Tailings sand making production line Introduction:
2000 Yifan Machinery successful development of Y650 vertical shaft impact crusher (sand making machine) reached domestic leading level: built first using tailings, using vertical impact crushing mechanism of production lines, and create a mechanism of sand production line of new technology.

Tailings is the metal ore, non-metallic minerals in the mining and processing of the main minerals stripped of surrounding rock, discarded low-grade rocks and process the waste. These tailings are piled up around the mines, occupation of land, damage to surface, soil destruction, biological threat, silted riverbed, water pollution, flying dust and atmospheric pollution. To the country coexistence of various types of tailings 6 billion tons, covering an area of ​​420 hectares, causing great harm. If you take advantage of this resource, and the annual the new emissions Tailings artificial gravel annually can solve 20.4 million tons of construction with gravel, if stacked tailings are utilized, the light of this resource can be 20 years. That solve the tailings environmental problems, to solve the building with gravel resources, kill two birds with one stone.

Tailings to produce artificial sand feasibility analysis report:
1. Tailings artificial sand stone: GB, construction sand GB/T14684-2001 Pebble and the rubble "GB/T14685-2001 above tailings test, due to the artificial gravel particle level with flakiness content, the powder content, mud content of these indicators can adjust by changing equipment and process parameters in the production process and control, no decision on the tailings whether made artificial gravel impact, while the strength harmful substances, robustness, and alkali-aggregate reaction is to determine the tailings whether the system the artificial aggregates the key. The vast majority of tailings made of artificial gravel qualified individual is not suitable for artificial sand tailings can be controlled through the choice of raw materials. Of course, from the other hand also shows, not all tailings can be used for making artificial sand and gravel, should be strengthened in the production of raw materials inspection, in order to protect the quality of the artificial aggregate.

2. tailings artificial sand preparation of concrete

Building rubble has been used for many years, the actual building rubble is artificial stone, therefore, has no need to conduct a study of the application of the tailings artificial stone in the concrete. And the artificial sand due to its particle size distribution, grain shape, and even color and natural sand are obviously different, artificial sand tailings regardless of the preparation of ordinary concrete, concrete, concrete products are feasible, and the amount of cement savings, ease of sexual gratification, various age strength guarantee. Tailings artificial sand preparation of concrete with natural sand concrete prepared than some of its own characteristics (unpublished data), but in terms of general use units, is not difficult to grasp, lies in the ideological emancipation, understanding improve receptive to new things.

Yifan Machinery VI column efficient sand making machine, Yifan Machinery introduction of international advanced technology, a number of independent patent property rights for the mine tailings broken and shaping a new generation of products, set three broken mode mechanisms sand the core equipment in the industry, a new efficient crusher. VI Sand is an impact crusher, sand making equipment, by senior mining machinery manufacturers in China recently put on the market, a product of domestic sand making equipment production field representative, reflects the domestic sand making equipment The manufacturers of the latest technology and the latest production technology, professional crushing a model of the perfect combination of technology and machinery manufacturing.


2000 Yifan Machinery successful development of Y650 vertical impact crusher (sand making machine) reached domestic leading level: built first using tailings, using vertical impact crushing mechanism of production lines, and create a mechanism of sand production of new technology.
