The size of ball mill media balls determines the amount of energy carried by the medium to a certain extent, and also relates to the amount of crushing force applied to the material, which ultimately determines the grinding efficiency and the quality characteristics of the product, and affects the power consumption and medium consumption of the device during operation.
Therefore, the size of the media is critical to the ball mill, and the choice of media size and the proper state of media motion have a considerable impact on the grinding process.
When the ball mill media balls is used, it will have an important influence on the material grinding due to the size of the medium. Therefore, workers who need to smash for a long time in the process of operation have done a lot of research on how to accurately determine the size of the medium.
Domestic research experts have concluded that domestic and foreign experiments and production applications have concluded that a new type of ball-milling-column (segment ball) with reasonable shape, size and grading is suitable for improving grinding efficiency and reducing ball consumption. medium.
The ball mill will drive the movement of the medium group during the process of rotation. During the movement, the medium will collide with the adjacent medium and the inner wall of the mill. The collision will determine the movement law of the medium in the mill.
Due to the complexity and unpredictability of the grinding process, it also brings certain difficulties to the research of medium motion. With the application of DEM in the engineering field, this technology has also been gradually applied to the modeling of medium motion in the grinding process.
