Plaid type ball mills and overflow ball mills are two different types of milling equipment, but their basic construction is similar, and their main difference is that their pneumothies are plaid, while the other has no decent panels. Of course, the lattice plate is a plaid type ball mill. Its main advantage is that the slurry liquid is relatively low, and it is possible to discharge the qualified product in time. Therefore, the minerals with large weight do not concentrate in the ball mill, and there is less. The mine speed is faster and efficient. In addition, the internal storage slurry of the lattice ball mill is small, and it is possible to increase the ball, but it is more convenient to install the ball. When the steel ball falls, the mineral resistance is reduced. Therefore, production efficiency is improved, which is 10 to 25% more than the productivity of the overflow ball mill. However, the plaid ball mill is complicated, and the plaid is easily bad, it is not easy to repair, and the price is higher. The overflow ball mill has no lattice plate. Its mineral mode is from the lower edge of the mine slurry itself over the hollow shaft overflow, but it is discharged to prevent the mole from being discharged with the crude particulate ore, in the hollow shaft The inner surface of the bushing is inlaid. The overflow ball mill makes it easy to manage and repair, but his mine is higher, the slurry is longer in the mill, resulting in low unit volume treatment, so his granularity is uneven, which is easy to produce pulverized. In the process of the application, the grinding particle size is at 48-65 mesh and right, and the grid type ball mill can be selected when the grid type ball mill is selected at 150-200 mesh products.
