The Marlin Class underwater pump mining dredge manufactured by DSC Dredge LLC is designed to meet the needs of deep mining and aggregate deposits by providing a more efficient tool for material excavation. Every Marlin Class dredge is specifically designed to handle a particular deposit — from sand and gravel to industrial minerals — to ensure maximum efficiency. Deep digging capability is made possible by the use of an underwater pump system with a high torque cutter drive assembly to complement the rigorous demands of the deep mining industry. Digging depths range from 35 ft. (10 m) to more than 200 ft. (61 m). Discharge sizes range from 8 in. (20 cm) to more than 24 in. (61 cm) to allow for a wide range of production and flow conditions to match specific mining operations.
DSC Marlin Class dredges are available in either a diesel or electric-powered model to meet the customer’s specific needs. Drive systems include a Caterpillar ACERT diesel engine with inline direct marine style transmission for dredge pump reduction, or TEFC electric motor, variable frequency AC dredge pump motor drive and double helical gear reducer for dredge pump reduction. All models feature a PLC operating system, magnetic flow meter, electro-proportional hydraulic circuits, high-capacity service water system, maximizer suction dilution valves and a 3-wire mooring system. These performance features offer deep water dredging capabilities combined with a wide array of suction and discharge sizes to maximize operating efficiencies for every customer’s operation.
