Problems solved by technology

Due to the randomness of manual sampling and the influence of human factors, it is difficult for the grade of the sample taken to truly reflect the grade of the ore in the entire carriage. At the same time, the workload of manual sampling is heavy, and the grade of the ore can only be obtained after sending samples for testing. Prolonged mining working time, causing inconvenience. Although there is a small-scale grade detection device, the amount of ore detected is small, and it is impossible to estimate a large area of ​​ore. Inconvenient to summarize and analyze, inconvenient to use

Abstract

The invention discloses an automatic iron ore grade detection system and an automatic iron ore grade detection method. The automatic iron ore grade detection method comprises the following steps: integrating multiple types of measuring and intelligent control equipment, automatically measuring the specific gravity of ores, establishing a relationship between the specific gravity and the grade of iron ore through experiments, inversely solving the grade of the iron ore according to the specific gravity, finally saving measured data into a databank, and automatically printing acceptance verification receipts. By adopting the automatic iron ore grade detection system and the automatic iron ore grade detection method, the volume and the weight of ores in a whole carriage can be easily and rapidly measured, the grade of the whole ores can be really and rapidly obtained, the problem that the grade of ores is artificially depleted is solved, the labor cost of sampling and testing is greatly reduced, the conclusion can be easily obtained, and the device is convenient to use.

Description

technical field [0001] The invention relates to the field of automatic detection of iron ore grade, which can automatically measure the weight, volume and grade of iron ore in real time during the mineral processing production process. Background technique [0002] Ore is a rock that contains useful minerals and has mining value. Any natural collection of minerals in the earth's crust, under the conditions of modern technical and economic levels, can extract metals or other mineral products necessary for the national economy on an industrial scale, called ore . [0003] Ore grade refers to the content of useful components or useful minerals per unit volume or unit weight of ore, generally expressed in weight percentage. Mineral product grade is the main indicator to measure the economic value of ore deposits. The percentage of useful ingredients (elements or compounds) contained in ores or products. [0004] The grade and authenticity of the ores mined and purchased by iro...
