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 mining machinery-Bucket Chain Dredger: Chain bucket river mining dredger is used for river gold, diamond, tin and sand iron powder so on. The bucket chain gold dredgers use the buckets, driven by guide wheels on continuous rotation on the bucket bridge, sand, mud and stone so on are digged by the bucket with chain from the water above. Bucket rotates around the underwater dredging wheel, scooping up the solid in the riverbed, then into the separating system. Solids larger than 10 mm will go into the tail-box, tailing discharged to place far away from gold dredger. Less than 10 mm of material from the flow channel into the Gold Sands separation system, based on the difference between the relative density of sand and gold, gold will fall into the bottom since of the high density, sand and other material will float on the surface, and discharged to the tail system by water.Features of Bucket Chain Sand Dredger:1) The bucket chain dredger is designed according to clients specific mining conditions and requirements.2) Dredging depth could be min 5 meters and max 30 meters.3) Processing capacity could be 60m3/h-800m3/h.4) The chain bucket system digs the materials from river/sea bottom, convey it up and feed into the trommel.5) Double sieve trommel screen with bearings and high pressure water spray pipes on both sides for washing, screening and separating.6) Double gold recovery systems to ensure highest recovery rate of gold (up to 98%).7) Water supplying systems with multiple sets of big power submersible slurry pumps, hoses, valves, etc.8) Powering system with famous diesel generator with all batteries, cables and wires.9) Gold refinery plant to make final product of gold bars.10) Easy for installation, operation and maintaining.11) One-Step gold mining solutions from A to Z.Technical SpecificationsGold Mining Machinery bucket chain dredger technical specificationModelJUNFA-LD80JUNHANG-LD120JUNHANG-LD150JUNHANG-LD200JUNHANG-LD300JUNHANG-LD600Hull size(L x B x H)16.0 x 6.0x 1.0m28.0 x 6.6x 1.2m28.0 x 6.6 x 1.3m28.0 x 6.6x 1.5m28.0 x 6.6x 1.8m28.0 x 6.6x 1.8mPontoonlength16.0m28.0m28.0m28.0m28.0m28.0mSinglepontoon width2.0m2.2m2.2m2.2m2.2m2.2mPontoonheight1.0m1.2m1.3m1.5m1.8m1.8mStructureCan bedismantle and re-assembled easily, box structure, lower delivery costDisplacement98 tons98 tons102 tons126 tons150 tons150 tonsEquipmentweight65 tons65 tons72 tons95 tons120 tons120 tonsDredgingdepth7m15m15m15m15m15mDraught0.6m0.6m0.7m0.7m0.8m1.0mWorkingcapacity80m3/h120m3/h150m3/h200m3/h300m3/h600m3/hDredgingmain power18.5KW55KW55KW75KW90KW90KWDieselgenerator100kW150kW180kW180kW200kW300kWCustomizedIt can bedesigned and produced separately according to the requirements of customersImportant Core Component DescriptionDigging system: Underwater five angle wheel, underwater digging big arm, bucket, connection chain big arm gantry, overwater big arm, overwater four angle wheel, main support frame 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 so on.Gold Processing LinePackaging & 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 bucket chain 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 waterLand conditions suitable for using gold mining equipmentHow 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. After-Sales Service-warranty and maintenance:*We provide free warranty and on-site maintenance service for a period of one year after commissioning.*24/7 technical support standby.
