subject: Shougang To Help The New Vertical Crusher Aggregate Recycling Of Tailings [print this page] Product beneficiation operations Separated, one of which was the lowest useful to target some components called tailings. In the current technical and economic conditions, have not further sorting. But with the production of scientific and technological development, may also be useful to target components of a further economic value of recycling. Is not completely useless waste tailings often contain components can be used for other purposes, can utilization. Waste-free emission, is full of mineral resources use and protection of ecological environment.
Large concrete structure application consumes a lot of natural sand and gravel resources. Accounting for more than 70% of concrete volume to be mountains of Aggregates mining, dredging of the River, construction sand and gravel each year from about 50 million tons. Case Study of Beijing, every year 64 million tons used for construction sand and gravel should, of which only used in commercial concrete, sand demand shall be 14 million tons in 2002. Beijing municipal government to control air pollution, improve the environment, Beijing has been gradually shutting down the entire sector of natural gravel pits. Building opened in 2003 resumed in Beijing as much as 100 million square meters area and seek alternative resources imminent.
Shougang Mining Company located in Qian'an County, Hebei Province, because of the iron ore grade is not high, so the following process: Mining stripping rock (waste rock) broken magnetic separation (magnetic pulley abandoned gravel) Ground Magnetic (waste tailings) Magnetic Ground (disused tailings) concentrate powder. Waste rock, covers an area of abandoned gravel pile magnetic pulley, has accumulated about 1 billion tons annually by abandoned waste rock has magnetic pulley to continue to discharge gravel to 1.34 million tons. Second of finely ground waste (tailings) mixed with water storage dam to send reactor has been accumulated 275 million tons, 7 million tons per year at present rate continues to discharge. At present, the tailings have caused a lot of land, pollution of the environment. Liming Heavy Industry
new vertical Crusher Use of artificial sand tailings processing, according to the actual situation, Dawn Heavy Industries launched the mobile crushing plant for the processing of Aggregate system with excellent performance, high reliability, length of the short, small footprint, light weight, mobile strong, reduce materials transportation cost, adaptability, combined flexible, easy to transport, assemble a short time, operation and maintenance of safe, simple and meet the strict Environmental protection Standard features and advantages. Its good performance and mobility, seemed tailor-made for the highway project. Liming Heavy Industry mobile crushing mechanism to produce the fineness modulus of sand, stone powder, gravel gradation, pin sheet content, diameter and other parameters of ultra-Johnson index can meet the Zhongxian highway bridges, tunnels, road projects are the materials required to produce finished products meet the specifications of Aggregates, we can see, of Aggregate in road engineering is completely feasible and promising.
5X Series New Dawn Heavy vertical crusher is the latest technology imported from Germany, while a number of independent patent rights of the latest generation of products, 5X series of new professional broken vertical crusher is the perfect combination of technology and machinery manufacturing model is New technology, new technology a reality. 5X series of new vertical crusher not only for highway, railway, high building, municipal works, construction of hydroelectric dams, ports, Concrete mixing plant Provide the highest quality aggregates such as gravel, sand indisputably become the plastic surgery industry and the stone's core equipment; and increasingly crushing metal ore, quartz sand, slag processing and other fields mainstream equipment. 5X series high efficiency centrifugal impact type sand making machine is a worldwide recognized brand new high crushing machine. 5X Series New Vertical crusher is widely used in various metal and nonmetal mines, cement, refractories, abrasives, glass materials, construction aggregate, sand, Metallurgy And other industries. Applicable in a variety of different hardness crushing ore and rock, such as iron ore, nonferrous metal ores, diamond, bauxite, quartz sand, corundum, perlite, basalt, high hardness materials in petty jobs.
