Product DescriptionProduct DescriptionWhat is Sand and Gold Dredging Machine-Bucket Chain Dredger?Type: This is kind of bucket chain sand dredger. Structure: The hull adopts assembled modular box-type structure.Design: The operation mode of the whole dredger is designed according to the geographical conditions provided by the customer, and it is equipped with the operation room, operation platform, generator set, dredging device, sand and stone separation device, tailings conveying device, lifting device, positioning device, etc.Working process: The working process is to drive the bucket through the motor to load the material into the flat screen for the sand and stone separation stage, and the sand and stone within 200mm are screened and then transferred by the chute to the conveyor belt.Optional: According to the previous customer's requirements to add one set 30HP propulsion hanging paddle machine for long distance walk. It is convenient for walking in the smooth water of inland rivers.Features of Bucket Chain Sand Dredger:1) The bucket chain dredger are 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 SpecificationsSand and gold bucket chain dredger technical specificationNo.ModelJUNHANG-LD2001Hull size(L x B x H)28.0 x 6.6x 1.5m2Pontoon length28.0m3Singlepontoon width2.2m4Pontoonheight1.5m5StructureCan bedismantle and re-assembled easily, box structure, lower delivery cost6Displacement126 tons7Equipmentweight95 tons8Dredgingdepth15m9Draught0.7m10Workingcapacity200m3/h11Dredgingmain power75KW12Dieselgenerator180kW13Equippedwith bucket quantity62pcs14Chain quantity124 pcs15Main frame height4m16CustomizedIt can be designed and produced separately according to the requirements of customers17ApplicationChain bucket mining dredger issuitable for river, lake, reservoir and gangue so on. Usebucket gold dredger can get the gold, diamond and iron ore and otherminerals. Outstanding performance can get 85%-98% in recovery percentage.Important Core Component DescriptionHull of the mining machinery:Double of the hull for the whole mining machinery, each hull has 3 parts, transportation way decide its quantity, marine steel plate for the whole hull of mining machinery. And it is sandblasted and painted by 4 layers of marine epoxy paint suitable for saltwater service. The zinc anode can be used to give better anti-corrosion function. All dredgers are made of special marine steel plates, which have been certified by CCS.Digging 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 Power 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. Electrical motor component: Lifting electric motor for underwater big arm, position electric motor for position anchor, digging electric motor, drum screen motor, water supply system electric motor, election mining electric motor, belt conveyer electric motor. 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.Packaging & ShippingFactory shipment and transportationEach 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.How to control the quality of bucket chain dredgers?Testing before shipmentTo 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 waterDredger Test Certificate by CCSRegarding After-sales ServiceWhat kind of dredger service guarantee is provided?1-After-Sales Service-installation and training:*After delivery, we send experienced engineers who will be to guide the installation of dredger and train the operators.* 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.2-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.
