. An all-hydraulic arrangement typically drives the cutter, dredge pump, and winches via hydraulic motors and pumps, eliminating direct mechanical drives. The PLC desk centralizes start/stop, speed, and dredging parameter control.
The dredger is specified for work in river, lake, port, canal, and coastal area environments. Transport package is in container or bulk ship, which means the dredger can be shipped as deck cargo or in parts depending on overall dimensions. A one-year warranty period applies. The HS code 8905100000 places the unit in the customs category for dredgers. Production capacity is 100 sets per year, and the price range is US$100,000.00 to US$850,000.00 depending on engine brand, customization, and optional equipment.
Applications
The primary usage declared by the supplier is sand dredging. The JULONG-CSD4515 is intended for extracting sand from riverbeds, lakebeds, port basins, canals, and coastal areas. The work area list includes both inland and nearshore environments, so buyers should evaluate water salinity, wave exposure, and bottom material when specifying pump seals and hull material.
The 800 m³/hr dredging capacity supports medium-volume sand production. At this rate, a continuous operation can move significant sand volume per shift, but actual output depends on soil type, dredging depth, and discharge distance. The 10 m dredging depth suits many river and canal sand deposits, as well as nearshore coastal recovery. For deeper deposits, buyers must confirm whether the ladder and winch system can be extended.
The diesel engine drive and all-hydraulic control make the dredger independent of shore power, which is critical for remote river and lake mining sites. The PLC control desk reduces manual valve operation and can log operating parameters for production monitoring.
Application Scenarios
The JULONG-CSD4515 fits several sand dredging use cases based on its listed work areas and performance parameters.
River sand mining: In river environments, the cutter suction head excavates compacted sand layers, and the suction pipe delivers slurry to the onboard hydrocyclone. The 10 m depth covers most mid-channel sand deposits. Diesel engine operation allows deployment away from grid power, which is common in inland mining areas.
Lake sand extraction: Lakes with sandy bottoms can be dredged for aggregate recovery or environmental restoration. The all-hydraulic system provides precise control of cutter speed and swing rate, while the PLC desk lets the operator adjust parameters for varying lakebed conditions.
Port and canal maintenance dredging: In navigation channels, the dredger can remove accumulated sand to restore design depth. The 800 m³/hr capacity is suited for maintenance campaigns rather than capital dredging of hard rock. Buyers should confirm with the supplier that the cutter tooth configuration matches the sediment type in the specific port or canal.
Coastal area dredging: The work area list includes coastal areas, indicating potential use in nearshore sand recovery, beach nourishment, or harbor entrance dredging. Coastal operations may require additional corrosion protection; this is a customization item to be specified at order.
