| Question: | The current our country in the southern region of coal mine mechanization level is relatively low, but look on the whole, large fully mechanized mining machinery equipment will be more widely used. For example, jaw crusher, stone production line, Ball mill and other mining machinery technology development and promotion, will promote China's coal mine enterprise modernization level rise ceaselessly, and constantly improve and strengthen production safety.
Example proves, use a segment or two segments of grinding flowsheet, using one or two stage grinding process, can be economically put ore grinding to selecting the required particle size, without having to use more grinding section number, more than two segments are usually due to stage and other selected requirements dictate.Grinding segments according to the ore dressing plant scale, are required for the final product fineness and ore properties and other factors to conduct a comprehensive technical and economic comparison, to determine. Apparently, some a few more, is also more complex.
Because the overflow type ball mill has the advantages of simple structure, management and maintenance are convenient, low price, used for fine grinding ratio lattice type, so the use of the plant is much also, can think, when in need of grinding to48-65about uniform coarse product, lattice type is better, when to wear to the 150-200to fine products yes, to use the overflow type, however, this conclusion has yet to be further confirmed by production practice.
In the national policy and the encouragement, China mining industry development is very smooth, and extended to foreign countries, have to say this is a pleasant surprise, all the time since, coal-based energy structure of China determines in large coal mine construction train of thought, in the country are strongly encouraged to energy saving and environmental protection at the same time, coal mine was built, along with coal increase, all kinds of mining machinery also rise, mining machinery and play an important role!
