Technical Field

[0001] The utility model relates to the technical field of bentonite production, in particular to bentonite production equipment which is convenient for grading and screening. Background Art

[0002] Screening is the process of using a screen to allow fine particles smaller than the screen holes to pass through the screen surface, while coarse particles larger than the screen holes are retained on the screen surface, thereby completing the process of separating coarse and fine materials.
