According to incomplete statistics, China's urban and rural housing construction, demolition of old buildings each year of construction waste generated by about 200 million tons per year two billion square meters of new buildings generate waste 100 million to 1.2 million tons, which brought a serious problem : such a huge amount of construction waste, how to treatment?whether environmental protection while in processing?
It is understood that domestic construction widely used means of disposing of waste is simply piled and landfill, which will not only take up a lot of land, polluted urban environment, but also adverse effects on the urban groundwater, to a large extent hindered the healthy development of the city .This is neither environmentally friendly, can not achieve an effective construction waste recycling and utilization.
Environmental protection is our eternal theme of social and economic development in the global environment is deteriorating and growing energy crisis exacerbated the situation, the development of energy-saving environmental protection industry is a community have to face reality, but also to promote sound and rapid economic development after all the road. Now is precisely the height of the global environmental topics addressed during the weather change and energy, environmental protection, low-carbon economy have become issues of concern to the international business continued. An industry source pointed out, energy saving, environmental protection, mining machinery products respond to market risk is the future of medicine.Gold ore flotation process
Gold in the ore were very low, in order to extract the gold ore crushing and grinding need and use pre-enrichment or beneficiation manipulation gold from the ore separation. Gold ore is used in more re-election and flotation, flotation in placer gold production occupies an important position, flotation is widely used rock gold mining beneficiation methods, about 80% of the world of rock gold selected using this method gold mining, mineral processing technology and equipment level has been greatly improved.
According to the survey, about 80% of the rock gold mine with gold by flotation, concentrate output sent to non-ferrous smelter deal more. The cyanidation of gold in the increasing development and enterprise to improve the economic efficiency and reduce transport losses concentrate, the product mix in recent years, great changes have taken place, to take a more local processing (of course, the contradiction between the dressing and smelting and pricing And other issues, forcing the mine in place to handle) to promote greater development flotation process, in gold production plays an important position. Usually both flotation and bulk flotation process. Transformation in recent years, and pharmaceutical process systems to add new progress, flotation recovery has improved markedly.Stone Crusher port terminal construction
Efficient Fine Crusher, also called fine crusher, new fine crusher, also known as third generation Sand maker, fourth generation sand machine. The machine uses a wide range, its performance has reached international advanced level, is the most effective, practical and reliable stone machine, especially for the production of abrasives, cement, quartz sand, grit and other hard, brittle materials The crushing and in the debris, is a highly efficient, energy-saving equipment, sand gravel, crushing machine energy than the traditional 50 percent, is the world's advanced crushing machine equipment.
Widely used in granite, basalt, limestone, river gravel, cement clinker, quartz, iron ore, bauxite and other minerals, fine crusher. Mechanism is also used for artificial sand, highway, railway, water conservancy, airport, construction, cement, metallurgy and other industries producing high-quality stone. Especially for the high hardness of river pebbles when broken, excellent performance, it is also known as river pebbles or river gravel crusher.
