Some of the mineral resources are inside the crust, some are buried beneath the surface, and some are bare. Due to the needs of economic development in the early years, all countries in the world are developing and utilizing mineral resources. In the face of declining mineral resources, many resources are in danger of being exhausted. From a long-term perspective, it is also for the sake of future generations. Utilization must be controlled, and reasonable efficiency and high utilization rate are the most important problems to be solved at present.
First of all, resource utilization has a direct relationship with the fineness of the material. Taking coal as an example, the finer the fineness, the larger the air contact area, and the more adequate the combustion. The heat emitted by the same weight of coal and pulverized coal can be very different, and Incomplete combustion of coal blocks, high carbon dioxide production, and solid waste production, so the finer the material, the more uniform the utilization efficiency will be;
Second, in addition to considering the utilization efficiency of the mineral resources themselves, the waste of resources is also one of the more common problems, especially the random discarding of tailings resources. In fact, although the quality of the mineral products in the tailings is not as good as that of the original ore, the usable value is still great. For example, limestone, iron ore, etc., are applied in the construction industry after being processed by a Raymond mill to make concrete raw materials and cement ingredients. At present, various mineral tailings are used in the construction industry after grinding treatment;
Third, each use of minerals can often be replaced by new resources. In industrial production, solid waste is generated, such as slag, coal gangue, etc. Although such solid wastes are used properly, they are crushed and ground. It can replace many raw materials. Roadbed stones, pit fillings, aggregates in concrete, and Raymond machined into fine powder, the use value is higher.
In the comprehensive utilization of mineral resources, Kunming Jianshi Raymond Mill is specifically reflected in the improvement of the utilization rate of raw ore, the full utilization of tailings and waste, and the solid waste recycling and reuse. The improvement of resource utilization requires continuous innovation in technology Backing up, all kinds of resources on the earth are limited. In order to ensure the rights and lives of future generations, we need reasonable exploitation to make the use of resources more rational.
