Description

TECHNICAL FIELD

[0001] The utility model relates to mineral aggregate classification technical field, and specifically is a kind of mineral aggregate particle size detection and kind identification equipment. BACKGROUND

[0002] The division of ore particle size grades is crucial for ore processing, utilization and beneficiation processes. Different particle size grades can affect the physical and chemical properties of the ore, which in turn affects the efficiency of its extraction and processing. For example, coarser ore particles may require more energy and time to break and grind, while finer particles may be easier to float or undergo other chemical treatments.

[0003] There is a Chinese public patent CN214201085U, which discloses an ore particle size online detection system based on image recognition technology. The system uses an arc-shaped flat material dust collector to flatten the ore material on the belt conveyor, ensuring that the distance from the material surface on the cross-section of the belt conveyor to the lens of the CCD industrial camera is exactly equal. This allows the material size to maintain the same proportion as the image. However, in the use of the above-mentioned device, although the arc-shaped flat material dust collector ensures that the distance from the material surface on the cross-section of the belt conveyor to the lens of the CCD industrial camera is exactly equal, it may cause the CCD industrial camera to only detect the particle size of the surface ore material. The covered ore material cannot be detected by the CCD industrial camera, resulting in that the device is not comprehensive enough in detecting the particle size of the ore material during use.
