Fluorite tailings are wastes produced after fluorite flotation, containing about 20% of calcium fluoride and the like. If not handled properly, it will cause pollution to water resources and the like. It is estimated that, after years of flotation, Jinhua city and county of fluorite tailings accumulation has reached millions of tons. Only Wuyi has 1.5 million tons of fluorite tailings and 200,000 square meters of concentrated piles. Some of the dumping areas constitute a major hidden danger causing geological disasters.
After two years of trial and error, in June last year, Shenlong Company successfully developed a flotation tailings flotation production line. After processing by the tailings flotation production line of Shenlong Company, the calcium fluoride content in the fluorite tailings decreased from 20% to 1%, and the pollutants in the tailings were basically removed. The waste generated after the flotation of fluorite tailings has also become a good building sand. Shenlong also cooperated with a building materials research institute in Beijing to develop successful ore-free hollow bricks. At present, the production line of non-burning bricks is about to be put into production.
A technological innovation has transformed Wuyi Shenlong Company from a polluting enterprise into a large decontamination household. Tested by Wuyi County Environmental Protection Bureau of Zhejiang Province, Shenlong Company's tailings treatment has reached the relevant standards. Zhou Aima, chairman of Shenlong Company, said: "The company is ready to invest another 10 million yuan to expand the production scale of tailings flotation, and strive to use 10 years to 'eat' all the discarded tens of thousands of tons of fluorite tailings in Jinhua counties and cities. ."
Hook Type Ring Winding Machine
The common functions of Automatic Winding Machine include preset number of turns, automatic stop, positive and negative winding, automatic slot crossing, etc. in actual use, we should pay attention to several points. First, start winding idle and stop winding idle. Start winding idle is the function of slow running after starting the equipment, so as to reduce the impact on tension structure and enameled wire, Generally, it can be set as 1 to 3 turns according to the actual needs. The stop and idle function is that the equipment runs at a slow speed before ending the winding sequence. This function can reduce the impact on the brake and make the equipment finish winding smoothly, especially for the winding process that needs precise positioning. This parameter must be set according to the running speed of the equipment, The parameters should also be adjusted accordingly. Generally, it is 2 to 5 turns, and then the winding direction and the winding direction. These two parameters are respectively the setting of the winding displacement direction and the spindle rotation direction. The winding axis and the spindle of the automatic winding machine are controlled by the controller, and there is a specific linkage relationship. When setting, the displacement direction of the winding axis must be clear, Many users report the equipment alarm during debugging, which is due to the equipment protection caused by the wrong setting. The winding machine has a zero detection point, which is used to position the winding shaft. If the equipment is started from the zero point, the winding shaft must move outward. If the equipment is set to move inward by mistake, it will cause the equipment alarm. The rotation direction of the winding shaft should be determined according to the winding process, All settings should fully consider the needs of winding process.
