Description

Technical Field

[0001] The utility model relates to the field of ceramic grinding balls, in particular to a ceramic grinding ball with material wear testing equipment. Background Art

[0002] Grinding is a very important link in the field of materials. With the development of industrial technology, the replacement of grinding mills is becoming more and more frequent. Large-scale grinding mills have long become a trend. They have the advantages of large loading capacity, high grinding efficiency, large production capacity, high degree of automation, and easy management. However, the disadvantages are low operational flexibility, large equipment loss due to intermittent operation, and very large losses caused by each shutdown. Therefore, it is very inconvenient for industrial mills to be selected or improved in process. First, the number of grinding balls required for the selection of grinding balls for industrial mills is huge, and the selection may fail, which will incur high costs; secondly, the number of defective materials generated during the testing process of industrial mills is huge and difficult to handle; and the frequent replacement of processes is cumbersome and time-consuming, which occupies a large part of production capacity and affects production continuity. This also determines that we need to take other approaches to simulate the selection or process improvement process of industrial mills, simulate and truly reflect the use of industrial mills under laboratory conditions as much as possible, put more preliminary selection experiments in the laboratory, reduce the number and frequency of industrial-level experiments of industrial mills, and strive to complete industrial experiments in one step.

[0003] There are many kinds of industrial mills, and the common grinding ball wear resistance equipment in the laboratory include planetary ball mills, ball bottle mills, jar mills, vertical sand mills and horizontal sand mills. The grinding jars of planetary ball mills, ball bottle mills and jar mills are sealed, and only the grinding balls and materials in the sealed jars can be tested each time during the test, which lacks continuity. The laboratory vertical sand mill is mainly a non-circulating vertical stirred mill, which does not have the function of circulating grinding and energy consumption calculation. Therefore, its testing method is similar to that of ball mills, and it is also for the grinding balls and materials in the cavity. Test; Horizontal sand mill is a closed high-energy mill, and its application field is mainly ultra-fine grinding. It is not suitable for coarse grinding and fine grinding application scenarios dominated by open vertical sand mills; In addition, there are many parameters involved in the actual working conditions of industrial sand mills, including: the type, particle size, particle size grading, and machine addition of grinding balls, the type, solid content, and initial fineness of the grinding material, the temperature, pH, flow rate, discharge fineness, and slurry circulation method of the grinding slurry, as well as the speed of the mill, the type of mill, the volume of the mill, the filling rate of the mill, and the operating power of the mill. Therefore, conventional laboratory mills cannot fully match industrial mills and the actual working conditions of industrial mills. This also leads to the fact that laboratory test results are often not completely consistent with the actual use of industrial mills, which also greatly reduces the persuasiveness of laboratory results.
