Ball mill is generally used in metal mining, chemical industry, building materials and other fields for material grinding and mixing.
Working principle
The ball mill is a commonly used power grinding machine for crushing and mixing materials. The materials are evenly and spirally fed into the first cabin of grinder trough the hollow shaft from the feeding device, in which there is ladder lining plate or ripple lining plate with different size of steel ball. The rotation of cylinder will generate the centrifugal force which will bring the steel ball to a certain height, and drop down to impact and grind the materials. After the coarse grinding in the first cabin, the materials go into the second cabin, in which there is flat lining plate and steel ball. The materials will be further grinded and are discharged from grate.
Application field
Ball mill is widely used in metal mining, chemical industry, building materials and other industries. The following is a specific introduction to its main application areas:
1. Metal mine: Ball mill is mainly used to crush the ore to separate the useful minerals. For example, the ball milling process can effectively separate valuable metal elements, such as gold, silver, and copper, from various metal ores.
2. Chemical industry: Ball mill is mainly used for synthesis, grinding, mixing and other processes. For example, in polymer materials, the ball mill can achieve particle size control and crushing processing.
3. Building materials: Ball mill can crush and mix building materials to prepare high-quality concrete, limestone and other materials. For example, the ball mill is capable of crushing hard materials to the desired size with consistent uniformity and stability during the grinding process.
Usage and technical requirements
The use and technical requirements of ball mills in different fields are not the same. In metal mines, it is necessary to choose different types of ball mills and grinding bodies according to the hardness and particle size of the material, and pay attention to the wear of the grinding bodies and cylinders. In the fields of chemical industry and building materials, it is necessary to pay attention to the optimization of the process parameters and production capacity of the ball mill to achieve better industrial production benefits.
Ball mill is an important grinding and mixing equipment, mainly used in metal mining, chemical industry, building materials and other fields. In different fields, the use of ball mills and technical requirements are not the same. Through reasonable selection and optimization, the ball mill can achieve better production efficiency.
