According to the data of the
ball mill, the stress distribution of the impact point of the grinding ball is that the impact point directly bears the compressive stress, and the tensile stress is borne on the equator corresponding to the impact point. The tensile stress causes the grinding ball to break. The lower layer of the impact point is shear stress. Shear stress causes plastic deformation and dislocation movement, and produces dislocation accumulation, which will cause spalling to a certain extent. It is widely used in
metallurgy, chemical industry, cement, ceramics and construction. Before the installation of the
ball mill, the electric power, medicine, and defense industries must check and accept the equipment foundation. The surface condition, shape size, elevation, vertical and horizontal centerline of the equipment foundation, especially the spacing and plumbness of the embedded anchor bolts, should be retested and tested. To make precise adjustments, especially in the beneficiation sector in the metallurgical industry, grinding operations have a very important position. Such mills are generally long barrel mills with larger diameters. On the one hand, it uses large ore as the feed material and has the characteristics of a semi-automatic mill. On the other hand, the ball volume is as much as 25%-40% of the volume. It has the characteristics of a ball mill. The ball mill and the beneficiation
ball mill play an important role in the gold dressing plant.
The
ball mill is based on the premise of participating in the full mixing of the reaction materials. For the physical change processes such as heating, cooling, liquid extraction, and gas absorption, the power is transmitted from the motor to the cylinder, thereby driving the cylinder to rotate. The ball mill system uses a grease system to ensure lubrication, and the large and small gears are sealed in the gear shield to prevent external dust particles from wearing the gear wheels. The input load of the large ring gear of the gear-driven ball mill is very large, which has a significant impact on the structure of the ball mill trotters. Quartz sand ball mills often need to use agitating operation to get good results. Stirring equipment is used as a reactor in many occasions. The reason why the application range of mixing equipment is so wide is that the processing capacity of the
ball mill and the particle size after grinding have a significant impact on the efficiency of subsequent operations and the technical and economic indicators of the overall production process.
