The ore is sorted according to density differences in the vertically rising and falling variable speed medium flow, and the ore is distinguished due to differences in particle size and shape.

[0003] The existing jig mainly includes a body, a screen plate, a beneficiation tank, a jig chamber and a driving group. After the jig is used for a long time, the screen holes on the screen plate are often blocked and damaged. The existing jig screen plate is usually fixedly connected to the inside of the body, which is very troublesome, time-consuming and labor-intensive to clean and replace the screen plate.
