Gold Trommel Screen
2021-01-13
The mining trommel screen is to filter out the big stones in the original ore and wash away the mud in the original ore. We offer a variety of models, including mini trommel screen that can be operated by one person for small-scale mines and heavy-duty washing plant for big-scale mines. We have passed ISO and CE international certification, safety is guaranteed.
Virbrating screen
2021-01-13
The vibrating screens are mainly used in coal dressing, metallurgy, mine, power station, water conservancy project, building industry, light industry and chemical industry etc They are efficient screening machines for the classification of bulk material such as coal, minerals, coke etc
Centrifugal Concentrator
2021-01-13
The Gold Concentration Separator is a new type of gravity concentration equipment for concentrating gold and other high density minerals. The centrifugal concentrator gets many competitive advantages compared with other concentration machines which create high returns for the investors. The Gold Concentration Separator, which is also called centrifugal concentrator is usually used for roughing separation during the gold separation flowchart to recover most of the useful minerals and get rid of most of the barren rocks.
Gold Mining Equipment Gold Sluice Box Vibrating Chute
2021-01-13
Vibrating chutes  of separation processing has combined the working principle of common chute to jigger. In the function of grid bar, slurry formed nest and pulse flow, then heavy gold and other mineral will be at the bottom layer. Water flow is very small and concentration is heavy. In this part, lighter and fine mineral will be at the layer through the gap, to be sand layer alike.   Inefficiency of common chute is not continuous discharge. So long time working leads to harden and sinking layer, not good for further selection. Jigger needs water to loose the raw material in the gold bed. While agitating chute is workable on both problems of common chute and jigger. It agitates the rubber floor, and no hardens phenomenon. And at the same time, all the heavy gold will be sinker in the rubber floor; natural gold will be in the layer for recycle.
Jigger
2021-01-13
Jigger is an effective and energy saving gravity separation device that has found a wide application in recovery for various kinds of minerals. Unlike the traditional jigging machine, This jig machine produces speedy upward water flow and slow downward flow, so the bed layer is elevated integrally and settled fully with a long effective loose time. As a result, the jig machine has extremely good performance for recovery of gold and diamond.
Mini Gold Dredge
2021-01-13
Mini gold dredger with a gold chute for high recovery rate, powered by a famous engine with pump, float is made up of high strength and light weight plastic. There are advantages that small in size, easy to transportation , it is widely used for working of gold mining in mini river channel.
Dry Washer

Dry Washer for Gold Mining
Sluice Box
2021-01-13
This newly released Gold Sluice Box is a "traditional style and size" high banker, but it packs an AMAZING performance level exceeding most on the market today . Having TOTAL confidence in your equipment is one key factor for mining and prospecting. Moving a LOT MORE DIRT is the next. The New machine provides both. Easily handled and set up with only one or two people, the Real Mining Gold Sluice Box can easily run 150 - 200 buckets of TOTALLY unclassified material an hour, and still maintain extremely high recovery rates, even on very fine gold, remember, the only way to. get more gold is to MOVE MORE DIRT.
Furance
2021-01-13
The power adopts the solid-state IGBT frequency converter module technology from Siemens, after the induction heating equipment outputs the strong frequency current, it can create a strong magnetic field by the induction coils. Under the action of the magnetic field, it can form a vortex current on the surface of the heated work piece, which makes it heat quickly.

Export Country: Uganda

2021-01-12

Dredger Model: HD-CSD250 Export Country: Uganda Year Of Built: 2016 Application: Dredging the lake Water flow: 1200 m3/h Dredging depth : 8 m Discharge distance: 800 m Victoria Lake is the biggest river in Africa and second fresh lake in the world, as years goes by, there are lots of sand deposit, so need to be dredged, the clients are from South America, after several comparison, they chosen Keda due to the high performance and cost ratio of the dredger, within 3 months, they already benificated from their decision.

Export Country: Congo

2021-01-12

Dredger Model: HD-CSD150 Export Country: Congo Year Of Built: 2017 Application: Dredging sand from local river Water flow: 500 m3/h Dredging depth : 10 m Discharge distance: 500 m

Export Country: Bangladesh

2021-01-12

Dredger Model: HD-CSD450 Export Country: Bangladesh Year Of Built: 2015 Application: Dredging port Water flow: 3500 m3/h Dredging depth : 15 m Discharge distance: 1500 m In Bangladesh, their local maritime facilities is inadequate. In Chittagong, the problem is the current maximum draft depth of the port is only 9.2 meters, absolutely is not deep enough for most modern container ships. So it needs to transport all goods from the large Marine ships by small boat. Mongla port also has same issue. Due to this situation, we recommended the most appropriate dredger for them: the water flow is 3500m³/h cutter suction dredger. with it, our customer successfully completed the dredging engineering project in three months.
