The new cone crusher diabase turned Higher raw materials

      time for the large ball mill Ball Size Xingbang Heavy Manufacturing Co., Ltd. to do a little analysis, to allow more dressing understand why lie, the ball mill in order to scientifically and reasonably determine the rough mill ball diameter,Rotary Kiln to first analyze the reasons of the crude mill ball size is too large.Theoretical aspects of the ball mill ball size is too large,brick making machineHammer crusher but also practical and human fars, as follows: 1, the measurement error of the technical aspects: ball diameter to determine the error of the method, mill diameter is much larger than the test under the conditions of industrial production Room mill, large diameter steel ball thrown high, broken high energy density, does not consider the impact of this far also contributed to the ball diameter is too large one of the reasons.2, the test of theoretical knowledge: the lack of mature theoretical guidance.Grinding is one of the most complex operations in the influencing factors in the beneficiation process, therefore from theory to solve this problem is very difficult, although the modern solid mechanics has been from the theoretically calculated lattice between the combination of, and defects in solids impact study, but still unable to resolve the rock and mineral breaking strength calculation on a variety of ore minerals and gangue messy combination of the destructive power of computing is powerless.The strength of the rock and mineral only with the engineering survey to determine, even in the case of known rock and mineral intensity, force the ball in a certain grinding concentration in the pulp by hard to quantify, not to mention there Ball liner shape, mill rate factors on the influence of ball size and impossible to quantify, difficult to determine theoretically, only with the empirical parameters to express.Therefore, the modern theory of grinding can not find the pure theory of the mill ball size formula.So far, most mill ball size formula for the empirical formula, rarely semi-theoretical formula.Empirical formula from the experience of a range of summary may be suitable for a few selected plant grinding actual, but limited the scope of application, the calculation accuracy of the results is also influenced by experience.And most of the empirical formula considering only one or two fars, one or two fars alone to determine the intricacies of the grinding process, is obviously not accurate.

   The same empirical formula is slightly different parameter selection,cone crusherit may lead to a few millimeters or even tens of millimeters error, so that the ball size to determine the difficulty.Foreign empirical formula may not be suitable for China, the country was also suggested that the empirical formula, but with much the same abroad.3, lack of experience: empirical data error.Many concentrator for the save, alicey599 but also recognize the role played by the ball size in the rough grinding ore lack of mill ball direct reference to experience the ball diameter listed in the book.4, the Chinese national conditions and reasons: China's national conditions and habits.Since the sixties and seventies, foreign large-scale mill phenomenon is very prominent, which is certainly related with the level of China's machinery manufacturing, is also not fully aware of the advantages of large-scale mill.Mill small diameter, low potential energy ball mill, we must increase the weight of the ball that is,[rock crusher:http://www.xb-machine.com] raising the ball diameter to compensate for the potential lack of ball diameter should be increased to the number of specific to each mill exactly how much of the ball diameter is appropriate, but not a scientific argument. But to return to the production management of the above, the production management system is not strict also cause one of the reasons that the ball diameter is too large.Operator out of convenience, not the implementation of the mill and ball system, only the addition of a large ball mill ball charge an average particle size gradually increased, close to the diameter of the large ball; management is not strict, the grinding process bloating phenomenon of the mill, grinding grain size failed, do not make a detailed investigation, that any simply boils down to lack of a large ball mill, so to increase the proportion of additional large ball, which is of coarse grinding ball mill ball diameter is too large important reasons.
