Gravitational Gold Concentrator
It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.The device has the following characteristics:
1.Wide application field: the device can regenate various types of activated carbonon by adjusting the angle and rotational speed of furnace pipe.
2.Regeneration activated carbon in the oven retention time 40 minutes, which is applicable to the regeneration levelofall kinds of grain particles, for coal activated carbon also has good regeneration effect.
3.High degree of automation:the device operation achieves automatic control,with man-machine interface+Intelligent instrument control,reduces the operating workers and the labor intensity is low.
4.High recovery rate of Iodine value:basically returned to a new carbon levels above 90%.
5.Low carbon loss:≤1-2%(Coal carbon)But slightly higher than the JHR-O series activated carbon fuel diesel reclamation equipment
6.Easy installation, covers an area slightly larger, but the small space height requirements, large installed power.
Long service life:The core components furnace tube using thick wall (10 mm thick) 1200 ℃ high temperature resistance, corrosion resistant special stainless steel pipe.

As the “black household†in the Chinese automobile industry, the low-speed electric vehicle industry that has been developing for three years has been controversial. The long-awaited admission permits also allow these hundreds of low-speed electric vehicle companies to stay in the throat. Whether China should develop the low-speed electric vehicle industry has always been the focus of debate by various parties. According to He Yong, an expert in the field of new energy vehicles and an academician of the Chinese Academy of Sciences, the development of low-speed electric vehicles is taking the development path of electric vehicles with Chinese characteristics.
Electric vehicles must go the way Reporter: The development of low-speed electric vehicles has been three years, but the identity of low-speed electric vehicles is not yet conclusive, and some people say that low-speed electric cars are not cars, how do you think?
He Wei: What is the low-speed electric car? Certainly counted cars. And it is a product that meets China's national conditions.
For example, in the United States, the biggest contribution of Ford Motor is to popularize cars and make them cheap and easy to use, so the average American has 1.5 people. Japan’s Toyota’s contribution is to find that the compact and reliable car is more in line with the needs of the people, so the Japanese car has gradually occupied the American car market.
China's national conditions are the first to develop electric bicycles, followed by electric motorcycles, electric cars, low-speed electric cars, and finally electric buses. This is the route.
Right of way is the right-to-fund reporter: Why does the permit for a low-speed electric vehicle company fail to respond after all? What does it mean for them that they can't get a license? Is there a deeper reason?
He Wei: There is no way to get on the road without a license, and the issue of road rights is a matter of financial power. Do not give you the right to pass, that is, you do not let you have a market, buy a car that can not be opened, how can there be a market? Therefore, the issue of road rights controversy on the road depends on who is represented by the national policy, who is encouraged, and who is suppressed.
Low-speed electric vehicles can't get licenses. This is actually a problem of market competition. It depends on who is representing the interests of low-speed electric vehicles. National policies should recognize the development path of electric vehicles, and electric tanks may be made from electric bicycles, low-speed electric vehicles, and electric vehicles.
Reporter: Does our electric vehicle industry also face the same problem?
He Wei: Although different, the core experience is similar. The core of this is the irrationality of government support and the entanglement of related interests. The position of some departments in the country is not high at all. It is a representative of the company itself. Different officials represent the interests of different companies. Let me cite an example. As far as power sources are concerned, the development of electric vehicles was a matter of three paths. The first is called hydrogen fuel cell; the second is called hybrid; the third is called electric car. Now that hydrogen fuel cells have been rarely mentioned, hydrogen fuel cells dominated over 10 years ago, so the Ministry of Science and Technology vigorously promoted the transfer of 80% of electric vehicles' money to hydrogen fuel cells. But still did not make it.
We said no at that time, but no one listened. why? Because some big companies in the United States are engaged. In fact, they are not seriously engaged in, they all know hydrogen fuel cells can not make it out, they just do look like, that their businesses also attach great importance to environmental protection. The supporter at that time was Bush, because he was a representative of the interests of oil companies. He wanted to safeguard the interests of oil-burning factories. So look for something that you can't figure out.
The new controversy is whether to make hybrid or pure electric. We have long said that only pure electric play. Hybrid power uses two sets of power: an internal combustion engine, a set of electricity. With two sets of power, investment will inevitably be large without economic benefits. The development of hybrid vehicles is the same as the development of hydrogen fuel cell vehicles.
Why can't slow-speed electric vehicles get a license? The Electric Vehicles Times Network learned that He Yong, an expert in the field of new energy vehicles and an academician of the Chinese Academy of Sciences, called for: “This is essentially a question of market competition. It depends on who is representing the interests of low-speed electric vehicles. National policies should recognize the development path of electric vehicles. Electric tanks may be made from electric bicycles, low-speed electric vehicles, and electric trucks."
