Abstract

The invention relates to automatic classification experiment system for a fine-grain material. The automatic classification experiment system is characterized in that a stirring shaft extending to the lower part of a transparent settling tank is arranged in the transparent settling tank, stirring blades are mounted at the lower end of the stirring shaft, the upper end of the stirring shaft is connected with an output shaft of a stirring motor, the stirring motor is fixed on a top cover of the transparent settling tank, an ore pulp injection pipe and a dispersing agent injection pipe are connected onto the top cover, an ore pulp funnel is arranged at the top of the ore pulp injection pipe, and a dispersing agent injection valve is arranged on the dispersing agent injection pipe; the center of the bottom wall of the transparent settling tank is connected with a bottom center pipe, and a bottom valve is mounted on the bottom center pipe; one side of the bottom wall of the transparent settling tank is connected with a discharge manifold, an overflow hole is formed in the upper end of the discharge manifold, the lower edge of the overflow hole is flush with the lower level liquid line of the transparent settling tank, the lower end of the discharge manifold is connected with a first discharge pipe, a second discharge pipe, a third discharge pipe to an nth discharge pipe, and a first discharge valve, a second discharge valve, a third discharge valve to an nth discharge valve are mounted on the first discharge pipe, the second discharge pipe, the third discharge pipe to the nth discharge pipe respectively. The experiment system is high in automation degree and low in manual cost.

Description

technical field [0001] The invention relates to an ore dressing test device, in particular to an automatic classification test system for fine-grained materials, which belongs to the technical field of ore pulp treatment. Background technique [0002] According to the world resource situation, rich ore resources are becoming increasingly depleted, and poor, miscellaneous, and fine-grained disseminated ores are increasing year by year. The analysis and research on fine-grained materials has become one of the development trends and necessary requirements for future mineral processing. In the beneficiation process, determining the particle size composition and metal distribution of fine-grained materials is one of the important factors in determining the beneficiation method and process flow, and is an important parameter for evaluating operational indicators, providing guidance for strengthening the recovery of useful minerals in specific particle sizes.

Problems solved by technology

[0006] The elutriation method is usually used as a standard for calibrating other water analysis instruments, but due to its long experimental time and heavy workload, it usually takes 8 hours to complete the water analysis experiment with two graded particle sizes such as 10 μm and 20 μm, resulting in low work efficiency. Human error is large, which brings difficulties to beneficiation production and research
