Mineral resources utilization production process
At present, China has discovered by 168 kinds of mineral resources, a variety of mineral resources for human life needs to provide raw materials, all kinds of mineral types of mining methods and production modes are very different, but there are generally similar, such as ore minerals need to go through the blasting, digging, conveying, crushing, grinding, and other processing procedures, today we crushing and grinding as the focus of the processing of mineral resources to understand the next.
Each mineral resource due to its own qualifications, different areas of application, the mining process must also be strictly in accordance with the most suitable way to carry out, in accordance with the differences in processing methods, we come to the classification of ore resources:
1. Iron ore, aluminum ore, gold ore, copper ore and other metal ores production link more than the use of various types of crushing equipment pre-processing, and then the use of ball mills for grinding to facilitate further processing and use, where the ball mill is the key to cause can be summed up as a variety of metal elements based on the ore grinding links need to be used in the ball mill for grinding ore dressing, to facilitate the removal of impurities, beneficiation process.
2. Barite, bentonite, marble, limestone and other non-metallic ores and non-flammable and explosive class ore processing, according to its hardness to choose, for example, marble and other hardness materials can choose the jaw crusher, cone crusher the most first and second level crushing equipment, and then equipped with Raymond mill, high-pressure grinding mill, etc. as a grinding powder processing equipment, limestone and other low hardness of ores can be selected from the impact crusher, hammer crusher and other crushing machines, grinding mill as above, such equipment can be used in the grinding process. Grinding mill as above, such equipment as long as the hardness is suitable for all, but the specific also need to be determined according to the actual application, for example, limestone as stone only need to be equipped with jawbreaker, impact breakers can be, such as the need for further processing need to be equipped with high efficiency fine crusher or sand maker, need to be equipped with a powder mill to help, always for a variety of different applications by the use of the mining equipment to choose from.
3. There is also a class of flammable and explosive, strong acid and alkali type minerals, their processing equipment selection should be extra careful, such as coal grinding requires professional anti-explosive and anti-flammable milling machine, strong acid and alkali type of processing equipment to complete the corresponding material, otherwise not only the production is impeded, but also cause accidents resulting in greater losses.
