QINGDAO HEAD DREDGING HEAVY INDUSTRY CO.,LTD.
Gold Trommel Screen
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.
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
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.
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 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
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.
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.
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.
