Description

Fine particle mineral screening device

Technical Field

Background

The fine particle mineral containing mud, such as the fine particle mineral which is not suitable for heap leaching treatment and is separated out before heap leaching of gold ore, such as the fine particle mineral to be subjected to medium removal and desliming in heavy medium ore dressing, has larger specific surface area and higher external moisture content of the material, so that the particles are easy to be bonded into clusters and attached to large blocks, and the fine particles are difficult to pass through a sieve mesh to realize screening. In particular, a fine clay mineral which is easily agglomerated is contained, and it is very difficult to screen the mineral even when the moisture content is low.

At present, the materials containing mud and fine particles are generally treated by a classification cyclone, a high-frequency vibration sieve or an underwater sieve. Although the classifying cyclone has the advantages of strong processing capacity and large processing capacity, the classifying accuracy is difficult to meet the requirement. The high-frequency vibration sieve has strict classification and high classification precision, but has lower processing capacity and is difficult to adapt to the requirements of screening and processing large-batch fine particle materials. The underwater vibrating screen can realize the loosening of the mineral containing the water and the mud fine particles by means of the disturbance of the water medium, thereby being capable of efficiently finishing the screening, realizing the strict classification and being capable of implementing the screening of the large-batch fine particle materials.

As the underwater vibrating screen in the prior art, the screen meshes are arranged on the upper surface and the lower surface of the screen frame, and the screen frame and the screen meshes are wholly immersed under water when the underwater vibrating screen is used. After a large amount of materials are fed, the upper and lower sieve surfaces can realize the sieving function through vibration and water disturbance, and the processing capacity is greatly improved. However, because the whole screen frame is obliquely immersed under water, the materials which are screened by the upper screen surface can pass through the screen frame again under the action of water power and gravity, so that the screening efficiency is reduced.
