Product DescriptionProduct DescriptionGeneral Description of river mining machinery:River Mining Machinery including Inland Sea Gold Dredger, Iron Powder Extraction Dredger, Tin Ore Dredger, Lithium mining ship, salt mining ship etc. The hull adopts the assembled box structure. Equipped with operating room, operating platform, generator sets, digging devices, sand separation devices, the primary metal extraction device, vibrating selected device, tailings recovery, tailings delivery devices, lifting devices, positioning devices .can be designed according to the working environment.Main Function:River Mining Machinery, is driven by motor to feed the hopper into an extended drum screen. It first mixes sand, stone, and mud, and then enters the sand and stone separation stage. The stones are screened and flow to the side through chute. Fine sand enters the metal extraction chute through sliding sand plate for metal extraction, and the tail sand flows naturally through the chute.Working principle for River Gold Mining Equipment-Jet Suction Dredger:Jet suction sand dredger uses high-pressure jet water column to disperse the ore body, and marine engine controlled by frequency converter to drive the sand suction pump to rotate, creating vacuum at the suction port. The mixed medium is then sucked into the pump and sent to a mineral processing platform equipped with buffering and garbage filtering devices. The filtered fine material (customized according to the customer's pore size) enters the distributor and enters the gold selection equipment through the distributor. The selected concentrate is transported to the destination by conveying pump, and the waste flows through chute to one side of the beneficiation platform. The work platform is equipped with air conditioning and monitoring operation room.Features of Jet Suction Dredger1-Module box structure, easy to dismantle and assemble at working site2-Work capacity could be 8000m3/h3-Dredging depth could be 20 meters4-International famous brand engine, multiple options are available for selection 5-International famous brand China Shijiazhuang pump6-Siemens PLC control system7-Rexroth hydraulic valves and system8-Eaton Vickers hydraulic pump9-Can be operated remotely in the operation room, with good all around visibility10-Full tested in factory before delivery11-Short production time12-Corrosion resistant painting and anti-corrosion zinc block13-Safety and rescue equipmentTechnical SpecificationsRiver mining machinery- jet suction dredger technical specificationModelJUNHANG-JSD450 (18 inch)JUNHANG-JSD500(20 inch)JUNHANG-JSD550(22 inch)JUNHANG-JSD600(24 inch)JUNHANG-JSD650(26 inch)JUNHANG-JSD700(28 inch)Overalllength31.0m33.0m36.0m41.0m43.0m45.0mHull length23.0m27.0m27.0m31.0m38.0m38.0mHull width7.5m8.5m8.5m9.3m9.8m9.8mHull depth2.4m2.4m2.5m2.6m2.8m3.0mWater flow3000m3/h4000m3/h4500m3/h5500m3/h6000m3/h7000m3/hSolid sandcapacity600m3/h800m3/h900m3/h1100m3/h1200m3/h1400m3/hDredgingdepth15m15m16m16m16m17mDischargedistance1500m2000m2000m2000m2000m2200mDraught1.7m1.7m1.7m1.7m2.0m2.0mSuctionDia.500mm550mm600mm650mm700mm750mmDischargeDia.450mm500mm550mm600mm650mm700mmEnginepower1119KW1434KW1798KW2250KW2920KW4000KWWire ropepulling force (lifting winch ) * quantity80KN * 1100KN * 1160KN * 1160KN * 1180KN * 1200KN * 1Wire ropepulling force (traversing winch ) * quantity80KN * 2100KN * 2100KN * 2100KN * 2120KN * 2160KN * 2ApplicationWidely used in sand-excavating fromsea, lake, port, pond, coastal, river dredging, channel maintenance andbroaden, desilting, reclamation for channels and land, port deepening and constructionetc.Important Core Component DescriptionPower of mining machinery:Normally the power from the generator sets, if the customers has the rich electric power can use the outer electric power into the mining machinery. Classification system: Scrubber, drum screen, support, guiding groove, tailing belt conveyerMining collection system:According to the customers request to choose the election mining equipment, agitation chute, fixed gold carpet chute, jigger machinery, centrifuge equipment, gold shaking table so on.Packaging & ShippingFactory shipment and transportationPort dredger loading, transported by bulk carriersEach dredger is detachable structure to facilitate truck transportation on land. Depending on the size, some models of dredgers can be disassembled and transported through containers, some models can be disassembled and transported through bulk carriers. Simple disassembly and fast installation.Each dredger is detachable structure to facilitate transportation on the sea and land.Quality GuaranteeHow to control the quality of jet suction dredgers?Testing before shipment in testing poolTo ensure the good performance and safety, each ship must undergo complete test before leaving the factory, and it is tested like the machine working in the customer's working site. There will be test records during the testing process of dredging performance and safety. After testing, the dredger is sent to the customer's work site for installation and can be directly put into use. Usually, the customer can supervise on site during the dredger testing period. Including: -Condition of electricity connection-Operation conditions of hydraulic system-Engines running and power capacity-Mechanical dredging work-Dredging pump rotates at different speed with fresh waterHow to find and select the river mineral processing equipment?As mineral processing experts, we know what you need to mine efficiently and effectively from start to gold ingot. Recommend suitable geological conditions with abundant gold bearing materialsRegarding After-sales ServiceWhat kind of dredger service guarantee is provided?After-Sales Service-installation, commissioning and training:*After delivery, we send experienced engineers who will be to guide the installation of dredger and train the operators.*Dredger will be tested for running 24 hours after the complete installation. Dredger test includes:Operation of the sand /mud dredging, Hydraulic and electrical system operating, Running of the dredger's outfitting equipment* Our engineers will provide technical training on dredger for customers' workers, how to operate the dredger and daily maintain the dredger until the workers learn it.
