As we all know, mineral resources is a non-renewable resources, the formation process to go through thousands of years of geological changes, reserves are very limited, the new ultra-fine milling machine research and development can integrate a variety of ore resources to improve its comprehensive utilization rate, The limited value of the resource is maximized. Some of the mineral resources in the crust, some buried in the surface, and some are exposed to the surface. As the demand for economic development in the early years, all parts of the country in the development and utilization of mineral resources, in the face of declining mineral resources, a lot of resources have been frequent mining exhausted crisis, from the long-term considerations, but also for future generations to its mining Use must be controlled, reasonable and efficient utilization rate is currently the most problem to be solved.
With the development of science and technology, on the use of mineral resources, we have developed a variety of processing methods, in which the deep processing of ore is to improve the utilization of the most common method. In the case of coal, the finer fineness, the greater the air contact area, the more fully combusted, the same weight of coal and pulverized coal combustion heat can be very different, and coal combustion is not sufficient, high carbon dioxide production, but also with solid Waste generated, so the finer fineness of materials, the more efficient use of the more efficient.
In addition, in addition to the use of mineral resources to consider the value of their own, the waste of resources is one of the more common problems, more common is the tailings and other resources, in fact, although the tailings of mineral quality than ore, but the value is still large Such as limestone, iron ore, etc., by the grinding machine used in the construction industry after grinding, concrete raw materials, cement ingredients can be a variety of mineral tailings by grinding deep processing in the construction industry after a lot of applications.
Each use of mineral resources can often be used to find new resources to replace, in industrial production will be accompanied by solid waste generated, such as slag, coal gangue, etc. Although this is solid waste but if used properly, to be broken grinding, Alternative to the use of many raw materials, mainly used for deep processing equipment crusher, sand making machine and milling machine, the use of more than the mill, Raymond Mill, the European version of the mill, vertical milling Machine, ring roller grinding and so on. Can be applied to road subgrade stones, pit fillers, concrete aggregate, cement and other industries.
