With the closing of the large number of small metallurgy, small coal mine, small cement enterprise, large new concentrator, large coal and large cement plant were generally built, which means the higher request of of the washing and dressing equipment was raised. The equipment of great processing capacity, high crushing screening efficiency and reliable operation is in urgent need.The commonly used crushing screening equipment include mobile crusher, cone crusher, jaw crusher, impact crusher, vertical impact crusher, vibrating screen, sand washing machine, the feeder and so on. There has been much discussion in the press and here, among other places, on the growing conflict between the growth of crops for food, and those for fuel. One now is starting to enter a time, when the energy cost of mining production may well fall under the same sort of scrutiny.Chinese Mining Machinery industry has started a praiseworthy effort to look at the energy costs of various methods for producing fossil fuels, and it in the past, tried to explain that there are ways to look at getting rock out of the ground that change the energy cost depending on the way in which mining company actually mines the rock – mining it in very small pieces, for example, costs more energy than pulling it out of the ground in big bits. But I think we have to go beyond that and look at the overall process, and consider that there might be alternate ways of mining that change the overall balance of the energy costs. Mining operations must consider many factors in choosing the equipment, and the mining methods that they use since they must plan on getting the most value from the operation, with a minimal cost.feeder machine: http://www.crusher-machine.com/n142.html vibrating screen machine: http://www.china-hxjq.com/n272.html To sum up, Due to the global rapid expansion requirements for iron ore, coal and ore, mining raised new development boom all over the world. The mining industry association predicted that, driving China and India needs expansion, global minerals price rise continuously and thus push the speed of the merger process of mining companies. Those mining machinery companies which hold excellent Research & Development Team and possess advanced technologies can survive forever in the competitive era. The development of high-new equipment requires plentiful functional materials and the application of modern fine crushing technology has become an important symbol of embodying the technology level. For the washing equipment, all the countries are exploring the new way to meet the separating requirement of diversified minerals and different impurities and make the separating equipment developing for high-efficiency and diversification. The high-efficiency concentrator substitutes the common concentrator in some fields and the new filter will develop quickly, such as auto-filter press with extrusion die and the horizontal belt filter.
