Problems solved by technology

[0011] Aiming at the limitations of the existing test method for the residence time of materials in cement ball mills, the present invention proposes a test method for the residence time of materials in cement ball mills based on automatic image recognition technology. In the process of content quantification, problems such as inaccurate testing, inconvenient operation, and inability to complete testing at the production site were encountered. At the same time, the entire working procedure of the fluorescein testing method was optimized to achieve more convenient and accurate test results.

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, preferred embodiments are given to further describe the present invention in detail. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0030] A method for testing the residence time of materials in cement mills based on image recognition technology, the specific steps are as follows:

[0031] This example takes a cement grinding production line as an example. The production line is a combined closed-circuit grinding system composed of a CLF170-100 roller press and a Φ4.2*13.5m two-chamber ball mill ( image 3 ), the system can close the powder classifier for open-circuit process production. Among them, the output of P.O42.5 cement platform pro...

Abstract

The invention discloses a method for testing residence time of materials in a cement mill based on an image recognition technology, and belongs to the technical field of cement production. The method comprises four procedures, namely, fluorescein material cake sample preparation, fluorescein feeding and taking, fluorescein image acquisition and fluorescein image recognition and quantification. The retention time of the materials in the cement mill can be rapidly and accurately tested. A plastic material cake is prepared by adding water into fluorescein powder and the mill entering materials, the fluorescent powder is prevented from being quickly blown to the tail of the mill along with ventilation in the mill to influence a test result, fluorescein recognition adopts an image recognition method, a shooting task can be completed only by using a portable handheld microscope with a low price, shooting of each sample only needs 3-4 minutes, the shooting of all the samples only needs one hour; and by using a computer image recognition technology, quantitative statistics of the fluorescein can be quickly realized, subjective judgment of manual visual inspection is avoided, and a test result is more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a method for testing the residence time of materials in a cement mill based on image recognition technology. Background technique [0002] my country's annual cement output exceeds 2.4 billion tons, and cement has become one of the most important basic building materials for national economic construction. The ball mill has been used in the cement industry for hundreds of years, and it has always been the main equipment for the grinding operation of cement enterprises. The grinding production process of most cement enterprises in China contains ball mills. The residence time of materials in the ball mill is one of the important reference indicators for judging the operation status of the cement ball mill and the grinding efficiency. It directly affects the fineness, temperature and quality of the final cement product. Important, it is one of the skills that cement grin...
