A tailings grading ore drawing device

Abstract

The invention relates to a tailings classification ore drawing device, which belongs to the technical field of mineral processing engineering. The tailings grading ore-drawing device is divided into four areas. The middle area is equipped with a power distribution room. The left and right sides of the power distribution room are sequentially equipped with a slurry feeding device, a mixing chamber and a coarse sand tailings container device. One side is provided with a fine sand tailings container device, the coarse sand tailings container device and the fine sand tailings container device are connected through the medium sand tailings container device, the coarse sand tailings container device, the medium sand tailings container device and the fine sand tailings container device The ore container device includes a mud scraping device, a container and a folding plate device, and the area between each mud scraping device and the container forms a water-sand launder. This device uses the tailings container device, so that the classified tailings can be easily discharged separately. This device can significantly reduce the height of the tailings dam's infiltration line, thereby greatly improving the stability of the tailings dam.

Description

technical field [0001] The invention relates to a tailings grading ore drawing device, which belongs to the technical field of mineral processing engineering. Background technique [0002] China is a big mining country, and about 300 million tons of tailings are produced by ore dressing every year. Except for a small part as mine filling or comprehensive utilization, most of them are stored in tailings dams. Tailings pond refers to the place where dams are built to intercept valley mouths or enclosures to store tailings of metal and non-metal mines. It is a necessary facility to maintain the normal production of mines. my country is a big mining country, and mines in metallurgy, nonferrous metals, chemical industry, nuclear industry, building materials and light industry have tailings facilities. Whether the tailings reservoir can operate safely and stably plays a vital role in mine production. Once the dam body becomes unstable and damaged, the tailings, mud and water in t...

AI Technical Summary

Problems solved by technology

When tailings are discharged with high slurry concentration, high velocity and large flow, the flow of tailings on the slope is similar to the flow of debris flow, which is a kind of overall moving movement. At this time, tailings deposits will not Obvious coarse, medium and fine particle partitions are formed in front of the dam, basically the whole tailings particle gradation is deposited on the sedimentary shoal, and the tailings will no longer be graded during the deposition process, which is not conducive to the drainage of the tailings dam body, thus Increase the height of the dam soaking line, greatly increasing the risk of tailings dam landslides
