Grinding is an important process in material properties and particle size, and is an important requirement for reducing the particle size in the preparation of various industrially used raw materials. The strength coefficient of broken particles is a fundamental parameter that reflects the breaking strength of crushed particles. It is one of the primary parameters in determining the practical application value of materials in the grinding process.
The strength coefficient of broken particles is determined by the specific gravity, strength, and toughness of the material. Generally, the higher the specific gravity of the material, the greater the strength coefficient of the broken particles. Similarly, the higher the strength and toughness of the material, the higher the strength coefficient of the broken particles. Therefore, for different materials, different grinding technologies can be adopted to improve the strength coefficient of broken particles.
For example, the strength coefficient of broken particles of coal can be improved by stirring, mixing, and collision between the particles during micro-grinding, so that the surface area of the mixed particles increases and the strength coefficient of the broken particles is improved. In this case, a jet mill is often used.
In addition, nano-grinding processes such a as oscillating or vibrating mills, ball mills, or ultra-fine grinding mills can be used in materials requiring less strength of the broken particles. In this method, the materials can be ground to particles of the same size, and the strength coefficient of the broken particles can be improved.
Finally, the strength coefficient of broken particles of some materials can be significantly improved by ultra-fine grinding. In this case, an ultrafine grinding mill is required to achieve a high strength coefficient of the broken particles. This method is often used for materials such as titanium dioxide, barium sulfate, calcium carbonate, volcanic ash, alumina and other materials.
In conclusion, the strength coefficient of broken particles depends on the specific gravity, strength, and toughness of the material, so the grinding process adopted needs to be changed according to the material characteristics. This will enable the grinding process be effective and help improve the strength coefficient of the broken particles in order to ensure that the material achieves a good practical application value in the grinding process.
