Compared with the ball mill, the dry ball mill has the following structural features:
The diameter of the ball mill cylinder is about three times its length. The self-grinding machine relies on the mutual impact of the ore itself to achieve the purpose of crushing the ore. Since the density of the ore is lighter than that of the metal medium, the impact force is also small. Therefore, the diameter of the self-grinding machine must be designed to be larger. At present, the diameter of the self-grinding machine is 7.5m, and the self-grinding machine is 8m diameter. The larger the diameter, the more the investment is saved.
The shortness of the ball mill cylinder is to prevent the ore from being generated in the cylinder. The westward phenomenon has a great influence on the self-grinding, and obviously reduces the grinding effect. The cylinder is short, and the ore and the ore can fully exert the impact crushing ability.
