On-line full-automatic sampling, sample preparation and moisture determination system and method for iron ore

Abstract

The invention relates to the technical field of iron ore raw material sampling, sample preparation, detection and analysis, and provides an on-line full-automatic iron ore sampling, sample preparation and moisture determination system and method. A sampling transmission unit comprises a primary sampling machine, sample transmission equipment and a secondary sampling machine; the primary sampling machine is connected with the granularity determination unit and the robot sample preparation analysis unit through sample transmission equipment and conveys samples; the particle size measuring unit comprises a particle size screening machine and a particle size weighing system; the robot sample preparation analysis unit comprises a rotary sample collector, a sample barrel cleaning device, a primary jaw crusher, a primary division machine and the like; the rejected sample unit comprises a rejected sample transfer belt conveyor, a system rejected sample bucket elevator and a system rejected sample output belt conveyor. The method has the advantages of high accuracy of particle size determination and moisture analysis data, strong sample preparation representativeness, high automation degree and high sample preparation efficiency.

Description

technical field [0001] The invention relates to the technical field of iron ore raw material sampling, preparation, detection and analysis, in particular to a system and method for on-line automatic sampling and preparation of iron ore and moisture determination. Background technique [0002] The iron ore sampling, preparation, detection and analysis equipment is a kind of system device used in iron ore mining and production, iron ore bulk loading and unloading terminals, iron and steel production and other industries. . [0003] At present, most iron ore sampling and preparation equipment and systems can only complete online sampling, preliminary sample preparation, particle size determination, etc., while iron ore online moisture measurement, industrial analysis sample grinding, etc. all require manual participation in stand-alone measurement. Analysis and sample preparation. [0004] The shortcomings of traditional iron ore sampling and preparation systems and equipment...

AI Technical Summary

Problems solved by technology

[0003] At present, most iron ore sampling and preparation equipment and systems can only complete online sampling, preliminary sample preparation, particle size determination, etc. Work such as iron ore online moisture determination, industrial analysis sample grinding, etc. requires manual participation in stand-alone measurement Analysis and Sample Preparation

[0004] The shortcomings of the traditional iron ore sampling and preparation system and equipment are as follows: moisture determination, industrial analysis sample grinding and other work require manual participation, low degree of automation, large sample loss, and manual measurement and sample preparation process are easier to introduce measurement , sample preparation deviation, resulting in large fluctuations in the final measurement and analysis results
