We are exploring the integration of ball preparation and use, focusing on new material design, process development, and grinding optimization. We are developing ball mill energy conservation and consumption reduction methods, implementing digital and scientific management of ball preparation and operation, and achieving the long-term development of ball milling. Therefore, it is necessary to understand the wear progression of balls made of different materials during the grinding process to assist in developing balls tailored to meet specific needs.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a schematic diagram of the structure of the grinding balls in the method for acquiring the wear process of grinding balls in the motion state of a ball mill proposed by the present invention. DETAILED DESCRIPTION

[0015] Reference Figure 1 The present invention proposes a method for obtaining the wear process of grinding balls in a ball mill motion state, comprising the following steps:

[0016] S1. Manufacturing a specific grinding ball, the grinding ball comprising an outermost wear-resistant material layer 1 and a calibration layer 2 located inside the wear-resistant material layer 1 and having a material different from the wear-resistant material layer 1 and the material;

[0017] S2, putting the grinding balls in S1 into the ball mill to perform grinding work;

[0018] S3. Sampling the material in the ball mill and testing the sample to obtain the content of the calibration layer 2 material in the sample;

[0019] S4. The wear process of the grinding balls can be determined based on the content of the calibration layer 2 material in the sample, allowing researchers to understand the wear of the grinding balls in the ball mill in real time while in motion, thus providing an experimental basis for the research of new grinding ball materials.

[0020] In a further embodiment, sampling is performed at intervals, and each sample is tested to determine the content of the calibration layer 2 material in samples collected at different time intervals. The content of the calibration layer 2 material collected at different time intervals is then compared and analyzed to determine the wear progression of the grinding balls. Specifically, the time interval when the calibration layer 2 material is first detected can be used to determine when the grinding balls begin to wear. The content of the calibration layer 2 material in each time interval can be used to determine when the grinding balls experience significant and minimal wear. The collection of this data helps to construct a correlation model between process parameters such as filling rate, rotational speed, material-to-ball ratio, and grinding concentration during the grinding ball's service life and mill efficiency, thereby identifying a key process parameter combination for optimal grinding performance.

[0021] Furthermore, the values ​​of the calibration layer 2 material obtained in two adjacent time periods are subtracted to obtain increments. All increments are then compared and analyzed to determine the speed of wear of the grinding balls in different time periods. This helps to timely understand the working status of the ball mill and make corresponding process adjustments to ensure that the ball mill can operate at optimal conditions for a long time, thereby helping to establish a corresponding relationship between the grinding balls and the mill.

[0022] In a further embodiment, the calibration layer 2 is provided with multiple layers, which are arranged in sequence from the outside to the inside, and the materials used in each calibration layer 2 are different; when the sample is tested, the content of the material of each calibration layer 2 in the sample is obtained to judge the degree of wear of the grinding ball according to the content of the material of each calibration layer 2 in the sample.

[0023] In this embodiment, the sampling method is to sample the material discharged from the ball mill.

[0024] As can be seen from the above, the present invention sets up a specific grinding ball, and makes the grinding ball include a wear-resistant material layer 1 and a calibration layer 2. When the ball mill enters the working state, the material in the ball mill is sampled and the sampled sample is tested to obtain the content of the calibration layer 2 material in the sample; and the grinding process of the ball mill is judged according to the content of the calibration layer 2 material in the sample, so that researchers can understand the wear of the grinding balls in the ball mill in a moving state in real time, thereby providing an experimental basis for the research of new grinding ball materials, helping to obtain new high-performance grinding ball materials with good genes, and then obtain grinding balls that are resistant to impact wear and have extended service life.

[0025] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
