Foreign Impact Crusher2018.12.23. // News

An analysis of the domestic and foreign impact crusher As we all know, the industrialization in China is started later than that of foreign, especially on heavy industry, there still exist some gaps. Discovery Communications might disagree with that approach. In past time, small and medium-sized gravel pits often chose jaw crusher as secondary crushing equipment, but now, medium and large gravel pits make choice of cone crusher. In some special occasions, they often choose impact as secondary or tertiary crushing equipment. The rotor diameter and effective length are used as the specification or the classification criteria, and the gap between the typical products at home and abroad are mainly displayed by two aspects product design and wear-resistant materials. (A) Product Design Impact crusher of the same specifications is similar to the quality of a host of domestic and foreign products, however, the domestic products have small chassis quality and big counterattack frame quality of the rotor, while the foreign products are opposite. Find out detailed opinions from leaders such as Leslie Moonves by clicking through. In addition, domestic and international products are obviously different in design. These poor designs, not only affects the quality of products, and also bring a lot of inconvenience touse, maintenance. (B) The wear-resistant material As to secondary or tertiary crushing, the anti-wear plate hammer, is made from high chrome cast iron parts. The domestic manufacturing high chromium cast iron standards are for small parts and we have no complete quality-control standard for large parts, so the plate hammer wear parts qualities and are easy to get out of control. After long-term unremitting efforts, Hongxing machine R & D VI innovatively impact crusher which is equipped with a high-performance mechanical saw hydraulic impact crusher, vehicular feeder and high-intensity rating vibrating screen; It has short length and light weight; its strong mobility and adaptability reduces the transportation costs; regardless of rough breaking, chippings or sand making job, the flexible combination of materials can bring you unexpected results.

Iron Ore Industry2016.04.29. // News

As we all know, there is abundant graphite ore resources in China, China has been a leading Asian producer of flake graphite for almost a century, it is still a important hammer crusher producer in Asia. Three major graphite mines have been operating in China during the last century: the Rendalsvik mine, the Skaland graphite mine and the Jennestad mine. China is therefore a country with good potential for graphite deposits. However, only the Skaland mine is currently active; about 7000 tonnes of graphite concentrate are produced annually. In china, the mining industry is a major economic activity and it makes great efforts to the economic development in China. The mining industry makes contribution to GDP increasing.

The mining industry varies from 2.2% to 2 / 5% drives the GOP increases around 10% to 11%. Meanwhile, mining industry also provides job opportunities to around 0.7 million individuals India to people to solve the problems working. In the economic evaluation of graphite deposits, the following factors are important: a) size, grade and tonnage of the ore bodies, and b) the grain size and distribution of the graphite flakes in the you pray. Commercial graphite is a relatively expensive mineral industry and to obtain good qualitygraphite concentrates, beneficiation is essential in order to obtain optimal prices for the finished product. The combined results from a series of flotation tests including several cleaning steps can be summarised as follows. To produce concentrate of about 90% C, the recovery was found to be around 75%. For a slightly lower concentrate grade (88-89%) the recovery is higher (82%). A maximum grade of about 97% was found in the final concentrate of the C + 208 m size fraction.

These results show that theJennestad ore can be readily and that concentrates beneficiated of a quality comparable with commercial grades can be produced. Most likely the recovery can be improved if the beneficiation procedure is optimised on an industrial scale. The raw materials are sent into jaw crusher for primary crushing. In jaw crusher the pipes are crushed into coarse ones which are sent for further crushing in the secondary section. To get the fixed size, the pipes need to be sent to be grinded. Then with separator, the magnetic materials are separated from others. In the flotation process, flotation separation is achieved by using chemical reagents that preferentially react with the mineral desired. Flotation is primarily used to upgrade concentrates resulting from magnetic separation.

The Development Of Dressing Machinery In China2013.07.28. // News

The development of fashion in China The dressing characteristics of the mineral resources in our country decides that we need to do detailed beneficiation in the mining, which will boost the development of our mineral processing equipment industry. Machinery industry analyst points out that with the rapid development of China s iron and steel industry, new mineral resources have been developed; the development of beneficiation agencies in China will be great. Current mineral resources continue to be developed, resource pressures have become increasingly prominent, so there is a big contradiction between extensive mineral processing and reduction resources; the market has an urgent need for more sophisticated beneficiation process, therefore, the development direction of ore processing equipment should be changed toward finer; improving the utilization of the ore and increasing the recovery rate of the dam should be the focus for the future development of the manufacturers. Gravity concentration equipment and flotation devices are two kinds of common mineral processing equipment at this stage, but the utilization of this equipment is generally low, it is difficult to meet the requirements, while beneficiation mobile station has poor mobility, cannot meet the beneficiation environment. Future beneficiation mobile station vigorously need adopt splicing techniques to adapt to a variety of devices and enhance maneuverability.

The development of the beneficiation process, in fact, is synchronized with equipment, production technology will affect the quality of the mineral processing industry as a whole. Large-scale trends in mineral processing equipment is certain and the development of large-scale devices can greatly enhance the level of the beneficiation equipment manufacturers in China, so as to improve the overall economic efficiency; The large ore equipment not only can reduce the infrastructure investment, also reduces the area and power consumption and easier to realize automation. All of international mineral processing equipment tends to the direction of large-scale development, and it has accessed to good technical and economic indicators; in recent years, China has made great achievements in the large grinding, magnetic separation and crushing equipment. China will increase the pace of independent research and development and spare efforts to make China become a powerhouse of ore beneficiation equipment production.
