Description

technical field [0001] The invention belongs to the field of mineral processing and relates to a wet ultrasonic vibrating screen. Background technique [0002] The so-called sieving analysis is the process of dividing the material into several particle size grades through a series of sieves with different sieve sizes. It is an important method for analyzing the particle size composition of materials in the field of mineral processing, and has very important applications in the field of mineral processing research and production. . [0003] At present, the methods commonly used in the laboratory for material screening involved in the beneficiation process are: [0004] 1. Dry sieving. When the material contains water, less mud, regular shape, and the requirements for analysis results are not very strict, and the sieving particle size is relatively coarse (generally greater than 0.074mm), dry sieving can be carried out directly. Disadvantages: Since wet screening is commonly...

AI Technical Summary

Problems solved by technology

Disadvantages: Since wet screening is commonly used in the beneficiation process, the particle size of the grinding product is fine, there is muddy phenomenon and the product has high water content, it is difficult to directly apply dry screening, and more is only used as an auxiliary operation after the screening operation; For ultra-fine screening of some mineral particles with small specific gravity (such as 0.01mm screening for coal slime particles), and ultra-fine screening of some irregularly shaped mineral particles (such as 0.01mm screening for sheet silicate mineral mica) , dry sieving is also difficult to effectively separate

Disadvantages: Unlike dry sieving, the sieving process can be completed with the help of various mechanical vibrating screens

At present, when performing wet sieving operations in laboratories, physical and mechanical vibrations are generally generated by hand sieving, so there is a problem that the screening efficiency is not high enough in the screening process, especially for some fine materials (particle size is 0.037mm Below) materials, the problem of low screening efficiency is particularly prominent

At the same time, due to the great surface energy of fine-grained minerals, the fine particles (generally below 0.037mm) of most minerals in water more or less have flocculation phenomenon, and the particle size will increase significantly after flocculation, which will lead to sieving Severe discrepancies in the results

In addition, continuous wet sieving by hand sieving is also a great test for the operator's skills and physical strength, and the final sieving effect is not ideal.

Therefore, the existing wet sieving mode in the laboratory still has certain deficiencies and needs to be further improved or optimized.
