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.

Cosmological observations show that dark energy accounts for about 3/4 of the total density of the universe, and it has strange properties that drive the universe to expand. However, the nature of dark energy is still an unsolved mystery. By observing the radiation with a wavelength of 21 centimeters produced by hydrogen atoms, the large-scale structure of the universe can be accurately measured, and then the cosmology measurement can be performed through the baryon sonosonic oscillation characteristics, providing observation clues for studying the dark energy problem. However, compared to other radiation produced by celestial bodies such as the Milky Way, the 21-cm signal is quite weak, so observing the 21-cm radiation at the cosmological scale has always been an unresolved major problem in radio astronomy.
The key technology of “dark energy radio detection†is based on the scientific goal of observing dark energy with 21 cm signal detection, breaking through large-scale radio antenna arrays and calibration methods, long-range mass data collection and transmission, weak signal extraction and certification, etc. The key technology is to build two radio telescope test array systems in Xinjiang. The array consists of three sets of parabolic cylindrical radio telescopes measuring 40 meters long from north to south and 15 meters wide from east to west, and sixteen-meter dish radio telescopes with a diameter of 16 meters. It is currently the most astronomical radio interference array with the largest number of interfering units in the country, and it is also the world’s second-built dark energy radio detection experimental project.
The establishment of the array system laid the foundation for the exploration experiments such as dark energy, rapid radio storms, and gravitational wave electromagnetic counterparts. At the same time, research on the identification and extraction of very weak signals, and the exchange and processing of massive data also laid a good foundation for China’s full participation in and leading the scientific research of the world's largest radio telescope array square kilometer array (SKA).

The key technology of dark energy radio detection has passed the test
[China Instrument Network Instrument R&D] Recently, China's first dark energy detection project, the 12th Five-Year National 863 Program "Dark Energy Radio Detection Key Technology" project successfully passed technical acceptance and began formal observation, and is expected to obtain international astronomy during the 13th Five-Year Plan period. Breakthrough observations.
