Description

technical field

[0001] The invention relates to a laboratory-use pulsating ultrasonic wet-type high-frequency vibration screening device, which belongs to the field of mineral processing equipment. Background technique

[0002] In the industrial production and laboratory tests of mineral processing, it is often necessary to screen and classify the products at each stage of mineral processing, and then analyze the products with different particle sizes after screening to obtain the particle size composition of the products and judge the quality of the products. Especially in the grinding stage, the analysis of the particle size composition of the grinding products is an important means to judge the quality of the grinding process. Whether the particle size composition of the grinding products is reasonable will directly affect the subsequent sorting operations.

[0003] Currently, dry screening and wet screening are the most common screening methods. Dry screening is mainly ...
