The average contact stress of the medium in the super-speed ball mill is much larger than that of the conventional ball mill, and the average contact stress increases as the number of revolutions increases. The average contact stress represents the average of the collision force between the medium and the medium and between the medium and the cylinder. The larger the value, the greater the impact force on the ore in the mill and the higher the grinding efficiency. In recent years, the application range of ball mills has become wider and wider, and the research on mills has become more and more comprehensive. Especially for the research of new products--super-speed mills, it has attracted the attention of mining machinery manufacturing industry. After China's ball mills Experts' research and experimental analysis have drawn the following conclusions on the production of mills: 1. The production capacity of super-speed ball mill is improved. Under the action of the guiding mechanism, most of the steel balls fall in the bottom mining area, and the higher the speed of the ball mill, the faster the grinding medium moves, between the steel ball and the steel ball, between the steel ball and the cylinder. The greater the impact force, the greater the capacity of the ball mill per unit volume. 2. Due to the decrease in the ball loading rate of the super-speed ball mill, the loss of the steel ball and the lining plate will be correspondingly reduced; and as the rotational speed increases, a steel ball will adhere to the surface of the cylinder, which can be used for the lining It will play a certain protective role, and will also reduce the loss of the mill liner, which will play a role in extending the service life of the equipment and ensuring the production quality.
